OAKLAND -- While left-hander Brett Anderson continues to progress through rehab from Tommy John surgery, A's right-hander Jarrod Parker is much further along, having established himself in the Oakland rotation this season. But even though Parker is two seasons removed from his own Tommy John operation, the organization is still being careful to limit the wear on the rookie.
To that end, the A's switched spots in the rotation between Parker and left-hander Travis Blackley. Parker will now start on Friday against San Francisco, giving him a full seven days of rest since his last outing, and Blackley will start Thursday's series finale against the Dodgers.
Oakland manager Bob Melvin said it was important to look at controlling Parker's innings. Other factors played into the decision as well, like separating Parker and left-hander Tommy Milone from Blackley, who was pitching in the bullpen earlier this season and hasn't gone as deep into games as the other two.
"[Parker] just pitched in Arizona and Colorado, two difficult places to pitch, expended a lot of energy," Melvin said. "We are very careful with him. Maybe breaks up some of the innings-eaters as opposed to some of the guys that might not potentially go as far. We took a look at all those things and we flip-flopped those two."
Parker has gone 3-3 with a 2.82 ERA in 10 starts and hasn't thrown more than 112 pitches in a start. Melvin earlier had a difficult decision to make regarding the righty when Parker had a no-hitter going and high pitch count on June 4 againat Texas, but the rookie eventually gave up a hit in the eighth inning.
