Cardinals to recall intriguing pitching prospect for MLB debut
The Cardinals will recall righty Adam Kloffenstein before Thursday evening’s game with the Giants at Birmingham’s Rickwood Field, as first reported by Ari Alexander of KPRC-2. It’ll be the 23-year-old’s major league debut. Kloffenstein is already on the 40-man roster. He would have been eligible for the Rule 5 draft last winter, so St. Louis selected his contract in November.
Kloffenstein was a second-round pick of the Blue Jays out of a Texas high school back in 2018. He was pitching in Double-A last summer when the Jays packaged him alongside Sem Robberse in the deal to plug Jordan Hicks into the back of the bullpen. St. Louis prioritized upper-minors pitching in their deadline sw
The Cards immediately pushed Kloffenstein to Triple-A Memphis. He finished last season with nine outings there, tossing 39 frames of 3.00 ERA ball. He has worked out of the Memphis rotation this year with similar results. Kloffenstein carries a 3.97 ERA over 77 innings. His 21.9% strikeout rate and 9.4% walk percentage are pedestrian, but he’s getting ground-balls at a solid 48% clip.
Andre Pallante gets the start on Thursday with Miles Mikolas and Sonny Gray closing out the weekend series. (The teams are off on Friday to travel from Birmingham to St. Louis for the final two games of the set.) That suggests Kloffenstein could get a look from the bullpen for his first MLB work. He has started all but two of the appearances in his minor league career. Baseball America ranked him 28th in the St. Louis system over the winter, writing that he profiles as a depth starter or grounder-oriented long reliever.
