ANAHEIM –- Jesse Hahn will miss his next scheduled start Thursday, with long reliever Jesse Chavez stepping in to take the ball against the Angels, manager Bob Melvin announced.
Hahn is dealing with a blister on the middle finger of his throwing hand that forced him from Saturday’s start at Kansas City in the sixth inning. He played catch Monday, and though he said the blister is getting better, the A’s don’t want the issue to linger.
“It looked better today than I expected it to,” Melvin said. “We’re just going to make sure this goes away one time around.”
As for when Hahn returns to the rotation, Melvin mentioned that the A’s have some flexibility because of a day off next Monday.
Chavez has experience filling in for spot-start duty, and he’s proven to be the most versatile pitcher on the A’s staff. He came in for Hahn on Saturday and blanked the Royals over the final 3 2/3 innings, striking out six.
In other rotation news, right-hander Jarrod Parker will begin a minor league rehabilitation assignment with Single-A Stockton when he pitches Thursday at Visalia. Parker underwent his second reconstructive elbow surgery in March 2014, and to this point his recovery has gone extremely well. Reports from his outings at extended spring training have been glowing, with Parker topping out at 94 miles per hour with his fastball and mixing in his curve and changeup.
Rehab assignments can last a maximum of 30 days for a pitcher, meaning the A’s can keep Parker in the minors through May 22. After that, they’ll need to add him to the active roster or option him to the minors.
And in one final note, don’t be surprised to see interim closer Tyler Clippard called upon in the eighth inning. Melvin said he’s considering using Clippard for four-out saves if need be. The first-year Athletic has yet to even get his first save opportunity. Part of that is because the A’s have posted some lopsided victories, but Oakland’s bullpen also has had some trouble sustaining a lead to carry into the ninth.
“We’re trying to search for the right recipe,” Melvin said of his bullpen. “That’s my job, and it hasn’t worked out so far. Overall, we’ve had some good games and had some bad games. The bad games we’ve had have affected whether we’ve won or lost the game. We’re still trying to figure out what the best mix i
