The San Francisco Giants traded backup catcher Curt Casali to the Seattle Mariners on Tuesday in exchange for two prospects -- relief pitcher Michael Stryffeler and catcher Andy Thomas.
The Giants also sent injured left-hander Matthew Boyd to Seattle in the deal.
The Mariners also acquired infielder/outfielder Jake Lamb from the Los Angeles Dodgers for cash considerations or a player to be named later.
To make room on their 40-man roster, the Mariners released left-handed pitcher Tommy Milone.
Casali, 33, is currently on the 10-day injured list with a Grade 2 oblique strain. He last played July 4.
It was Casali's second season with the Giants after four with the Tampa Bay Rays (2014-17) and three with the Cincinnati Reds (2018-20). Before his injury, he was batting .231 with four home runs and 14 RBIs across 41 games.
Casali is a lifetime .227 hitter with 46 career home runs, 55 doubles and 145 RBIs over 446 games.
Stryffeler, 26, reached Double-A Arkansas last year and is 4-8 at that level with a 2.17 ERA and 128 strikeouts over 78 2/3 innings in two seasons.
Lamb, 31, signed a minor league deal with the Dodgers in March and was called up in June. He hit .239 with two homers and five doubles in 25 games for the Dodgers. He hit 30 home runs with 105 RBIs in 2017 with the Arizona Diamondbacks, earning an All-Star nod.
Boyd, 31, is 37-62 with a 4.96 ERA in 149 career games (145 starts) across seven major league seasons. He has not pitched for San Francisco this season after undergoing forearm flexor tendon surgery.
Thomas, 24, has appeared in 64 games for High-A Everett this season, batting .264 with 32 RBIs and 33 runs scored.
Milone, 35, was placed on the 15-day injured list with a cervical muscle strain on July 30. He appeared in seven games out of the Mariners' bullpen this season, going 1-1 with a 5.40 ERA.
