2026 review

Luke Weaver spent the year as an effective setup arm whose control stood out: a 2.69 ERA and 0.96 WHIP in 60.1 IP with a 27.3 K% and a 6.7 BB% over 238 BF, working to 4 W, 1 L, 1 SV, 24 HLD and 4 BS across 60 games. He was traded from NYM to PIT on Aug 3, and his 14.5 SwStr% over 904 pitches was the 38th highest of 517 pitchers with 100+ BF. Drafted at NFBC ADP rank 456, he finished 251st of 1472 in the TDK LABS 5x5 value rank, 205 spots above, and 44th of 575 relief pitchers. His ERA ran 0.39 below his 3.08 xERA over 238 BF, and he split right-handers well at .129/.205/.178 over 112 PA against a tougher .252/.304/.426 over 126 PA from lefties. His best month was May at a 0.00 ERA in 12.2 IP against a 7.20 ERA in 10.0 IP in Apr. The TDK LABS card had him penciled as a tier-2 setup arm behind another reliever in early May with the ninth-inning picture unsettled, then by early Aug it had him picking up a closer role in a fresh committee after the trade, and by late Sep it was calling him a setup arm on a run of consecutive holds.
