HOUSTON – Jack Flaherty is moving to the bullpen.

Orioles manager Brandon Hyde is starting Kyle Bradish in Wednesday afternoon’s series finale in Houston, and rookie Grayson Rodriguez gets the ball Thursday night in Cleveland.

In a six-man rotation, Flaherty would have taken his next turn Thursday in his eighth game with the Orioles since the deadline trade. He’s carrying a 7.11 ERA and 1.674 WHIP in 31 2/3 innings since leaving the Cardinals.

Flaherty hasn’t worked more than 4 2/3 innings in three starts this month, and he hasn’t reached the same level of effectiveness as in his debut in Toronto, when he allowed one run in six frames.

The switch to relief isn’t necessarily a permanent assignment.

HOUSTON – The Orioles have moved on from the party.

They went wild yesterday after clinching a playoff berth, but arrived in Houston with their focus on the seven-game road trip and winning the American League East for the first time since 2014.

“I wanted our guys to enjoy the flight, but I think we’ve done a nice job turning the page,” said manager Brandon Hyde. “We just had our advance meeting and I thought that went really well. I thought guys were in tune to facing (Justin) Verlander today. John Means is ready on the mound. I think we pitched a lot of guys yesterday, had to, but I feel like our guys are ready to play today.”

Center fielder Cedric Mullins, whose sacrifice fly scored the winning run in the 11^th inning, said the mindset shifted on the charter.

“We were making sure we got our rest,” he said. “It’s hard to sleep on a plane sometimes, but get as much as you can, especially after an intense game like that. I think the energy level here is really high, continuing to push forward after the clinch. Now, we want to win the division.”

Orioles closer Félix Bautista, on the injured list with a partial tear in the ulnar collateral ligament in his right elbow, took a potentially significant step today.

He threw off a mound in the Orioles bullpen before the series finale with Tampa Bay.

“He just threw a side this morning,” manager Brandon Hyde said in his pregame press conference. “Sounds like it went pretty well. That was kind of the next step in his throwing progression. So, see how he feels tomorrow. We’re just kind of day-to-day with him right now.”

Hyde was asked if he is pleased with this progress for Bautista, who has not pitched since Aug. 25.

“Yeah. I just ran into him and (head athletic trainer) Brian (Ebel) after the side session and it sounds like it went pretty well. That’s always encouraging," he said.

Ryan Mountcastle remains out of the Orioles lineup tonight after leaving Wednesday’s game with discomfort in his left shoulder.

An MRI was negative and Mountcastle has progressed to taking some swings. Manager Brandon Hyde expressed his optimism again yesterday.

“It’s a lot better,” he said.

Heston Kjerstad’s first major league hit last night was a solo home run. He’s out of the lineup tonight.

Aaron Hicks is in right field and Anthony Santander is serving as the designated hitter. Austin Hays returns to the lineup in left field.

Ryan Mountcastle’s health is trending in the right direction, and he could be nearing a return to the Orioles lineup.

Mountcastle exited Wednesday’s game with left shoulder discomfort but didn’t go on the injured list. He’s out of the lineup again tonight.

“Feeling even better today,” said manager Brandon Hyde. “He’s going to take some swings here coming up, so hopefully he’s available, but it’s a lot better.”

Ryan O’Hearn is playing first base again tonight and Heston Kjerstad is making his first major league start as the designated hitter.

Closer Félix Bautista also has avoided the injured list after suffering a slight tear in the ulnar collateral ligament in his right elbow exactly three weeks ago.

Orioles' right-hander Kyle Bradish was asked last night for his opinion on how he pitched.

“Indifferent,” was his immediate response.

Couldn’t feel that way about everything that happened prior to the game.

The anticipation over Ryan Mountcastle’s MRI results. The predicted roster move that turned into multiple moves and caught many of us by surprise. The observations and lessons learned.

Don’t always trust body language and somber tones.

The grimacing from Orioles' first baseman Ryan Mountcastle last night, followed by his removal from the game and somber tone at his locker, hinted at a serious injury to his left shoulder. He felt and heard a pop. The pain wouldn’t subside. He fidgeted at first base. Bad body language for anyone who can interpret.

The mood within the organization has taken a drastic turn. Smiles and signs of relief.

Manager Brandon Hyde said the Orioles received “great news” on Mountcastle’s MRI this morning. An expected trip to the injured list was scrubbed.

“He’s feeling a lot better,” Hyde said. “The imaging was all positive, so he’s just day-to-day-right now.”

Mountcastle has left shoulder soreness, but it didn’t remove him from the active roster.

Stoked. Excited. Relieved.

Heston Kjerstad summed up his emotions after getting the news last night that the Orioles wanted him in Baltimore. He isn’t in tonight’s lineup, but he reached the majors in his first full professional season.

