May (back) is scheduled to throw a bullpen session Sunday, Mike Bernardino of PioneerPress reports.
May was placed on the 15-day DL on June 10 with back soreness but he's now set to begin throwing off a mound again. If all goes well during his bullpen stint, a rehab assignment could be on tap late next week. The 26-year-old righty will look to turn things around in his 2016 season once he makes his return in the next several weeks as he's coughed up 14 earned runs over his last 7.2 major league innings (16.43 ERA).
