Joel Hanrahan (hamstring) will make another rehab appearance with Triple-A Pawtucket on Sunday, then hopes to return to the Red Sox bullpen for Tuesday's series opener against the Blue Jays. Hanrahan has adjusted his mechanics during his rehab stint, and reiterated Saturday that he no longer had any hamstring problems. It's unclear how Red Sox skipper John Farrell will handle the closer's role upon Hanrahan's return, but with Andrew Bailey pitching well in the role, he could have a tough decision on his hands.
