Gaudin threw the equivalent of two innings in a simulated game Monday, but the Giants' decision-makers determined that he needed to sharpen his pitching repertoire further.
Gaudin, recovering from carpal tunnel syndrome, excelled in both the bullpen and in the starting rotation before being sidelined. He made his first 18 appearances in relief, recording a 2.05 ERA. Gaudin then replaced right-hander Ryan Vogelsong in the rotation and posted a 5-1 record with a 3.53 ERA in 12 starts. But Gaudin's physical unraveling was apparent in his final outing before he was sidelined, when he yielded eight runs and 11 hits in four innings on Aug. 16 at Miami.
