Astros southpaw Brandon Walter underwent UCL reconstruction surgery yesterday, the team informed reporters (including Chandler Rome of The Athletic). Meanwhile, Ari Alexander reports that southpaw John Rooney had a procedure to remove bone spurs and address tennis elbow.
Houston had announced a couple weeks back that both pitchers were going under the knife. They didn’t provide specifics at the time beyond calling each a season-ending elbow procedure. The news is obviously much worse for Walter, who’ll miss all of next season. Rooney’s surgery is less significant and it doesn’t seem out of the question that he’ll be available for Spring Training.
Walter, 29, had proven a nice pickup on a minor league deal last August. Houston selected his contract at the end of May. Walter picked up nine starts for an injury-riddled rotation. He tossed a quality start in six of those outings, working to a 3.35 earned run average across 53 2/3 innings overall. The former Red Sox prospect punched out a quarter of batters faced against a pristine 1.9% walk rate. Walter overcame pedestrian velocity to get chases and whiffs at slightly above-average rates.
Unfortunately, the injury bug struck again for the 29-year-old. Walter missed the entire 2024 season after suffering a rotator cuff injury while pitching in minor league camp with Boston. That led the Red Sox to release him, paving the way for him to land in Houston. Walter probably showed enough for the Astros to keep him on the 40-man roster throughout the upcoming offseason. They’d be able to place him back on the 60-day injured list at the beginning of Spring Training.
Rooney may have a tougher time sticking on the roster. He was on a minor league deal with the Marlins when Houston acquired him at the beginning of August. Rooney came up for his big league debut in late August. He tossed 1 1/3 innings of one-run ball before suffering the season-ending injury. The 28-year-old reliever combined for a 2.56 ERA over 38 2/3 Triple-A frames this year.
He’s just acting….
No, no…that’s Walter Brennan….
