Houston Astros pitcher Lance McCullers will undergo Tommy John surgery and miss all of the 2019 season.
Bob Nightengale of USA Today reported the news.
McCullers, 25, was injured in August while swinging a bat before returning to pitch five postseason innings.
"If he has surgery, no. If he doesn't, yes," general manager Jeff Luhnow told reporters when asked whether McCullers would pitch in 2019. "Any time you're talking about an elbow injury, (surgery) is one path to resolving it."
McCullers went 10-6 with a 3.
