The Seattle Mariners recalled infielder Leo Rivas from Triple-A Tacoma on Tuesday to take the roster spot of veteran infielder Jorge Polanco, who was placed on the paternity list.

Rivas, 27, made his major league debut last year with Seattle and amassed a .233 batting average with eight RBIs and three stolen bases in 43 games. He opened this season with two home runs and four RBIs in three games for Tacoma.

Polanco, 31, has enjoyed a quick start to the 2025 season as he carries four-game hitting streak into his paternity-list stay.

The switch hitter cracked a go-ahead two-run homer in the eighth inning on Opening Day, and he owns a .400/.400/.600 slash line through 16 plate appearances as the Mariners’ primary third baseman.

Miles Mastrobuoni started at third base and batted eighth for Seattle on Tuesday night against the visiting Detroit Tigers. Mastrobuoni entered the game 1-for-1 on the season, as he had a pinch single against the Athletics on Friday.
