Walker Buehler is still hoping to return to the Los Angeles Dodgers for the final month of the season.

The right-hander threw a modified bullpen session at Dodger Stadium before Tuesday night's game. Buehler threw from the mound to a catcher in a standing position.

Buehler had his second Tommy John surgery on Aug. 23. His first was in 2015 shortly after being drafted in the first round by the Dodgers.

"The 8 1/2, 9 months has gone pretty quick. I feel like I'm over two-thirds of the way," Buehler said. "Sept. 1 is still the goal. I want to get up to a certain pitch count where me being here is not a hindrance."

With Tommy John surgery recovery time usually 12-18 months, manager Dave Roberts admitted Buehler's timeline is aggressive.

"That's embedded in Walker, the confidence. That's not surprising," Roberts said. "Today was a good day and we'll see how he progresses."
