2026 review

Kenley Jansen closed for DET all season, saving 22 games with a 3.20 ERA and 1.04 WHIP in 45.0 IP over 50 games, striking out a 28.3 K% against a 12.8 BB% over 180 BF, with 6 BS along the way. He went on the 15-day IL May 28 with pelvic inflammation, took a rehab assignment Jun 10, and was activated Jun 12 after missing 15 regular-season days. Drafted at NFBC ADP rank 118, he finished 194th of 1472 in the TDK LABS 5x5 value rank, 76 spots below, and 26th of 575 relief pitchers. His 3.20 ERA ran 0.40 below his 3.60 xERA over 180 BF, and his ERA improved after the IL stint, 4.80 in 15.0 IP before it against 2.40 in 30.0 IP after he came back. The TDK LABS card had its doubts early: in early May it flagged trouble beneath the closer role with blown saves and a high ERA, but by early Jul it described the role as consolidating after a clean ninth, and by late Aug it still had the closer role as his.
