2026 review

Hayden Juenger was a deep-depth reliever who struggled to miss bats or the strike zone, posting a 9.00 ERA and a 2.00 WHIP in 16.0 IP with a 7.4 K% and a 9.9 BB% over 81 BF across 15 games. His contract was selected by TOR on May 30, he was optioned Jun 4, designated for assignment Jun 23, and optioned by ATH after joining that club, then shuttled between the majors and the minors on Jul 21, Aug 8, Aug 12 and Aug 26. Undrafted in NFBC drafts, he finished 1112th of 1472 in the TDK LABS 5x5 value rank and 545th of 575 relievers. The TDK LABS card read him in early Jun as back-of-the-pen middle relief with no save or hold path, then as bullpen depth after a recall in late Jul, and by early Aug had him running clean in Oakland's fluid pen, still drifting up from long duty with no established save or hold role by late Aug.
