    Rosier was one of the better hitters in the Southern Conference this spring. He was a first team All-Southern Conference selection after he led the league with 75 hits and four triples and was tied for the lead with 59 runs and 51 RBIs. Rosier is listed at 5-foot-10, 184 pounds with a contact-oriented lefthanded swing that works well with his plus running ability. He controlled the zone at a solid rate this spring (10 BB%, 11 K%) and didn’t expand the zone or swing and miss too frequently, and when he got a fastball he almost never missed it. While Rosier did have 12 home runs—mostly to the pull side—he doesn’t look like a big power hitter at the next level. He has a simple setup and swing at the plate, with limited pre-pitch movement and a clean, fluid lefthanded swing. He has the speed to be a solid defensive center fielder and went 17-for-23 (74%) in stolen base attempts.
