The Blue Jays recalled Klein from Triple-A Buffalo on Friday.
Klein has spent nearly all of the 2026 campaign at the Triple-A level, holding a 6.36 ERA and 95:51 K:BB over 86.1 innings. The 24-year-old will be available to absorb some innings this weekend as the Blue Jays close out the regular season.

The Blue Jays acquired Klein, along with Dasan Hill and Dameury Pena from Minnesota in exchange for Jeff Hoffman on Monday, Mark Feinsand of MLB.com reports.
Klein appeared in three games for Minnesota this season, but spent most of his time with Triple-A St. Paul. In Triple-A, the 24-year-old has recorded a 5.91 ERA, 1.52 WHIP and 74:34 K:BB in 64 innings this season. The right-hander will most likely report to Triple-A Buffalo as he moves over to his new organization.

The Twins optioned Klein to Triple-A St. Paul on Sunday.
The right-hander was called up Saturday and will return to St. Paul after firing two scoreless frames against Pittsburgh. Across two stints in the majors this year, Klein has given up two earned runs with 2:4 K:BB in three appearances (4.1 innings).

The Twins recalled Klein from Triple-A St. Paul on Saturday.
Klein has conceded two earned runs in just 2.1 innings with the Twins this season, but since being optioned to Triple-A on May 7, he's posted a 3.65 ERA and 0.89 WHIP with a 16:5 K:BB across 12.1 innings. Now back with the big club, he'll presumably work in a multi-inning role out of the bullpen, replacing Simeon Woods Richardson, who was DFA'd in a corresponding move.

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 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.
