Joe Beimel (elbow) will throw another bullpen session Tuesday before beginning a rehab assignment with High-A Bradenton. Beimel felt great during a bullpen session Saturday. "I'm pretty happy right now," he said. "No pain, the ball was coming out of my hand well. The pitches were crisp." The lefty will eventually move his rehab up to Double-A Altoona before rejoining the Pirates. He's probably a week or so away from returning.
