Within just a few minutes of Cuban pitcher Aroldis Chapman's arrival in the United States, Reds manager Dusty Baker had already overused and mangled the 21-year-old's arm beyond recognition, team sources reported Sunday. Baker, who has been accused of overtaxing young pitchers' arms in the past, reportedly greeted Chapman with a bucket of 250 baseballs and told him to 'hurl them' as fast as he could, later encouraging the fastballer to 'go nuts' with his pitching style. 'He didn't even let me stretch out first,' Chapman told reporters through an interpreter. 'And when I started to wince from the pain and soreness, he just gave me a thumbs up, winked, and told me to keep throwing.' At press time, Chapman had already been to the hospital for an oblique strain, a torn rotator cuff, and his second Tommy John surgery of the week.
