Manager Robin Ventura said Rodon (wrist) will likely start Sunday against the Twins, the Chicago Tribune reports.
The fact that the White Sox optioned Anthony Ranaudo to Triple-A on Thursday seems to foreshadow Rodon's activation this weekend. He should return to the majors for a favorable matchup - a Twins' lineup that may be further thinned by trades ahead of the July 31 deadline.
Hanigan (illness) took part in full baseball activities Thursday and is expected to start Friday, Tim Britton of the Providence Journal reports.
Hanigan has missed the last three games due to flu-like symptoms.
Buchholz's last two appearances have impressed manager John Farrell, who said the right-hander will used situationally rather than exclusively in a mop-up role, Jason Mastrodonato of the Boston Herald reports. "The way he's thrown the ball of late, yeah," Farrell said. "He's going to throw strikes, he's got a full complement of pitches he uses, even in shorter stints, he's done a good job of that. If the situation arises, depending who is available, he will be called upon... I think he's thrown the ball very good."
Buchholz has pitched better in his last two outings, allowing one run on two hits in three innings, but he's not that far removed from some poor outings. At one point he went 19 days between appearances, so it's hard to see Farrell consistently using him in high-leverage situations. There's a chance that the right-hander becomes a classic "change of scenery" guy as another team could find some interest in the former starter.
Young, who is currently traveling with the Red Sox on the current 11-game road trip, will get back to Boston on Aug. 8. Until Young is activated off the disabled list, Brock Holt will be the primary left fielder for Boston.
O'Sullivan allowed six runs on six hits in three innings during a rehab start at Triple-A Pawtucket. He struck out four and didn't walk a batter.
O'Sullivan lasted just 53 pitches before getting yanked. The right-hander, who had a few starts in Boston when the Red Sox had some problems at the back end of the rotation, is expected to be assigned to Pawtucket when he's ready to come off the disabled list.
