Jorge Mateo isn’t in tonight’s lineup, as the Orioles begin their homestand with three games against the Tigers. Mateo left Wednesday's game in Washington with hip discomfort. However, the team didn’t announce a roster move.

Gunnar Henderson is playing shortstop and Ramón Urías is at third base.

Terrin Vavra is in right field and Anthony Santander is the designated hitter.

Ryan Mountcastle has collected 20 of the Orioles’ 96 RBIs - 20.8 percent that ranks as the third highest in the majors, per STATS.

Adley Rutschman’s 17 walks lead the American League. Henderson has drawn 15 to tie for second.

Grayson Rodriguez makes his Camden Yards debut tonight, sans the gas cans in the stands.

Rodriguez remains in the rotation while Kyle Bradish is on the injured list with a bruised right foot, and he could stay depending on his results and how the Orioles could create room for him. Bradish is expected to begin an injury rehab assignment this week.

The Orioles called up Rodriguez to make Wednesday’s start in Texas, and he retired 13 of the last 15 batters after a two-run first inning. He kept the Rangers scoreless over the last four innings.

Adley Rutschman, who’s homered in back-to-back games for the first time in his career, is catching again tonight. James McCann is the designated hitter.

Austin Hays is leading off, with Cedric Mullins moved down to ninth.

The Orioles begin a new series at home tonight, with the Athletics sending the first of three consecutive left-handed starters to the mound.

Ryan McKenna is starting in right field against Oakland’s JP Sears. Anthony Santander is the designated hitter, with Austin Hays in left.

Gunnar Henderson is out of the lineup. Ramón Urías is the third baseman.

Adley Rutschman is catching. He's batting .389/.476/.556 (14-for-36) with two home runs, six RBIs and six walks in nine games. Still no doubles.

Kyle Gibson has won his first two starts while allowing six runs and 12 hits with one walk in 12 innings. He’s 5-3 with a 4.05 ERA in 10 career starts against the Athletics.

BOSTON – Orioles manager Brandon Hyde posted his first lineup of the 2023 season with Ramón Urías and Adam Frazier in the infield and Gunnar Henderson serving as designated hitter.

Kyle Stowers is the odd man out, beginning the game on the bench while the Red Sox start right-hander Corey Kluber.

Urías is playing third base, Austin Hays is in right field and Anthony Santander is in left – in front of the Green Monster.

Asked in the dugout this morning about starting Urías at third, Hyde said, “Well, I’ve got Kyle Gibson on the mound and Urías won the Gold Glove at third base last year and Jorge Mateo should have won the Gold Glove at shortstop, so I feel pretty good about the left side of our infield. Obviously, I want Gunnar’s bat in the lineup.

“These guys are going to move around quite a bit. When we face (Chris) Sale, it’s going to be different, when we face (Tanner) Houck, it’s going to be different. So, it’s going to be pretty much starting-pitcher-against-us-dependent, with also who we have on the mound. But all these guys are going to play.”

BOSTON – The Orioles set their 26-man roster with the anticipated moves on the injured list and a late pivot in the bullpen.

Logan Gillaspie and Mike Baumann made the club, and Joey Krehbiel was optioned to Triple-A Norfolk.

Krehbiel broke camp with the team and spent most of the season on the active roster before slumping over the second half and being optioned in September. He had poor numbers this spring after two exhibition appearances but got on a roll with six straight scoreless and hitless outings, and he seemed like a safe bet to travel north.

Baumann was switched to a short-inning role and thrived with five consecutive scoreless appearances. Gillaspie pitched in seven games and allowed an unearned run with two walks and 10 strikeouts in seven innings.

The Orioles placed catcher James McCann on the 10-day injured list, pitchers Dillon Tate and Mychal Givens on the 15-day IL and John Means on the 60-day IL. Catcher Anthony Bemboom’s contract was selected, giving him two Opening Day roster berths in a row.

SARASOTA, Fla. – Dean Kremer will break camp next week as the No. 2 starter in the Orioles rotation, giving him the April 1 assignment in Boston.

Manager Brandon Hyde provided the information this afternoon but wasn’t ready to go further down the line. A few crumbs for the hungry media.

Kremer is starting Monday’s final exhibition game against the Cardinals in Sarasota, one day after Kyle Bradish faces the Phillies. However, Kremer is moving ahead of Bradish to begin the regular season.

Kyle Gibson is the Opening Day starter for the second time in his career. The club confirmed it this morning.

Kremer has allowed five runs in 14 innings this spring, all on solo home runs. He’s walked two batters and struck out nine.

