As the 2010 season began, Aroldis Chapman was in AAA Louisville trying to work his way up into the rotation of the Cincinnati Reds. After a strong season by the rotation, the Reds converted him into a reliever and brought him up to the majors. He served as a reliable lefty out of the bullpen and helped the Reds make the postseason.
In 2011, he was still a member of the bullpen but had trouble controlling his fastball. After time on the DL and taking speed off of his fastball, he quickly returned to dominance.
After an offseason of moves by the Reds, Chapman’s role was unclear. Cincinnati fans were pleading for manager Dusty Baker to give Chapman a spot in the rotation. After an injury to Ryan Madson and the occasional struggle by Sean Marshall, Chapman finally got a chance to move into the closer role.
With his control problems figured out, where does Aroldis Chapman rank among the best relievers in baseball? (Stats as of Monday, 5/28)
