Rex Brothers, LHP, Rockies (Short-Season Tri-City)
Attached to many teams with late first-round picks back in June, Brothers ended up falling just outside of the first round despite outstanding velocity for a southpaw, going 34th overall to Colorado. Recently signed to a $969,000 bonus, Brothers made his pro debut over the weekend, pitching one-two-three innings with a pair of strikeouts on both Friday and Sunday. His heat sat in the low 90s, and he pushed his fastball up to 96 mph at times. He also features a plus slider, and if he remains in a relief role, as expected, he could move up very quickly.
