Moehler, who doesn't have a contract for next year, has been dealing with a sore knee for much of the season. The 37-year-old was on the disabled list in April with a sprained right knee.
"I'm just going to have it cleaned out," Moehler said. "It's been bothering me since the beginning of the year. It's there. It's nothing major, but I just need to clean it up.
"If I had just a normal daily life, I probably wouldn't have the surgery, but for what I do I need to have it done. I need to have it cleaned up."
Moehler is 8-10 with a 5.01 ERA this year.]]>
