During his first three years at West Virginia, Jeffrey made 36 appearances out of the bullpen and has a career ERA of 5.79. He has 47 strikeouts in 37 innings of work. Jeffrey struggled in 2021, posting a career-worst ERA of 6.75. In 20 innings, he allowed 15 runs on 21 hits. He also struck out 28 while issuing 23 walks.
He was a junior in 2021, so he still has a season of eligibility remaining.
Here’s his scouting report, per Prep Baseball Report:
Jeffrey has the type of raw ingredients scouts look for in a pro pitcher. The Barboursville, W.V. native’s velocity has steadily improved during his Mountaineers tenure — his 90-92 mph fastball as a freshman had climbed into the mid-90s the next year, and he’s pitched at 94-96 mph (T98) with elite late life as West Virginia’s closer in ‘21. The 6-foot, 208-pound right-hander complements his fastball with a curveball that flashes plus and a low-spin changeup, the latter a relatively new addition to his arsenal. Jeffrey’s aggressive mentality on the mound fits well in his current bullpen role, but he also has the raw ingredients to merit consideration as a starter in the pro ranks.
