Aneury Rodriguez, 24, had a sip of coffee before being sent back down to the minors. In his one and only appearance with the team, Rodriguez allowed 2 hits (both solo shots) in 6 innings of work while striking out 6 and walking 0. We should expect to see him sometime again, but for now he's a victim of numbers.

Enerio Del Rosario, 26, made 15 appearances out of the bullpen for Houston before being outrighted to the minors. He posted a 7.80 ERA across 15 innings of work while showing a lack of control (4.2 BB/9) and an inability to put batters away (4.8 K/9).
