Ryan McKenna doesn’t step up to the plate with the intent to hit a home run. He has the power but isn’t going to flex.

When McKenna’s fly ball in the eighth inning of Tuesday night’s game cleared the vaunted left field wall, he broke a tie – another temporary lead – and delivered the first go-ahead hit of his career.

The home run was his third in 288 plate appearances, and his first since last September.

The ball left McKenna’s bat at 103 mph. The 396 feet were sufficient.

Was he confident that it would land in the seats?

The Orioles discussed potential bullpen moves after last night’s wild 10-9, 10-inning victory over the Rangers and decided upon Beau Sulser, who’s been recalled from Triple-A Norfolk. He was on the taxi squad during the last road trip.

Left-hander Nick Vespi was optioned to Norfolk after last night’s game. Vespi was charged with six runs in one-third of an inning on June 29 in Seattle, tossed 1 1/3 scoreless with three strikeouts Monday against the Rangers, and served up a game-tying three-run homer last night to Norfolk native Nathaniel Lowe in the eighth.

Sulser has made one appearance with the Orioles and allowed two runs and seven hits in three innings. He has a 3.20 ERA in seven games with the Tides.

Marcos Diplán appeared to be a candidate to rejoin the Orioles, but they designated him for assignment and claimed left-hander Kirk McCarty off waivers from the Guardians. McCarty has been optioned to Norfolk.

The 40-man roster remains at full capacity.

CHICAGO – Spenser Watkins is back in the rotation and reliever Marcos Diplán is optioned without pitching yesterday.

The Orioles also recalled infielder Jonathan Araúz from Triple-A Norfolk and optioned infielder Rylan Bannon, who didn’t appear in a game in his second stint with the team.

Watkins has been recalled as Kyle Bradish’s replacement. Bradish went on the 15-day injured list yesterday with right shoulder inflammation.

The Orioles simply had to activate Watkins from the taxi squad.

Watkins hasn’t started for the Orioles since failing to retire any of three Tampa Bay batters on May 22 and leaving with a bruised right elbow – the product of a line drive from Ji-Man Choi.

CHICAGO – Kyle Bradish began feeling some discomfort in his right shoulder a few days ago after his bullpen session, and the Orioles had to put him on the 15-day injured list this afternoon, with fingers crossed that it isn’t an extended absence.

Bradish has made 10 starts in his first major league season and posted a 7.38 ERA and 1.770 WHIP. He hasn’t finished five innings in his last five outings, unable to recapture the form that enabled him to strike out 11 batters with no walks in seven innings in St. Louis.

“We’re doing this out of precaution,” manager Brandon Hyde said. “We’re hoping it’s just going to be a couple weeks, but he does have some fatigue in there. We’ll take a couple weeks to get some treatment, be with Brian (Ebel) and the guys in the training room, and hopefully he just misses a couple weeks.”

The reasons behind Bradish’s shoulder inflammation aren’t clear. Hyde can’t blame the high-stress innings in the majors or any other excuse.

“Tough to speculate,” Hyde said. “I think there’s a lot of things going on around the league, but the intensity level up here is definitely different. It’s hard to put my finger on why his shoulder is a little bit sore. But hopefully it’s just a little bit of a hiccup and he’s back in a couple weeks.”

CHICAGO – The Orioles placed rookie starter Kyle Bradish on the 15-day injured list today and recalled reliever Marcos Diplán from Triple-A Norfolk.

The move is retroactive to Tuesday.

Bradish was scheduled to start tonight and then pushed back to Saturday. Now he’s off the active roster after posting a 7.38 ERA and 1.770 WHIP in 10 games.

The last start against the Rays ended with Bradish allowing six runs and a career-high 11 hits in 4 1/3 innings. He hasn’t completed five innings in his last five outings.

The rotation already underwent a change last week with Bruce Zimmermann optioned to Norfolk. A starter is needed for Saturday and Spenser Watkins is a logical choice because he’s on the taxi squad and threw only one inning Wednesday in Lehigh Valley to keep him available.

Can you build a bullpen and get significant contributions from other teams' castoffs and have that bullpen perform about as well as any in baseball? So far, for the Orioles, that answer is yes.

Over time we will see if this bullpen can keep up its impressive start and how the ‘pen will hold up when having to cover so many innings. But if we gave a 49-game grade, how could they get anything other than an A?

Even in losing 12-2 Sunday, right-hander Cody Sedlock helped preserve the bullpen for tonight by pitching three innings plus in his major league debut. He and Marcos Diplán combined to give up six runs, but no other pitchers were needed on a day when starter Bruce Zimmermann allowed five homers and pitched just four innings.

The O’s ‘pen, in having this big year, has been a real key in the team’s overall improvement and ability to beat good teams and win some close games. The Orioles seem to be slowly getting better at winning those close games as the year goes on.

Through Saturday’s games, the Baltimore 'pen had an ERA of 3.00 to rank second behind Houston at 2.53. And the O’s bullpen compiled a 2.61 ERA in May, also second to the Astros, whose relievers are at 1.94 for the month.

NEW YORK – The Orioles are making massive changes to their pitching staff heading into tonight’s series opener at Yankee Stadium.

Right-handers Marcos Diplán, Logan Gillaspie and Beau Sulser have been recalled from Triple-A Norfolk, with pitcher Mike Baumann and infielder Tyler Nevin optioned after yesterday’s game and Spenser Watkins placed on the 15-day injured list with a right elbow contusion.

Watkins was hit by a 106 mph line drive off Ji-Man Choi’s bat in the first inning of yesterday’s game.

Gillaspie is able to return early from the minors because he’s replacing an injured player. He’s tossed 3 2/3 scoreless innings in two appearances.

Sulser, wearing No. 67, made his major league debut this season with the Pirates and appeared in four games before the Orioles claimed him off waivers May 14. He’s the brother of former Orioles reliever Cole Sulser.
