The 22-year-old had a rough stint with Triple-A Gwinnett, but his 2.67 ERA and 10.0 K/9 at the Double-A level opened some eyes in the organization, leading Atlanta to protect him from the Rule 5 draft. Sims' nasty fastball/curveball combination could allow him to dominate in a high-leverage role if the Braves decide to pull the plug on developing him as a starter in 2017.
The 22-year-old was having a rough time with Triple-A Gwinnett, posting a 2-6 record with a 7.56 ERA in 50 innings of work. He had given up 37 walks and 12 home runs during his time with the club, and was transferred back to Mississippi as Chris Ellis took his place. Sims will have more chances to compete at the next level, but for now he will have to improve upon his command and inability to get opposing hitters to hit the ball on the ground.
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.
Sims, 22, has a 4.91 ERA and 25:8 K:BB through 22 innings since being promoted to Triple-A
Sims has been snake-bitten by the home run ball at this level, surrendering four home runs in four starts. Still, he has been otherwise effective, including averaging more than a strikeout per inning.
Sims dominated at Double-A to open the year, striking out 26 batters while allowing just seven hits (albeit with 10 walks) over 14.2 innings. In his Triple-A start, he allowed two runs over five innings, giving up three hits and four walks while striking out four. Unfortunately for Sims, the walks are a feature and not a bug, so enthusiasm for his strikeout potential has to be tempered some.
