PITTSBURGH (AP) Pirates right-hander A.J. Burnett is hopeful of returning to the rotation by mid-September following a 71-pitch bullpen session on Sunday.
The 38-year-old Burnett has been on the disabled list since July 31 with a strained flexor tendon in his right elbow.
''It was good, better than expected,'' Burnett said of the bullpen session. ''The pain is gone and I feel good.''
Burnett is scheduled to throw a simulated game Friday and then hopes to make a start during a four-game home series against the Chicago Cubs from Sept. 15-17.
Burnett is 8-5 with a 3.06 ERA in 21 starts. But he is 1-2 with a 10.13 ERA in three starts since the All-Star break.
The Pirates also shuffled their rotation Sunday, announcing that Gerrit Cole will start Tuesday night at Milwaukee instead of Wednesday night. Left-hander Jeff Locke will pitch Wednesday instead of Tuesday.
The move put Cole in line to pitch next Sunday night against the Cardinals in the finale of a pivotal three-game series at the NL Central leaders.
