Atlanta Braves reliever Tyler Matzek underwent Tommy John surgery on Wednesday.

Matzek, 31, felt discomfort in his elbow toward the end of the regular season.

After seeing doctors early in the week, it was determined he needed the surgery.

"Hate it for him," Brian Snitker said. "He's struggled with things all year. I don't know, maybe this is the reason. And I think him going ahead and getting it done and starting the process, I think he feels really good about that."
