The Seattle Mariners, Texas Rangers and San Francisco Giants have added players on waiver claims.
The Giants got outfielder Mike Gerber from Detroit. The 26-year-old made his big league debut last season and went 4 for 42 in 18 games for the Tigers.
The Mariners made the most interesting move, taking Kaleb Cowart from the Los Angeles Angels and announcing him as an infielder and right-handed pitcher.
A prep star on the mound and at the plate, the 26-year-old Cowart has not pitched since the Angels drafted in the first round in 2010. He hit .134 with 10 RBIs in 47 games with Los Angeles last season.
Texas acquired infielder Carlos Asuaje after he was cut by San Diego last week. The 27-year-old hit .240 in parts of the last three seasons with the Padres, and did well in the field at second base.
