He's expected to be an immediate impact player. Likely weekend starter even before Pallette went down. A few blurbs on him from the D1 preview:
Top Newcomer: Take your pick between blue-chip freshmen Stovall and Smith or big-ticket D-I transfers Jace Bohrofen, Chris Lanzilli and Michael Turner. All of them will be huge difference makers. But we already included Stovall in the “star power” section, so let’s give the nod to Smith, a funky low-slot lefty with supreme feel for pitching. Even as a true freshman, Smith might have the best present combination of stuff and pitchability on the entire staff, and we expect him to be a fixture in the rotation right away.
From the Fall
The fourth top contender for a starting job is true freshman Hagen Smith, the other crown jewel of this year’s recruiting class along with Stovall. Hobbs and Van Horn couldn’t stop raving about Smith, and I saw why in Monday’s scrimmage, when he breezed through three scoreless innings. A loose, athletic low three-quarters lefthander with advanced feel for pitching, Smith carved up the zone at 91-93 mph with heavy sink, a sharp slider at 79-82 that he commands very well, and a very good 83-86 changeup with fade and sink that he’ll throw against lefties as well as righties. Though he’s only a freshman and he has yet to proven himself at the D-I level, Smith might have the best combination of stuff and pitchability on the entire staff, and he’s going to be a big star — sooner rather than later. And his high school track record in Texas is loud: he threw seven no-hitters in his career at Bullard High School.
