Haeger also took the loss in Rancho Cucamonga's 5-0 victory over the 66ers.
Haeger (0-4, 8.53) struck out 12 in his first big league start of the season but has been dismal since. This is his second trip on the disabled list: While recovering from a heel injury that put him on the DL for the first time on May 9, he suffered turf toe in his right big toe. He made one appearance after returning from his first DL stint, on June 5 against the Braves, but he allowed two runs in as many innings and the team felt he rushed himself back.
Haeger was sent back to the disabled list on June 7, a day before reliever George Sherrill returned from it. He is out of options and would have to clear waivers to be sent to the Minors.
