The Reds sent left-hander Aroldis Chapman to Double-A Carolina Tuesday to restart his rehab assignment. Chapman made three rehab appearances for Triple-A Louisville. The most recent was on May 29. He spent the last week working with pitching coach Bryan Price in Cincinnati. The decision to send him to Carolina was purely for convenience. The Mudcats are home. The Louisville club is on the road. "It doesn't matter as much the competition as it does just getting on the mound," manager Dusty Baker said. "His main competition is himself, not who he's pitching against." Chapman was not successful in two of his three Louisville outings. He was 0-1 with 13.50 ERA overall. He allowed nine hits and seven runs in 42/3 innings. He walked two and struck out eight. "He's been working hard," Baker said. "We anticipate this time he'll be back with us. He's a big part of our bullpen." If Chapman is successful, his stay could be short. "It will be at least two outings," Baker said.