The wheels were in motion after Ryan Mountcastle injured his left shoulder while fouling off a pitch. Triple-A Norfolk manager Buck Britton pulled Kjerstad from the game after two plate appearances.

“For precautionary or whatever,” Kjerstad said, “and then postgame Buck let me know that I was getting called up.”

Kjerstad called his parents, Dave and Jody, and his siblings. They'll be part of his cheering section tonight at Camden Yards.

The Orioles must proceed through their important four-game series and the ensuing days without their closer and, for now, their starting first baseman. But how long?

Félix Bautista is on the injured list with a slight tear of his ulnar collateral ligament – he’s playing catch on flat ground while the team determines whether he can pitch again this year - but Ryan Mountcastle didn’t join him today.

Mountcastle injured his left shoulder last night and underwent an MRI, but outfielder Heston Kjerstad, the second-overall pick in the 2022 draft and one of the top prospects in baseball, had his contract selected from Triple-A Norfolk and Ryan McKenna was optioned. Mountcastle stays on the active roster and perhaps retains his day-to-day status.

Infielder Terrin Vavra was recalled from Norfolk and transferred to the 60-day injured list to make room for Kjerstad on the 40-man roster. Vavra has a shoulder strain and receives his major league salary and service time.

Also, reliever Bryan Baker was recalled from Norfolk and left-hander Nick Vespi was optioned for a fifth time. Vespi can’t be optioned again without passing through waivers.

Finally everyone - from the clubhouse to the dugout, to the media to the fanbase - can turn their full attention to the Orioles and Tampa Bay Rays series that begins tonight at Camden Yards.

The Orioles begin the four-game set leading the AL East by two games. A split or better would be big for Baltimore. The Rays could use three wins or better. No one will win the division this series or lose it, but the results could have a lot to say about who eventually does both.

The Baltimore offense, which put up 10 runs or more four times in a five-game span, now has scored two and no runs the past two games. They lost the series to St. Louis - their first series loss since mid August at San Diego. They were 7-0 the last seven series until losing against the Cardinals.

Both teams enter this series playing well. Tampa Bay (90-57) has won five of six, 12 of 17, 18 of 25 and 21 of the last 30 games.

Baltimore (91-54) has won eight of 11, 14 of 20, 17 of 24 and 20 of the last 29 games.

Ryan Mountcastle drew a painful walk tonight in the bottom of the first inning.

Losing him could severely hurt the Orioles.

Mountcastle fouled off a sinker from Cardinals' starter Drew Rom to leave the count 2-2, took two pitches out of the strike zone and headed to first base. He was grimacing and rotating his left arm as if experiencing shoulder discomfort.

Head athletic trainer Brian Ebel and manager Brandon Hyde checked on Mountcastle, who swung the arm back and forth and stayed in the game. But the pain was lingering.

He paced after every pitch in the top of the second, rubbed the shoulder, rotated his arm a few more times and at least twice removed the mitt. He followed Ebel down the dugout tunnel, but returned to the field in the top of the third.

The Orioles are closing in on clinching their first playoff berth since 2016 with a magic number of four to clinch. They have bigger fish to fry, of course, and want the AL East championship, but clinching a playoff berth will come first.

The players are not yet ready to talk much about that, even with it so close at hand. They are keeping their one-day-at-a-time approach.

“I mean I think we’ve been saying it the whole year, take it game-by-game. We keep doing that, day-by-day and pitch-by-pitch and hopefully this ends with a playoff spot,” Ryan Mountcastle said this afternoon.

I asked Mountcastle today why and how the Orioles have been so good at being in first place. It is kind of a strange question, yes, but since tying for the AL East lead on July 18, they have been in first place every day since.

With their win today at Minnesota, Tampa Bay is 28-14 in the last 42 games. The Orioles are 29-13.

PHOENIX - The Orioles' path to a series win today at Arizona – and their 85^th victory of the season – was far from easy. They took an early lead, got tied up in a two-run Arizona fifth and had to win this game a second time today.

They did by scoring four runs in the sixth to break a 4-4 tie and beat the Diamondbacks 8-5 to win the last two games of this series.

The O's start a nine-game road trip with a series win and are now 85-51. Baltimore has won eight of 11, 11 of 15 and 22 of its past 32 games as the road trip now heads to Anaheim, California. 

The Orioles had lost their previous four series at Arizona, making today their first win of a series in this ballpark, and they are now 9-15 all-time against the Diamondbacks and 5-10 at Chase Field.

The task was made even tougher today because the opposing starter was Zac Gallen, a right-hander having a great year. He was the National League starting pitcher in this year's All-Star game.

PHOENIX -  Orioles manager Brandon Hyde is still not ready to pass on what the next steps will be for injured closer Félix Bautista. Bautista, who has a 1.48 ERA with 33 saves, made the 2023 All-Star team, but went on the 15-day injured list Aug. 26 with a right UCL injury. The next steps – and what they will look like – may not be completely formulated yet.

