Here's MLB Pipeline's roundup of the top prospect performances in the Minor Leagues on Thursday.
:: Complete prospect coverage ::
It may have been the first start of the season for Triston McKenzie, but the 20-year-old right-hander looked to be in midseason form as he led Double-A Akron to a 7-4 win over New Hampshire.
The Indians' No. 2 prospect (No. 21 overall) started the season on the disabled list after experiencing forearm soreness during Spring Training. However, on Thursday he was ready to go and showed why he's one of the top pitching prospects in baseball as he threw five scoreless innings.
McKenzie, who threw 43 of his 63 pitches for strikes, walked two, struck out four and gave up just one hit -- a single to lead off the fifth -- in the outing.
