Coby Mayo is starting at first base today and Jorge Mateo stays in center field for the Orioles’ final game of the homestand.

Ramón Urías moves up to second in the order.

Ryan O’Hearn is the designated hitter. O’Hearn batted .365/.450/.542 in May and posted a .447 average and .681 slugging percentage on fastballs. He has a 10-game hitting streak (19-for-40) and 17-game on-base streak.

Dylan Carlson is in left field and Heston Kjerstad is in right. Adley Rutschman goes to the bench, giving Maverick Handley the start behind the plate.

Charlie Morton rejoined the rotation and held the Cardinals to two runs in six innings to lower his ERA from 7.68 to 7.09. He’s allowed four runs in 15 1/3 innings in his last four appearances.

Morton is 5-0 with a 2.08 ERA and 0.890 WHIP in five career starts against the White Sox.

Mike Tauchman is 4-for-12 with a home run against Morton. Andrew Benintendi is 7-for-31 with two doubles and two homers.

Right-hander Adrian Houser has made two starts and tossed 12 scoreless innings with only five hits. The White Sox signed him on May 20, five days after the Rangers released him.

The Orioles signed Houser on Aug. 31, 2024 but he didn’t pitch for them. He’s made one career start against them and allowed two runs in 3 2/3 innings.
