SAN FRANCISCO -- The Giants' list of September callups probably will be relatively short and unsurprising, given the club's status as postseason contenders and the trio of position players awaiting activation from the 15-day disabled list. With no need to experiment with personnel or rush top prospects, the Giants will resist any temptation to promote left-hander Madison Bumgarner or catcher Buster Posey, the stars of their Minor League system. Second baseman Freddy Sanchez (left shoulder), infielder Rich Aurilia (left ankle) and outfielder Andres Torres (left hamstring) will leave the DL on or shortly after Tuesday, when Major League rosters can be expanded to a maximum of 40 players. Sanchez will return to his everyday role while Aurilia and Torres will provide depth, minimizing the need for additional reinforcements.
Nevertheless, the Giants are expected to summon performers who have spent time in the Majors this season and could prove handy as pinch-hitters, pinch-runners or late-inning substitutes. "There'll be a few to come up and give suppport to help us finish strong," vice president of baseball operations Bobby Evans said. Leading candidates for promotion from Triple-A Fresno include first baseman-outfielder John Bowker (.342, 21 home runs, 83 RBIs, .449 on-base percentage, .600 slugging percentage entering Sunday), first baseman Jesus Guzman (.324, 15 homers, 68 RBIs, .382 on-base percentage, .567 slugging percentage) and infielder Kevin Frandsen (.297, 13 homers, 54 RBIs). Right-hander Waldis Joaquin, who made a single one-inning appearance on Aug. 4 in Houston during a brief stint with the Giants, might return for a longer look. Joaquin is 5-5 with a 2.26 ERA in 43 appearances at Double-A Connecticut and Fresno. An intriguing possibility who has been the subject of recent speculation is left-hander Dan Runzler, who's 5-1 with a 0.78 ERA in 46 appearances for both Class A affiliates, Connecticut and Fresno. Runzler, 24, was San Francisco's ninth-round selection in the 2007 First-Year Player Draft.
