The Orioles have gone 10 straight American League East series without losing one since April – going 8-0-2 - but they have a challenge to win their current series with the Toronto Blue Jays.

After Toronto’s 6-3 win Monday in 10 innings, the Orioles now need two straight wins to take another division series. The Orioles are now 24-15 for the year in AL East games and are 22-11 during the unbeaten 10-series run within the division.

Brandon Belt’s two-run homer in the 10th off Mike Baumann - who was optioned to Triple-A today - gave Toronto a 5-3 lead. That lead grew to three runs when Vladimir Guerrero Jr. doubled and scored on a wild pitch.

That double was Guerrero’s first extra-base hit this year off Baltimore pitching. After getting three hits last night he is now batting .200 (8-for-40) with a .529 OPS in 11 games this season versus Baltimore, with one double and two RBIs.

Toronto (70-56) is in third place and moved to within 7 1/2 games of the division-leading Orioles. The Blue Jays are now 38-29 on the road and 18-7 in their past 25 road games. They are 12-23 versus AL East teams and 8-7 in extra innings.

The Orioles aren’t listing starters for Thursday night or the three-game weekend series against the Rockies. The rotation is fluid after the decision to push back Jack Flaherty.

Flaherty said he didn’t bounce back after his last start in San Diego. Specifics are scarce.

“It was decided yesterday pregame to just give him a little bit extra time,” said manager Brandon Hyde. “In his catch play yesterday, there’s a little bit of soreness, and so we just wanted to give him a little bit of a break, and we moved up Dean (Kremer) to today.”

Hyde described it as “general” soreness, which “normally goes away over the course of between starts, and we feel like we want to be a little bit precautionary with him and just let him not make his start today.”

Flaherty was acquired from the Cardinals at the trade deadline to provide a veteran presence and someone who could handle a heavier workload, and a six-man rotation was built to spare the younger arms and make it easier control innings. But Flaherty's return date after three starts with the Orioles isn’t determined.

The Orioles have changed starters tonight, with Jack Flaherty scratched from his assignment.

Dean Kremer is starting against the Blue Jays, and Thursday is now listed as TBA.

A couple breaks in the schedule and a six-man rotation put Kremer on six days’ rest following his outing in San Diego.

No explanation was provided for the switch. Manager Brandon Hyde will address it later today in his media session.

Flaherty was supposed to make his fourth start with the Orioles. He’s allowed 10 runs over eight innings since his one-run debut in Toronto.

SAN DIEGO – Be careful with the soft spots in the schedule.

The footing can get slippery.

The Orioles are playing teams below .500 in four out of the next five series, beginning with the Padres and including a trip to Oakland. A reprieve on paper. A trap on the field the past two nights.

Left-hander Blake Snell held the Orioles to two runs over six innings, the bullpen was sturdy, and the Padres won again 5-2 before an announced sellout crowd of 42,318 at Petco Park.

The Orioles have gone 3-3 on their West Coast excursion, and their lead over the second-place Rays is down to two games going into the off-day.

After a 4-1 win Monday night and a 10-3 loss on Tuesday, the Orioles wrap up their series at San Diego tonight. The winner this evening will take this series.

The Orioles (74-46) ended play Tuesday three games ahead of Tampa Bay for the American League East lead.

The O's are 10-6 in rubber-match games. Should they win this game, they will improve to 24-12-3 in series play in 2023, and to 13-5-2 in road series. 

The Orioles, even after the loss yesterday, have won four of six, eight of 12, 11 of 16, 15 of 23 and 25 of their past 36 games. They are 38-23 on the road, 9-5 in August and 20-11 in the second half.

Heading into Tuesday's game, the Baltimore rotation had allowed three earned runs or fewer 16 times in the previous 17 games. The rotation ERA was 3.56 in that span. And if you took away Kyle Gibson allowing nine runs last Friday, the rotation ERA was 2.88 in the 16 games with three earned runs or fewer.

The Orioles didn’t fall behind to the Astros this afternoon. They were tied once and grabbed another lead right away. The margin got tight and they found more padding.

They pitched, played defense and hit in the clutch.

Getting swept in a series just isn’t in their DNA.

