The Mariners have released righty Seth Frankoff, as per a team press release. Frankoff was granted his release so he could pursue an opportunity with a team in South Korea.
Frankoff made his MLB debut last season, appearing in one game for the Cubs and tossing two innings. Chicago designated Frankoff for assignment in September, only for Seattle to claim him off waivers a few days later.
Originally a 27th-round pick for the Athletics in the 2010 draft, Frankoff posted a 3.80 ERA, 8.9 K/9 and 2.69 K/BB rate over 637 career minor league innings with the A’s, Dodgers, and Cubs. The 29-year-old has begun working as a starter over the last two seasons after pitching exclusively out of the bullpen from 2013-15.
