Karczewski has a projectable frame at 6-foot-3, 175-pounds, and works from a high slot with a clean arm swing. The right-hander sat 83-84, but it’s not hard to dream that there is more velocity to come in the future. His curveball has good 12/6 downer shape at 68-70. The two-way player and right-handed hitter also had a couple of hits on balls he squared up to the pull side.