Dean Kremer worked seven innings for his 11^th quality start, Adley Rutschman and Ryan Mountcastle drove in two runs, and the Orioles held on to defeat the Astros 5-4 before an announced crowd of 22,981 at Camden Yards.

Mountcastle extended his hitting streak to 12 games with a two-run shot off rookie Hunter Brown in the seventh, and the Orioles improved to 71-44. They’re 2 ½ games ahead of the second-place Rays, who play tonight.

The Orioles have not been swept in a series this year and will need a win this afternoon at Oriole Park to avoid that fate against the Houston Astros.

Houston rallied in the ninth to beat the Orioles 7-6 Tuesday night. Last night they scored three early runs and five late for an 8-2 win. 

In 18 innings this series, the Orioles staff has allowed 21 hits and 15 runs with nine walks and 20 strikeouts.

Coming into this series the O's team ERA was 2.15 during a 7-1 run. And it was 3.23 as they had won 21 of the previous 28 games.

But Houston has put up seven runs and eight runs in winning the first two games, and the Astros scored 10 runs in seven innings of work by the Baltimore bullpen.

The Houston Astros were averaging 4.76 runs per game to rank sixth in the American League as this series began. But the O’s have seen the best from their lineup as they rallied to win in the ninth Tuesday and pulled away late in the game last night to win 8-2.

That is 15 runs over two games against a Baltimore staff that came into this series on a good roll. Heading into this series, the O’s were 7-1 their past eight games with a 2.15 team ERA and 21-7 the previous 28 games with an ERA of 3.23.

Baltimore had allowed just seven runs during a four-game win streak. The O’s staff gave up 10 runs total in taking three of four from Toronto and just six runs in a three-game sweep of the New York Mets.

But Houston was playing good baseball coming into Baltimore and it’s continued over two days and now they can sweep this three-game series this afternoon.

Five times this year the Orioles have lost the first two games of a three-game series, but they won the last one to avoid being swept. It happened against Texas, Milwaukee, the Chicago Cubs, Minnesota and the Los Angeles Dodgers.

Three forearm smashes and a hand slap. That’s what awaited Adam Frazier tonight after he crossed home plate in the first inning. Before he reached the top step of the dugout.

In the middle of the latest beating administered to Yankees starter Luis Severino.

The Orioles sent 11 batters to the plate, scored seven runs and turned ESPN’s first Camden Yards broadcast in five years into a challenge to avoid using every note and anecdote before the top of the second.

Frazier drove a fastball onto the flag court in right field for a three-run homer, the sixth consecutive Oriole to reach base in a 9-3 rout of the Yankees before an announced crowd of 37,429.

The three-game series drew 114,816.

The Orioles and New York Yankees will play tonight to wrap up this series and their 2023 season series. The clubs will not meet again this year after tonight.

The Orioles blanked New York 1-0 Friday night on Anthony Santander’s walk-off home run in the last of the ninth. New York won 8-3 last night as right-hander Tyler Wells allowed three runs over 2 2/3 innings in his third straight ineffective outing. Ryan Mountcastle hit a solo homer Saturday night, his 13^th.

The Orioles (63-41) have lost three of four games and are 6-6 over their past 12 games. They are 31-21 at home and 15-9 in July. They are about to close out their fourth straight winning month of the season, fifth if you count going 1-0 in March.

The Orioles need a win tonight to keep an impressive streak going. They have not lost an American League East series since April 9, when they started 0-2 in division series. Since then they are 6-0-2, with the winner of this series to be determined by tonight’s game.

The last time the Orioles had a streak longer than eight consecutive non-losing division series was 11 in a row from Aug. 1-Sept. 30, 2012. This run has seen the Orioles winning series versus Boston, Tampa Bay, Toronto, New York and Toronto. They then split series at Tampa Bay and New York before going 3-1 against the Rays last weekend.

The Orioles are hosting an ESPN game tonight for the first time in five years and trying to win their 20^th series following last night’s 8-3 loss to the Yankees before the second sellout crowd of the season.

Adley Rutschman is leading off again after going 0-for-2 last night with a walk and hit-by-pitch. His on-base streak has reached a career-high 14 games.

