Back on prospect radar
Kloffenstein has a 2.31 ERA, 1.11 WHIP and 46 strikeouts in 35 innings across seven starts for Double-A New Hampshire.
ANALYSIS
The 6-foot-5 righty was a prospect of note several years ago before logging a WHIP north of 1.55 in over 100 innings in both 2021 and 2022. However, at 22, Kloffenstein is age-appropriate for Double-A. He has been even more impressive over just his last five starts, during which he has a 1.29 ERA, 0.93 WHIP and 38 strikeouts in 28 innings. His sinker has topped out around 95 mph this year, so there may not be as much upside as his stats indicate, but Kloffenstein's 55.8 percent groundball rate is a strong mark, and he could someday pitch in the middle or back of a big-league rotation.

Jesse Siegel is excited about the start of the minor-league season and has a few notes on some of the more prominent prospects.
Past Fantasy Outlooks
2021
2020
Most top prospects spent the summer at alternate training sites, but Kloffenstein took a road less traveled. He played indy ball in a four-team league in Texas -- the continent's highest level of organized baseball outside of MLB in 2020. At 19, he was the youngest player in the league by four years, often facing Triple-A and Quad-A hitters. His pitching coach was none other than the league's founder, Roger Clemens. He was limited to three-inning stints and logged almost a strikeout per inning while firing scoreless outings in five of his last eight appearances. Perhaps most importantly, Kloffenstein's five-pitch mix is now headlined by a four-seamer that touches 99 mph and a sinker that touches 97. The 6-foot-5, 245-pound righty's slider is a third plus pitch, and he's working on getting his curveball and changeup there as well. Harnessing his command will be his top priority in his full-season debut.
