Rodriguez (elbow) threw 30-pitch bullpen sessions at Oracle Park on Thursday and Sunday, MLB.com reports.
After being placed on the 15-day injured list Aug. 15 with a right elbow flexor strain, Rodriguez was shut down for two weeks before he was cleared to begin a throwing program Sept. 3. He looks to be building up his pitch count through side sessions and should soon be ready to face hitters before likely heading out on a brief minor-league rehab assignment. Rodriguez could make it back from the IL during the final week of the regular season.
