Logan Bawcom

Bawcom joined the Mariners' organization in 2012 as part of the Brandon League trade with the Dodgers and turned heads in 2013 with 64 strikeouts in 65 innings. He took a major step back last year, though, as his K/9 dropped to 6.4 while his K:BB stood at 32:25 in 45.2 innings at Triple-A Tacoma. His ERA was 4.93, but his FIP was even worse at 5.24. Nevertheless, the Mariners don't have many reliever prospects on the 40-man roster, and Bawcom, who has a mid-90s fastball with a strong slider, could get a call to Seattle this season if the need arises.
