Burnett had a good minor league progression, and progress happened to stop when he was brought up to the majors in 2010, skipping AAA. And he did all right up through the middle of June, posting a 2.70 ERA. After that, he fell apart, got sent to AAA, was brought back up, and totaled a 11.30 major league ERA the rest of the way. Does anyone remember if something "happened" to him, like a nagging injury? Or did the league suddenly find out he sucked?
