Winn allowed one run on two hits and five walks while striking out one over four innings for Low-A Hickory on Tuesday.
The one run allowed was the fewest in three starts for Winn but he has experienced wayward control. The 19-year-old right-hander has walked 10 batters over 8.1 innings. The Rangers' first-round pick (15th overall) in 2018 has skipped short-season ball for a more advanced placement.
