2026 Projections
2026 Fantasy Outlook
The undrafted free agent had a mini breakout season at Double-A Wichita last season and could be a late bloomer in his age 24 season. He had a 3.12 ERA and 95:24 K:BB ratio in 80.2 innings at Double-A, but struggled when called up to Triple-A with a 6.66 ERA and 33:13 K:BB in 25.2 innings. He was a bit unlucky at Triple-A with a .373 BABIP as he had a 3.30 FIP. Klein was used as a starter and reliever in the minors last season. He had a strong 10.8 K/9 overall in the minors which could make him a candidate for the major league bullpen at some point this summer. Read Past Outlooks
Moves to Triple-A
The Twins optioned Klein to Triple-A St. Paul on Monday.
Analysis
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.
