Back with M's The Mariners recalled Kowar from Triple-A Tacoma on Thursday.

Impact Since being optioned to Triple-A in mid-June, Kowar has given up six runs (three earned) over nine innings while striking out 12 batters and walking seven. He owns a 2.08 ERA through 8.2 frames with the Mariners this year, but his career 8.38 ERA will keep him limited to a low-leverage role in Seattle's bullpen. Brandyn Garcia was optioned to Tacoma in a corresponding move.
