Sampson, 25, was claimed off waivers from the Padres before the 2015 campaign. He ended up posting a bounceback year at Triple-A, throwing 82 2/3 innings of 3.38 ERA ball with 8.1 K/9 against 5.0 BB/9 while working mostly as a starter. He struggled in a half-season trial run in the major league rotation, though, allowing 6.54 earned runs per nine over his 52 1/3 frames.
Sampson has dealt with control issues before, and that’s been a concern again early in 2016. Between one Triple-A start and two MLB relief appearances, he’s walked seven batters in 6 1/3 innings pitched. While there probably won’t be much interest in plugging Sampson directly onto a big league roster, he still has some promise as a starter and can be optioned.
