Even so, he will not be idle during the final month of the season, and he will continue to play catch, run and lift weights.
"I'm doing all of my normal stuff. I'm just not going to be pitching," Zimmermann said.
After undergoing Tommy John surgery in 2009, Zimmermann had a limit of 160 innings, which he exceeded by 1 1/3 frames. Until he was declared done, he was Washington's best starter, going 8-11 with a 3.18 ERA.
"I feel great, and I feel strong. I wish I could keep going," he said."I know there is a process where you don't want to pitch too much. If I pitch another 40 extra innings and something happens, you are looking back, thinking, 'Maybe we should have shut him down.' I think it's probably the right move, and then I'll come back during Spring Training and be able to throw 200-plus innings."
In 2012, Zimmermann and Stephen Strasburg -- who is expected to make his season debut on Tuesday against the Dodgers after missing most of the season because of his own Tommy John surgery -- are expected to be the 1-2 punch in Washington's rotation.
Zimmermann can't wait for that to happen.
"I'm excited to have him come up this year and be able to watch him," he said. "I've seen him pitch a couple of times. His stuff is electric. I'm sure he will be on the same pitch limit. It's going to be an exciting year next year, and I can't wait."
