John Joseph Klein: Everything you need to know

The Twins optioned Klein to Triple-A St. Paul on Thursday, Betsy Helfand of the St. Paul Pioneer Press reports. The move comes in order to make room for Yoendrys Gomez, who was acquired by the Twins from the Rays on Wednesday. Klein made one appearance up with the big club on Saturday, in which he tossed a perfect inning against the Blue Jays.

The Twins recalled Klein from Triple-A St. Paul on Saturday, Aaron Gleeman of The Athletic reports. Klein has made seven appearances (six starts) at St. Paul this season, posting a 7.48 ERA and 1.32 WHIP alongside a 24:6 K:BB through 21.2 innings. Although his numbers aren't exactly impressive, the Twins will call upon him to fill the open spot in their bullpen left by Cole Sands' (forearm) move to the injured list Saturday.

The Twins optioned Klein to Triple-A St. Paul on Monday. Klein was one of nine players sent out of big-league camp in the Twins' latest round of roster cuts. Minnesota added the 23-year-old righty to the 40-man roster this offseason after he accrued a 3.98 ERA, 1.25 WHIP and 128:37 K:BB across 106.1 innings between St. Paul and Double-A Wichita in 2025. Klein made 15 of his 31 appearances out of the bullpen last season, but he's been building up as a starter during spring training and is expected to handle a full-time role in the St. Paul rotation in 2026.
