Bawcom was acquired by the Mariners, along with outfielder Leon Landry, in 2012 in a midseason trade with the Dodgers for Brandon League. The Texas native was originally drafted by the Dodgers in the 17th round of the 2010 First-Year Player Draft and has gone 19-16 with a 3.20 ERA in 212 outings over five Minor League seasons.
He was designated for assignment last week to open a spot on Seattle's 40-man roster for outfielder Justin Ruggiano, who was acquired in a trade from the Cubs.