BRADENTON, Fla. – The Orioles have taken the short ride north for their latest road game, taking on the Pittsburgh Pirates. The Orioles (7-9-2) split two games on Monday, beating Detroit 11-7 at home and losing to Atlanta 6-5 in North Port in a game that was shortened to seven innings by rain.

The Orioles hit eight homers yesterday, six in Sarasota and two in North Port. They have scored 67 runs the past 10 games. 

Orioles closer Félix Bautista will make his long-awaiting spring debut today and is scheduled to pitch the first inning after being held out of games to this point. He has thrown several bullpen sessions and checked all the boxes he needed to get to this point. Now the Orioles hope the final two weeks plus will be enough time for him to be ready for Opening Day and they are confident he will be. It’s a nice step for him today here in Bradenton.

Right-hander Tyler Wells (0-1, 7.71 ERA) is expected to follow Bautista to the mound this afternoon at LECOM Park. Wells has allowed four runs and seven hits in 4 2/3 innings. He last pitched last Thursday in Clearwater against the Phillies allowing one run over 2 2/3 innings. Bruce Zimmermann is also scheduled to pitch for the Orioles.

Terrin Vavra, who is batting .474 (9-for-19) is leading off today and playing second base. Adley Rutschman hits second and will catch. Heston Kjerstad, who hit his third homer Monday against Atlanta, will bat eighth and play in right field and Colton Cowser hits ninth and plays in center.

SARASOTA, Fla. – The Orioles announced today the passing of Luis Andrés Ortiz Soriano, a 20-year-old minor league player from Santo Domingo, Dominican Republic. 

A team statement read: "Our hearts are heavy today as we mourn the passing of minor league pitcher Luis Andrés Ortiz Soriano. Luis was an inspiration to all who knew him, especially as he courageously battled cancer. Our hearts go out to his family and friends."

The young man did not have any stats for the 2022 season. In 2021 in the Rookie-level Florida Complex League he went 1-2 with a 5.52 ERA in 14 2/3 innings.

Manager Brandon Hyde passed along his thoughts to start his pregame press update.

"Want to pass on condolences to the Luis Ortiz family. Sad news last night. From all of us here - our major league staff and players - we want to give our condolences to the Ortiz family," he said. 

SARASOTA, Fla. – Orioles manager Brandon Hyde provided some significant health and workout updates this morning, rattling off the morning advancements from a sheet of paper.

Got to keep it straight, and there were quite a few.

Left-hander DL Hall, who’s recovered from the discomfort in his lower back, completed a bullpen session today. Hyde said it “went well,” and Hall will throw live batting practice in a few days.

Closer Félix Bautista, who’s been restricted to bullpens while receiving treatments on his left knee and working to strengthen his right shoulder, also will threw live BP in the next few days.

Left-hander Nick Vespi, who underwent hernia surgery in January, will pitch in a simulated game later this week. Vespi remains confident that he’ll be ready for Opening Day if the Orioles want to bring him north.

SARASOTA, Fla. – Colton Cowser is starting in center field today against the Pirates, and Adam Rutschman is serving as the designated hitter.

Cowser is 2-for-11 with one home run, seven walks, six strikeouts and six runs scored.

Adam Frazier moves up to the leadoff spot.

Ryan Mountcastle is the first baseman, Ramón Urías is playing third base, Jorge Mateo is the shortstop and Austin Hays is in left field. An infield alignment that will be repeated at times in 2023, when Gunnar Henderson is on the bench.

Kyle Gibson makes his second spring start, both against the Pirates. The Orioles will extend him to three innings if his pitch count allows it.

SARASOTA, Fla. – Terrin Vavra was supposed to play left field and lead off today against the Phillies. However, he's been scratched from the lineup and replaced by Colton Cowser.

Third baseman Gunnar Henderson is leading off. Cowser is batting eighth.

No reason provided at this time.

Orioles reliever Nick Vespi had his fifth bullpen session yesterday morning, using all of his pitches and totaling 35. He advances next week to one or two live bullpen sessions and should be ready to start appearing in games.

Vespi, who underwent hernia surgery on Jan. 5, remains confident that he’ll be ready for Opening Day if he makes the club.

SARASOTA, Fla. – Anthony Santander said this morning that his left knee is fine, and he’s in the Orioles lineup against the Blue Jays.

Santander was hit Monday by an 85 mph pitch and limped off the field.

Cole Irvin is making his Orioles debut and James McCann is catching him.

Ramón Urías is playing third base and batting cleanup. Adam Frazier is the second baseman. Lewin Díaz is the designated hitter.

