The Seattle Mariners placed right-hander Jackson Kowar on the 60-day injured list Sunday because of a right ulnar collateral ligament tear.
The team announced last week that Kowar, 27, was meeting with doctors on Friday after experiencing soreness in his throwing arm.
The Mariners obtained Kowar and minor league right-hander Cole Phillips from the Atlanta Braves in a Dec. 3 trade for outfielder Jarred Kelenic, left-hander Marco Gonzalez and first baseman Evan White.
The Braves acquired Kowar from the Kansas City Royals less than a month earlier, on Nov. 17, for right-hander Kyle Wright.
The Royals selected Kowar in the first round, 33rd overall, in the 2018 MLB Draft out of Florida. Kowar was 2-6 with a 9.12 ERA, 75 strikeouts and 51 walks in 74 innings over 39 games (eight starts) from 2021-23.
