The 26-year-old Martin began the year with the Braves and posted a 5.40 ERA in 21 1/3 innings there before being traded to Oakland in exchange for an international bonus slot in early July. Martin was hit hard in green and gold, though, yielding 14 runs across nine innings in four appearances (two starts). He does have a much better Triple-A track record, where he’s worked to a 4.02 ERA overall in parts of three seasons. Martin had a 2.88 ERA with the Braves’ Triple-A affiliate before struggling upon a move to the Pacific Coast League. He makes for a Major League ready depth piece for a Mariners team that could lose Hisashi Iwakuma to free agency and has seen both James Paxton and Taijuan Walker struggle with injuries.
The veteran Kensing, 33, has seen just 16 Major League innings since 2009 — 15 1/3 of which came with the Mariners this season. He allowed a 5.87 ERA in his return to the Majors. Kensing was up and down with the Marlins from 2004-09 posting a similar 5.81 ERA in 161 innings.