Austin Voth and Cionel Pérez will pitch today for the first time.

Gunnar Henderson is the cleanup hitter tonight in the Orioles’ penultimate game of the 2022 season.

The forecast calls for rain all day and night, but that’s the plan.

Jesús Aguilar is the first baseman, with Ryan Mountcastle on the bench. Ryan McKenna is the left fielder and Austin Hays is in right.

Terrin Vavra is starting at second base instead of Rougned Odor.

Mike Baumann is making his fourth start and 13^th appearance. He’s lasted four innings in his two starts since being plugged into the rotation on Sept. 24, throwing 58 and 74 pitches.

The Orioles begin the final series of the 2022 season tonight with the Blue Jays arriving in town.

They won’t have Félix Bautista available in the bullpen. He’s been shut down with lingering soreness in his left knee. A roster move is coming.

Gunnar Henderson is the third baseman tonight and Terrin Vavra is in left field. Kyle Stowers is in right.

Dean Kremer has a 3.17 ERA and 1.257 WHIP in 21 games (20 starts). He’s surrendered only 10 home runs in 119 1/3 innings, though two came in his last start in Boston.

Kremer has allowed six earned runs and seven total in 18 innings against Toronto this season.

The Orioles have lost all four games against the Tigers this season, including last night’s 11-0 rout that left them five behind the Mariners for the last wild card. The White Sox are a half-game behind them.

Tonight’s game feels “must win.”

They all do at this point.

Manager Brandon Hyde has performed a major shakeup of his lineup, moving Gunnar Henderson to the leadoff spot for the first time. Henderson is starting again at third base.

Adley Rutschman is lowered to the cleanup spot for the sixth time. He’s batted second in 47 games, a spot occupied tonight by Ryan Mountcastle.

Ryan Mountcastle returns to the Orioles lineup as the designated hitter for tonight’s series opener against the Tigers at Camden Yards. He missed yesterday’s game in Toronto with a bruised left triceps.

Jesús Aguilar is the first baseman against Tigers left-hander Tyler Alexander.

Cedric Mullins stays in the lineup but moves down to eighth. Austin Hays is leading off.

Gunnar Henderson is batting .328/.388/.557 with six doubles, one triple, two home runs, 12 RBIs and six walks in 17 games and 67 plate appearances. He’s the third baseman tonight.

Adley Rutschman had his 24^th multi-hit game of the season yesterday. He’s registered a .367 on-base percentage, with 31 doubles and 56 walks, in 97 games.

WASHINGTON – The Orioles begin a two-game series tonight against the Nationals with Gunnar Henderson playing third base, Kyle Stowers in left field and Austin Hays in right.

Rougned Odor, who left Sunday’s game with a bruised right hand, is on the bench. Ramón Urías is playing second base.

Anthony Santander is the designated hitter.

Hays had his first multi-hit game Sunday since Aug. 27 in Houston.

Dean Kremer has never faced the Nationals.

The Orioles conclude their four-game series tonight with the Blue Jays by starting Kyle Stowers in left field and using Gunnar Henderson as the designated hitter.

Austin Hays is on the bench.

Tyler Wells was reinstated from the 15-day injured list and gets the start instead of Dean Kremer. This is Wells’ first game with the Orioles since straining his left oblique on July 27.

No word on what happens to Kremer.

Wells has made seven career appearance against Toronto, the first six in relief last summer, and allowed nine runs and 16 hits in 12 2/3 innings. He held the Jays to one run in six innings in a June start at Rogers Centre.

Gunnar Henderson is the Orioles’ designated hitter tonight for the third game of their series against the Blue Jays at Camden Yards.

Henderson played second base and shortstop in yesterday’s doubleheader.

The rest of the lineup should look familiar.

Ramón Urías is the third baseman and Rougned Odor is playing second.

Austin Hays is in left field and Anthony Santander is in right.

The Orioles optioned reliever Rico Garcia after yesterday’s 5-0 loss to the Athletics and recalled Beau Sulser from Triple-A Norfolk. A new arm for the bullpen in today’s makeup doubleheader with the Blue Jays at Camden Yards.

Garcia pitched yesterday and retired all four batters he faced.

Mike Baumann is on the mound for Game 1, his first major league start and 12^th appearance.  He faced the Blue Jays on Sept. 12, 2021 in Baltimore and allowed six runs in three innings. Lourdes Gurriel Jr. hit a two-run homer.

In Baumann’s last three starts with Norfolk, he held opponents to two earned runs and three total over 16 innings.

Gunnar Henderson is playing second base again in Game 1. Jesús Aguilar is the designated hitter.
