Sims, 22, has a 6.80 ERA and 54:34 K:BB through 46.1 innings for Triple-A Gwinnett.
Strikeouts aside, Sims has been awful since being promoted. He has allowed 11 home runs in 10 outings. An inability to keep the ball on the ground will only further serve to hurt him as he approaches the big leagues. He has also walked at least three batters in each of the last six games. Sims still has time to right the ship, but he has a ton of kinks to work out.
