The Seattle Mariners added right-hander Casey Sadler to the active roster Monday and placed outfielder Sam Haggerty on the 10-day injured list with a left forearm strain.
Sadler, 30, who has appeared in 52 games over five seasons, was claimed off waivers from the Chicago Cubs on Saturday. He had a 5.79 ERA in 10 appearances with Chicago this season. He is 5-1 lifetime with a 3.82 ERA with the Pirates, Rays, Dodgers and Cubs going back to 2014.
Haggerty, 26, who was claimed off waivers by the Mariners in January, was batting .260 with one home run and six RBIs for the Mariners in 13 games.
