    A tall, 6-foot-7, 215-pound righthander who’s excelled in the bullpen for St. John’s since his freshman season, Hollowell posted a 1.65 ERA in the Big East in 2017 and followed that up with a 2.16 ERA the next year. This spring, through 33 innings and 18 games as the team’s closer, Hollowell’s ERA has risen to 4.36, but he’s striking out batters at a career-best rate, with 42 strikeouts in 33 innings (11.45 per nine) and 14 walks (3.82). He was better toward the end of the season, and has been showing a fastball in the 93-96 mph range, and shows some feel to spin a breaking ball. Hallowell starts with a slight squat on the mound in his stretch and throws from a high, three-quarter slot with some hooking action in the back. A reliever-only profile limits Hollowell’s ceiling in the draft, but his size and arm strength could make him an interesting Day 2 pick.
