NEW YORK -- As expected, A's right-hander Jesse Hahn went on the disabled list Saturday, clearing roster space for Jharel Cotton, who started the second of a three-game series in New York.
Hahn, nursing a right triceps strain, will likely soon be joined by right-hander Kendall Graveman, who has been bothered by shoulder soreness. The A's have yet to make a move involving Graveman but could do so as soon as Sunday.
A's manager Bob Melvin is hopeful to have Hahn back after the minimum 10-day period (June 3), but the team will be cautious with both pitchers, who have dealt with similar injuries in the past.
"The MRI was clean," Melvin said of Hahn, "so it's just a matter of giving him some rest and making sure he's as close to 100 percent when he comes back. It's kind of been on and off with this for a few years, and when these type of things pop up, you don't want it to get more severe, so we'll give him some rest."
Hahn was removed from his latest start after just two innings and 48 pitches. It was his ninth appearance overall this season and eighth start. He pitched to a 1-4 record and 3.81 ERA in that span, allowing three earned runs or fewer in all but the last outing.
The A's have had at least five players on the DL all year.
A's first baseman Yonder Alonso, who was hit by a pitch in the right wrist Tuesday evening, remained out of the lineup Saturday, as expected, but was potentially available off the bench after joining the team for batting practice.
Barring any setbacks, the A's anticipate having Alonso back in their lineup for Sunday's series finale at Yankee Stadium.
