Mets relief prospect undergoes internal brace procedure

Mets left-handed relief prospect Nate Lavender underwent a “variation of Tommy John surgery” with an internal brace added to his elbow ligament and will miss the remainder of the 2024 season, president of baseball operations David Stearns announced yesterday, according to Tim Britton of The Athletic.

It’s a tough blow for the Mets and for Lavender, who had a strong chance to make his big league debut this season. The 24-year-old southpaw was the Mets’ 14th-round pick in 2021 but has elevated his stock and pitched quite well in the upper minors.

Last year, Lavender breezed through a brief seven-game look in Double-A — his only career action at that level — allowing just two earned runs while posting a 19-to-3 K/BB ratio in 10 1/3 frames. He quickly moved up to Triple-A Syracuse, where he tossed 44 innings of 3.27 ERA ball with a huge 35.1% strikeout rate, albeit against a 12% walk rate. He opened the 2024 campaign with another seven frames and only three runs allowed in Syracuse, although this year’s 20.6% walk rate in that small sample raised some red flags in the run-up to his placement on the injured list.

In writing up the Mets’ nearly MLB-ready prospects, FanGraphs’ Eric Longenhagen credited Lavender with one of the most deceptive deliveries in all of Minor League Baseball. Longenhagen added that even though Lavender doesn’t throw particularly hard (91 mph average fastball), his heater is so difficult for hitters to track that it alone gives him the potential to be a big league reliever despite less-impressive secondary offerings and below-average command.

Lavender doesn’t turn 25 until January, so he still has plenty of prime years ahead of him. If he can get back to his 2023-24 form, he’ll again be a candidate to make his big league debut at some point next summer. Lavender isn’t on the Mets’ 40-man roster but would be Rule 5-eligible this coming offseason.
