Michael Soroka's third promotion to Atlanta this season in his comeback from two Achilles tendon injuries has led to more health concerns for the right-hander.
Tyler O'Neill and Nolan Gorman hit two-run homers to spoil Soroka's return to Atlanta, and the St. Louis Cardinals held on to beat the Braves 10-6 on Tuesday night.
After the game, Braves manager Brian Snitker said Soroka (2-2) is headed to the injured list after experiencing numbness in his fingers. Soroka, who was recalled from Triple-A Gwinnett for the start, lasted only three innings and allowed five runs on four hits, including the two homers.
Snitker said he asked Soroka about the numbness and the right-hander said he "didn't really know when it started."
Added Snitker: "I think it's probably a big deal."
Soroka, an All-Star in 2019 and Atlanta's opening day starter in 2020, has spent most of this season in the minors as he tries to make a comeback from Achilles tendon injuries in 2020 and 2021.
Though he issued only one walk in his abbreviated start, Soroka's control issues were a problem.
"Overall, he just didn't command the strike zone real good," Snitker said.
Soroka, who was being evaluated after the game, wasn't available for comment.
