The Giants assigned Lincecum to the back field at Scottsdale Stadium, which is not open to fans. Once the games start and adrenaline rushes in, the Giants might see a clearer picture of Lincecum’s progress after nearly 50 offseason throwing sessions with his dad, Chris, in Seattle. Whether the 30-year-old can stay consistent into the Cactus League and regular season is the $18 million question, which cannot be answered by a swing and a miss, here or there, in February. Buster Posey is a very underrated verbal assassin, as Susac was reminded when he returned to work after a harrowing two days. Susac had a tooth infection that spread to his sinuses, his fever rocketed to 103.5 degrees, he required two hospital trips and intravenous antibiotics, then underwent a partial root canal. After declaring himself fit as a fiddle when he came to camp, Angel Pagan missed his second consecutive day of on-field work because of a stiff neck, and he is not expected on the field Saturday either, raising the possibility he will not be ready for Tuesday’s Cactus League opener against the A’s.
