Arizona Diamondbacks catcher Robby Hammock, right, waves while stretching as first baseman Paul Goldschmidt, left, looks on before their baseball game against the San Francisco Giants in San Francisco, Friday, Sept. 2, 2011. The Diamondbacks selected Hammock's contract from Triple-A Reno on Friday, another addition by general manager Kevin Towers for the pennant race after first-place Arizona added four players Thursday when rosters expanded. Hammock last played for the club in 2008. (AP Photo/Eric Risberg) less
