The Rockies announced Monday that they’ve claimed left-hander Antoine Kelly off waivers from the Rangers, who’d previously designated him for assignment. In order to open a spot on the 40-man roster, Colorado designated fellow lefty Josh Rogers for assignment.
Kelly, 24, was a second-round pick by the Brewers in 2019 and went to the Rangers alongside utilityman Mark Mathias in the 2022 deadline deal that sent righty Matt Bush from Texas to Milwaukee. Kelly pitched in the 2022 Futures Game and enjoyed a standout 2023 season split the Rangers’ Double-A and Triple-A bullpens: 57 1/3 innings, 11 saves, 2.04 ERA, 32.1% strikeout rate, 9.3% walk rate.
That promising trajectory has gone off the rails in 2024, however. Kelly has missed significant time with a forearm injury this season and been ineffective when healthy, yielding 17 earned runs in a span of 16 1/3 innings at the Triple-A level. His strikeout rate has dropped considerably, though at 25%, it’s still better than average. However, Kelly has issued nearly as many walks as he has recorded strikeouts, with a glaring 22.9% of his opponents reaching via base on balls. Add in the two batters he’s plunked, and he’s at a combined 24 walks/HBP — the same number of strikeouts he’s yielded this season.
Command troubles — albeit not to this extent — are nothing new for Kelly. Even prior to this season, he’d walked 13% of his career opponents. Last year’s strong K-BB profile represented a significant step forward for the southpaw, and the Rockies will hope they can get him back to that form down the stretch and into future seasons. Kelly is in the first of three minor league option seasons, so the Rox will be able to freely option him not only this year but also in 2025 and 2026 if they keep him on the roster for that long.
The 30-year-old Rogers signed minor league deals with Colorado in each of the past two offseasons. He didn’t pitch for the Rockies in ’23 but has appeared in five games this season, logging 9 1/3 innings out of the bullpen and surrendering seven runs on a dozen hits and two walks with two strikeouts. The Rockies selected Rogers to the MLB roster in late May but placed him on the injured list barely two weeks later, owing to a strain in his left rotator cuff. Rogers was reinstated from the injured list and optioned to Triple-A just yesterday. He’ll now spend up to a week in DFA limbo as he waits to learn whether he’s been traded, claimed by another club, passed through outright waivers or released.
Originally an 11th-round pick by the 2015 Yankees, Rogers went to the Orioles as part of the Zack Britton trade in 2018. He pitched parts of two seasons with the O’s and another two with the Nats after being released and signing a minor league deal in Washington. Overall, he’s pitched 97 1/3 innings in the majors between three teams and yielded a 5.55 ERA with a 10.9% strikeout rate and 5.5% walk rate. He’s pitched 496 innings in Triple-A as well but had similar struggles there: 5.72 ERA, 15% strikeout rate, 6.6% walk rate.
