BALTIMORE (Interstat) — Dean Kremer pitched 6 1/3 innings of one-hit ball and the Baltimore Orioles began their final home series of the season with a 6-0 victory over the Tampa Bay Rays on Tuesday night at Oriole Park at Camden Yards.

In a game between clubs already eliminated from postseason contention, Kremer (11-10) was dominant. The right-hander struck out four and hit one batter but walked none in his 30th outing of the year. He continued his mastery over the Rays, improving his lifetime record to 5-1 with a 1.64 ERA across 11 starts against Tampa Bay.

The Orioles (74-83) provided Kremer with early support, scoring two runs in the bottom of the first inning against Rays starter Ryan Pepiot (11-12). Jackson Holliday walked and scored on a sacrifice fly by Gunnar Henderson. Jordan Westburg, who doubled, later scored on a groundout by Tyler O’Neill.

Baltimore added a run in the third inning when Henderson singled home Coby Mayo, who had singled earlier in the frame. The Orioles extended their lead to 4-0 in the fifth. Colton Cowser and Mayo singled consecutively, and Cowser eventually scored on a sacrifice fly by Westburg.

The offense broke the game open in the sixth against Rays reliever Ian Seymour. After two quick outs, Samuel Basallo was hit by a pitch, bringing Cowser to the plate. Cowser connected on a two-run homer, his 16th of the season, to center field to cap the scoring at 6-0.

Kremer’s only hit allowed was a fourth-inning single to Chandler Simpson. He was lifted with one out in the seventh inning after hitting Junior Caminero. The Orioles’ bullpen preserved the shutout, with José Castillo, Yaramil Hiraldo and Colin Selby combining for 2 2/3 innings of one-hit relief.

Pepiot took the loss for the Rays (76-81), allowing three runs on three hits over three innings. He struck out three and walked one. Tampa Bay’s offense mustered just two hits total, with Josh Lowe’s seventh-inning single being their only other baserunner against the Baltimore pitching staff.

The announced attendance was 15,267 for the game, which lasted 2 hours, 29 minutes. The result defied pregame projections, as the Rays had been installed as a -1.5 favorite, and the total score of six runs fell well under the over/under line of 9.

The two teams will continue their three-game series on Wednesday. The Rays will look to even the set before both clubs conclude their 2025 campaigns with road series against American League East rivals over the weekend.