James McCann is catching, with Rutschman serving as designated hitter.

Adam Frazier is in left field and Jordan Westburg is the second baseman.

Gunnar Henderson is batting second and playing shortstop. His double last night snapped an 0-for-15 streak.

For the Orioles, this has been a road trip marked by close wins. They are 4-1 on the trip, winning the four games by a combined five runs after Monday’s 3-2 win over the Philadelphia Phillies.

The Orioles (62-38) are playing .620 ball at the 100-game mark they reached last night. They now lead the American League East by 2 1/2 games over Tampa Bay, 6 1/2 over Toronto and 9.0 over Boston and New York.

The Orioles have won three in a row, five of six and 13 of 16 games. They have outscored their opponents 93-57 over the 16 games. They are 8-3 in the second half and have now gone 72 consecutive series without being swept.

In Orioles club history, the six teams that played in the World Series all won 59 or more of their first 100 games. The 1969 team posted the best 100-game mark at 69-31, followed by the 1979 team (67-33) and the 1966 World Series champions (66-34). The teams in 1970, 1971, 1997 and 2023 all went 62-38. The 1983 World Series winners won 59 games. Every O’s team that won 62 or more advanced to the postseason.

Jordan Westburg and Ryan Mountcastle hit solo homers last night, and Colton Cowser notched his first career extra-base hit with an RBI double in the ninth that broke the 2-2 tie. Westburg hit his first career homer and Mountcastle hit No. 12 this year. He blasted a slider with a 112.3 mph exit velocity, and hit the ball 451 feet out over the center field fence. It is the fourth-longest homer by an Oriole this year.

The Orioles road trip continues tonight in Philadelphia, where they play the first of three games at Citizens Bank Park. The Orioles won three of four against the Tampa Bay Rays, winning the three games by four total runs to grab a two-game lead atop the American League East.

The Orioles (61-38), who play their 100^th game tonight, were 6.5 games back of Tampa Bay on July 1 and six games back on July 4. So far this month, the Orioles are 13-6 while the Rays are 4-14, and they have gained 8.5 games on the Rays in that span.

With Sunday’s 5-3 win at the Trop, the Orioles improved to 6-3 this season against Tampa Bay and to 6-0 in games decided by two or fewer runs. The Orioles are 15-10 their past 25 games versus the Rays after going 2-27 in the previous 29.

They also gained their first series win at Tropicana Field since June 23-25, 2017.

The Orioles have now won four of five, 12 of 15 and 13 of their past 18 games. They are 7-3 since the All-Star break, and a season-high 23 games over the .500 mark.

Dean Kremer didn’t view today’s start as some sort of revenge game. His goal was to give the Orioles a chance to win and avoid their first series sweep in 14 months. The opponent presented an opportunity to visit with friends from his former organization. Don’t read more into it.

Tyler Wells threw 40 pitches in the second inning last night and was done. Kremer threw 37 in the first and tried to rework the script.

The Orioles fell behind by two runs, answered back with four in the bottom of the first as a sudden rain shower sent fans scrambling for cover, and produced their 34^th comeback win to lead the majors. But Kremer fell one out short of qualifying for the decision.

Ramón Urías doubled twice and drove in three runs and Gunnar Henderson hit his 15^th home run in an 8-5 victory over the Dodgers before an announced crowd of 22,248 at Camden Yards. The bullpen covered the last 4 1/3 innings after Kremer was charged with five runs in 4 2/3.

The Rays lost in Texas and are percentage points behind the Orioles for first place as the teams begin a four-game series Thursday night at Tropicana Field.

In the 14th round of the 2016 MLB Draft, with pick No. 431 overall, the Los Angeles Dodgers selected right-handed pitcher Dean Kremer from the University of Nevada-Las Vegas. He would pitch on their watch until July 18, 2018, when he and four other players were traded by the Dodgers to the Orioles for Manny Machado.

Today, for the first time in his career, Kremer will face the team that drafted him. And he will try to pitch the Orioles to a win in this series to avoid a three-game sweep after Los Angeles won 6-4 Monday night and 10-3 last night.

