What It Means:

The injury occurred on Monday night during an outing against the Texas Rangers that saw Tropeano surrender four runs on three jacks in just two frames. The 25-year-old will likely seek a couple more opinions before making a decision, but the likely outcome in this scenario is Tommy John surgery.

Tropeano ranks 132nd in the majors with a 1.46 nERD. He's sporting a 4.51 SIERA and 22.97 percent strikeout rate through 68 1/3 innings, with both of those numbers representing a decline from his 2015 production. However, his 3.56 ERA is a career-best.
