Carlos Rodon will take the ball for the Chicago White Sox on Wednesday against the Cincinnati Reds in what Tony La Russa called an "interesting" and "important" start.

Rodon is looking to shake off arm soreness before the playoffs. He threw a bullpen session on Sunday in Cleveland.

"He didn't really let it go to where [it was] anything game-like but he said he's good to try it on Wednesday," La Russa said. "So we're good to see it."

Rodon has been hampered by arm fatigue in the second half, spending time on the injured list, then taking extra days between starts.