Hyde was asked today if it’s possible Bautista can pitch again this season. 

“Well, we are waiting for the inflammation to go down honestly, before we kind of reassess and do anything else. We are letting the inflammation die down and then we are going to make some decisions after that," the manager said. 

As to when that inflammation will lessen is not a question Hyde can answer right now.

“That would be a medical question," he said. "Not really sure, it’s been a while now. Think we are waiting a few more days.”

The Orioles are trying today to claim their 28^th series as they conclude their visit to Arizona.

Ryan Mountcastle has returned to the lineup after missing the past few games due to an illness. He’s batting cleanup and playing first base.

Anthony Santander was hit on the right hand last night in the ninth inning, left the game and underwent testing, and is serving today as designated hitter.

Two positive developments before the first pitch is thrown.

Aaron Hicks, reinstated from the injured list today, is in left field. Ryan O’Hearn is the right fielder. Austin Hays is on the bench.

On the same day that the Orioles claimed their former closer, Jorge López, on waivers from the Marlins, manager Brandon Hyde told the assembled media at Chase Field that former Rule 5 closer Tyler Wells has arm fatigue.

I’m tired from trying to project this month’s bullpen. I’m not getting any closer.

My take from the East Coast is that López is insurance, a depth move with Félix Bautista on the 15-day injured list and Wells perhaps delayed in his return to the Orioles. The timing might be coincidental, but we honestly don’t know if that’s the case.

The trade deadline passed and the only way to acquire players is via claims and minor league deals. López isn’t eligible to make the postseason roster because he arrived in the organization after Aug. 31, but he can assist in the quest to win the division title.

Then again, is he equipped to do so?

PHOENIX – The Orioles are hoping to recapture the magic with right-handed reliever Jorge López. Added by the Orioles today on waivers from Miami, López has not yet reported to the team, but he is going to and the O’s hope he can help them win the American League East.

Being acquired after the cutoff date for postseason eligibility, López will not be able to pitch in the playoffs with Baltimore.

Between the Twins and Marlins this year, López is 6-2 with a 6.13 ERA and 1.574 WHIP over 47 innings. He has a 3.8 walk rate and 6.7 strikeout rate. But when last an Oriole, he was a bullpen weapon who made the 2022 AL All-Star team.

“You know, Lopy is someone a lot of us in that clubhouse are really close with,” manager Brandon Hyde said today in the visitor’s dugout. “Had some really good moments. First half last year was the best closer in baseball. What he did making the All-Star team. It was great to see him a couple of months ago in Minnesota. You know we are hoping he can help us down the stretch.”

They helped López once go from struggling starter to top reliever and the Orioles hope to get him going again when he joins the team.

Ryan Mountcastle is out of the Orioles lineup again tonight in Arizona. He was scratched last night due to an illness.

Gunnar Henderson, who went 2-for-4 last night with two runs scored, stays at shortstop. Adley Rutschman is the designated hitter.

Ryan O’Hearn is the first baseman and Ramón Urías is playing third base. Adam Frazier is the second baseman.

Henderson is batting .330 or better when he’s ahead or even in the count, but .172 when behind.

Anthony Santander is slugging .809 against fastballs since the start of August after slugging .276 against them in July.

PHOENIX – In his fourth year in the O’s organization, Ryan Fuller, 33, is in his second season on the major league staff. He is co-hitting coach, working alongside Matt Borgschulte and offensive strategy coach Cody Asche.

The trio is there to prepare, provide scouting reports, help and work with O’s hitters in any ways they can to make them better.

The Orioles rank fourth in the American League scoring 4.98 runs per game. They trail only Texas, Tampa Bay and Houston in those rankings.

Fuller was interviewed this week on the Orioles Radio Network for the pregame show and was asked if the coaches have some hitting philosophies that pertain to every O’s hitter?

“Our cornerstones from the DR (Dominican Republic) all the way to the big leagues is control the zone,” said Fuller. “Positive swing decisions. If you do that it is going to lead to constant contact and if you have contact on pitches in zone, it’s going to lead to damage. And those extra-base hits and game-changing swings.

Jack Flaherty is ready to make today’s start, his fourth since joining the Orioles in a deadline trade with the Cardinals.

Flaherty was pushed back after experiencing general soreness and saying he didn’t “bounce back” from his last start and ensuing workout. He’s allowed 10 runs and 10 hits in eight innings in his last two starts.

Today’s opponent seems to suit him. He’s registered a 1.90 ERA and 0.887 WHIP in four career starts against the Rockies in 23 2/3 innings.

Gunnar Henderson, with an 11-game hitting streak, is the third baseman today. Jordan Westburg is playing second.

Cedric Mullins is batting eighth. Adley Rutschman is the designated hitter and remains atop the order.