Kremer signed with the Dodgers for a bonus of $147,500 and reported to their rookie league team to make his pro debut on July 3, 2016 for the Ogden Raptors. He was pitching in High-A ball for most of the 2018 season and had just moved to Double-A, where he had made one start, when he was traded to the Orioles. They assigned him to Double-A Bowie, where he went 4-2 with a 2.58 ERA in eight starts to finish up the 2018 season.

Kremer (10-4, 4.59 ERA) got off to a slow start this season. His ERA was 6.67 at the end of April and 5.80 after his first start in May. But he has pitched better lately and has allowed two earned runs or fewer in four of his past six starts. In his first outing out of the All-Star break, on Friday against Miami, he gave up two hits and one run over six innings on 97 pitches.

The Orioles are 13-6 in his 19 starts, winning five of his last six games.

Cedric Mullins’ latest trip to the injured list appears related to his previous stop, which lasted almost a month.

Mullins was shut down with a strained right groin. He exited Saturday’s game with tightness in his right quadriceps and returned to the IL this morning with a right adductor groin strain.

“It’s just his upper leg, so groin, quad,” said manager Brandon Hyde. “Felt it in his quad, originally. The soreness is moving around in that upper leg area. It’s a lower-body injury that we’re just going to take a little more time with.

“It has been progressing, but it’s not progressing at the rate that we were hoping, and so the right thing to do is make sure he’s all the way healthy and running well before we activate him.”

Mullins is eligible to return on Wednesday, which might be an overly ambitious goal.

The Orioles needed length out of their bullpen today and recalled Logan Gillaspie from Triple-A Norfork. Cedric Mullins has gone on the 10-day injured list with a right adductor groin strain, a move that’s retroactive to Sunday.

Mullins hasn’t played since Saturday night, when the club announced that he felt tightness in his right quadriceps. He missed almost a month with a groin injury before returning on June 24.

The roster is back to 13 pitchers and 13 position players.

Gillaspie has appeared in 11 games with the Orioles and posted a 6.00 ERA and 2.111 WHIP in nine innings. He’s made 21 appearances with Norfolk and registered a 3.91 ERA and 1.478 WHIP in 23 innings.

Gillaspie’s last appearance was Sunday, when he tossed one inning.

The Orioles begin the second half of the season with a three-game series against Marlins and Gunnar Henderson staying at shortstop tonight and atop the order.

Ryan Mountcastle is on the bench. Ryan O’Hearn gets the start at first base.

Jordan Westburg is playing third base. Aaron Hicks is in right field, with Anthony Santander serving as designated hitter.

Cedric Mullins is batting sixth behind All-Star Austin Hays.

Orioles starters have strung together five quality starts in a row during a five-game winning streak, posting a 1.67 ERA during that stretch.

One of the Orioles’ post-break decisions has been made and revealed.

It took less than 24 hours after the last out of the All-Star Game.

The rotation is set for the weekend series against the Marlins at Camden Yards, with some of the anticipated rearranging. Dean Kremer starts Friday night, followed by Kyle Gibson Saturday night and Kyle Bradish Sunday afternoon.

The Marlins are expected to start Sandy Alcantara and Braxton Garrett in the first two games, with Sunday TBA.

The break allowed manager Brandon Hyde to push back Tyler Wells, who is emerging as the staff ace but has thrown 104 2/3 innings, which is one more than his 2022 total.

NEW YORK – The towering fly ball to Colton Cowser tonight in the first inning drew a roar from the Yankee Stadium crowd but didn’t get close to the warning track in left field. Cowser camped under it and waited, a 44-degree launch angle providing time for fans to realize their mistake.

Next came the first at-bat, with one out in the second inning. Cowser fell behind 1-2, twice taking changeups for strikes, and lined a curveball 107.7 mph to shortstop Anthony Volpe.

Cowser was checking boxes in his major league debut. Getting the firsts out of the way. Happy for the chance to play and maybe step back from the spotlight in the coming days.

One swing took care of two more.

Cowser lined an RBI single into right field in the sixth inning after the Orioles put runners on the corners with one out against left-handed reliever Nick Ramirez, and he crossed the plate for the first time on Jordan Westburg’s two-run triple.
