The Seattle Mariners claimed right-hander Jonathan Hernandez off waivers from the Texas Rangers amid a series of roster transactions on Friday.
Hernandez, 28, went 3-1 with a 5.05 ERA across 26 outings (one start) for Texas this season before being released on Tuesday.
He last pitched on Sunday – his lone start this year – and surrendered five runs on five hits over 2 1/3 innings in a 7-3 road loss to the Toronto Blue Jays.
The fifth-year veteran is 13-8 with a 4.18 career ERA in 124 appearances (three starts), all with the Rangers.
Also on Friday, Seattle placed right-hander Gregory Santos (right biceps inflammation) on the 15-day injured list retroactive to Thursday.
Santos, 24, had allowed four runs in 5 1/3 innings in six appearances out of the bullpen for the Mariners this season.
He exited his latest relief outing with the injury after facing two batters in the eighth inning of Seattle’s 3-2, 10-inning road loss to the Boston Red Sox on Wednesday.
The Mariners also released Brett de Geus on Friday, while fellow right-hander JT Chargois reported to the club after he was acquired in a trade with the Miami Marlins on Tuesday.
de Geus, 26, had a 2.70 ERA over four appearances for Seattle this season. Chargois, 33, posted a 1-0 record with a 1.62 ERA in 15 outings for the Marlins.
