Winkelman was taken in the 21st round in 2015 and posted a 7-2 record with a 3.93 ERA across two

rookie league levels, alomg with a 10.1 K9 rate. He almost held the same K/9 rate in 2016, but struggled with his control giving up 41 walks over 76 innings. He was progressing nicely in 2016 from LoA to HiA before hitting the DL on June 1st. The lefty spent rehabbing back in the GCL and Short-Season Tri-City before making it back to Hi-A and working from the bullpen. Winkelman whiffed a career-high 10 batters last night. So far, his control troubles are behind him with 21 strikeouts and one walk over 14.1 innings to start the season.
