Via Kirk Bohls, the Yankees have signed second round pick Sam Stafford for $400,000, which is just a touch over-slot. Stafford, a left-hander from Texas, has run his fastball up as high as 96 while showing a power curveball this spring and last summer. He struck out 91 but walked 42 in 81.1 IP with the Longhorns this year. Stafford’s raw stuff is undeniable but he struggles to harness it, so he’s going to have to work on his changeup and overall command to stick as a starter. Here’s some video.
