A.J. Burnett's first week with the Pittsburgh Pirates ended with a fractured right orbital bone. His first three rehab starts ended with losses, a gaudy 9.53 ERA and concerns the veteran right-hander couldn't become the ace his new team so desperately needs. Never mind. Pitching brilliantly after a shaky first inning, the former New York Yankee pitched three-hit ball for seven innings to lift the Pirates to a 2-0 victory over the St. Louis Cardinals on Saturday.
