Mariners call up Michael Arroyo as MLB roster moves continue

The Seattle Mariners have promoted infielder Michael Arroyo to the major league roster. Arroyo, the 35th player born in Colombia to reach the MLB, started at second base and recorded an 0-for-3 performance with a strikeout in his debut against the Athletics. Elsewhere, Bryan Woo delivered eight scoreless innings with nine strikeouts in a recent start for Seattle. Across the league, the Dodgers expect Shohei Ohtani to return to the lineup this Monday, though he is unlikely to pitch again during the regular season. Cooper Hjerpe made his major league debut for the St. Louis Cardinals, recording four perfect innings. Additional roster updates include the Dodgers placing catcher Dalton Rushing on the 10-day injured list and the Orioles losing Luis Robert Jr. to the injured list shortly after his waiver claim.
