"I don't know that answer," the 29-year-old Zimmermann said. "We'll see what this offseason brings. I enjoyed my time here. We'll see after the season."
If he departs, Zimmermann will be missed, according to bench coach Randy Knorr.
"I think he is going to be missed tremendously," Knorr said. "You take a consistent pitcher out of your rotation -- that gives you innings and shows up every five days to pitch -- it's hard to replace. You take that consistency out of your rotation, you have to find another pitcher."
