The Arizona right-hander, who walked nine in his start Saturday against the Rays, blamed his control problems on mechanical issues, and he felt he corrected them during Tuesday's session.
"I was dotting the corner of the plate and I was like, 'I didn't feel that Saturday,'" Kennedy said.
Kennedy has taken some good-natured ribbing from his teammates about getting an extra few days between starts. The team is trying to give him some additional rest since he is on pace to shatter his career high in innings pitched.
"They asked if I was on paid leave," Kennedy said. "Or on vacation."
Kennedy also said that his actual career high for innings in a year was 170 set in 2007. That total would include his winter ball stint.
