Antonio Senzatela targeting May return from ACL surgery

Rockies starter Antonio Senzatela had an unfortunate end to his 2022 season. The right-hander tore the ACL in his left knee while attempting to track down a grounder in mid-August. He underwent surgery that initially came with a six-to-eight month recovery timetable.

Six months removed from the injury, it seems things are mostly on the expected course. Danielle Allentuck of the Denver Gazette writes the Rockies anticipate Senzatela returning to a big league mound in May. He’s certain to start the season on the 15-day injured list but seems unlikely to land on the 60-day IL barring a setback.

Once healthy, Senzatela will surely reclaim his old spot in the rotation. Colorado placed a strong show of faith in the Venezuelan-born hurler last offseason, inking him to a five-year, $50.5M extension. The deal, which bought out as many as four free agent years, kept him around on the heels of a 4.42 ERA showing over 28 starts in 2021. That was respectable production for a pitcher who spends half his outings at Coors Field, his second consecutive season of solid output towards the middle or back of a starting staff.

Last year proved more challenging even before the injury. Senzatela gave up a little more than five earned runs per nine innings across 19 starts. His 49.4% ground-ball rate was down a couple percentage points from his peak, albeit still better than average. Senzatela’s strong command and pitch-to-contact profile mostly remained intact, but last year’s .383 batting average on balls in play against him inflated his ERA despite generally similar underlying marks to seasons past.

The Rockies are hoping for bounceback years from the bulk of their rotation after doing very little over the offseason. Germán Márquez and Kyle Freeland each posted down seasons last year. Senzatela is typically their #3 rotation option, though that’ll probably fall to José Ureña to open the season. The back of the rotation spots are especially uncertain.

Left-hander Austin Gomber looks to have the inside track on of those jobs. Allentuck writes that Colorado will move Gomber back into the rotation mix after kicking him to the bullpen for the second half of last season. The 28-year-old southpaw’s results weren’t much different in either role. Gomber posted a 5.75 ERA with an 18% strikeout rate as a starter and a 5.11 ERA with a 17.8% strikeout percentage out of the bullpen.

Given Colorado’s need for innings at the back of the rotation, moving Gomber back into a starting role makes sense. He’d pitched reasonably well over 23 starts in 2021, posting a 4.53 ERA with a solid 23.2% strikeout rate over his first 115 1/3 innings in Colorado. That’s the only season in which Gomber has started at least 20 big league games, though he still has a more established track record than other back-end candidates like Connor Seabold, Ryan Feltner, Ryan Rolison and Peter Lambert.
