Weird that Cincy didn't keep him. He didn't get into trouble or something did he? Nah, the deal they made for him was one that made sense. They had a logjam in the OF and a need for pitching.
It'd be like Batman versus Captain America from the JLA/Avengers crossover a few years back. They'd start the fight, but after a few awesome moves, both would realize they were good guys and they would join forces.
