2025 Fantasy Outlook
Acquired from the Blue Jays at the 2023 trade deadline in a deal that sent Jordan Hicks to Toronto, Kloffenstein was added to the Cardinals' 40-man roster last offseason. The big right-hander put together a 2.60 ERA during a six-start stretch from mid-May to mid-June, which earned him his first cup of coffee in the majors. Things then quickly unraveled for Kloffenstein, who got knocked around in his next three starts with Triple-A Memphis before missing the remainder of the season with a shoulder injury. The sinkerballer avoided surgery, but the Cardinals wound up non-tendering him, anyway. Even if Kloffenstein bounces back from a health perspective, a 19.4 percent strikeout rate and 10.9 percent walk rate in the International League doesn't portend to fantasy relevance at the next level.

ANALYSIS
Kloffenstein was placed on Triple-A Memphis' 7-day injured list in late July due to right shoulder discomfort, and the injury was serious enough for him to be sidelined for the rest of the 2024 campaign. He went 4-5 across 17 starts in Triple-A and posted a 4.74 ERA, 1.34 WHIP and 73:41 K:BB across 89.1 innings.

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.

Latest Fantasy Rumors
Option to start Saturday
Kloffenstein could be available to be called up to start Saturday against the Cubs, per Jeff Jones of the Belleville News-Democrat.
ANALYSIS
The 23-year-old made his previous start for Triple-A Memphis over the weekend, potentially lining him up to make his MLB debut on Saturday. Kloffenstein has a 4.84 ERA through nine starts this season, but he's looked better over his past three outings with a 3.00 ERA and 0.89 WHIP over 18 innings.
