Arroyo has been bothered by the condition for years, but it improved this season when he gave up playing the guitar. For now, he feels he can do without going under the knife.
"I'm going to wait it out for another year," he was quoted by the AP. "I feel too good throwing the ball now."
In 2009, Arroyo led the Reds in wins (15) and the starters in ERA (3.84) while pitching a team-high 220 1/3 innings. After his wrist flared up during Spring Training, he gave up playing the guitar during the season and his hand improved.
Arroyo plans on playing the guitar again in the offseason, then give it up during the '10 campaign, the AP added.
The 32-year-old, who made $9.5 million this season, has one guaranteed year left at $11 million next season, then could become a free agent, which reportedly factored into his decision to put off risky surgery. The contract also includes a club option of $11 million for '11, with a $2 million buyout.
