"Sure, Jason Giambi is the most recognizable name - and face - coming off the Colorado bench, but the Rockies had established their bench identity well before the former Yankees/Athletics slugger headed their way just over a month ago. "His presence has helped, but as far as coming in and helping the bench guys, we already had strong bench guys," said Colorado reserve outfielder Ryan Spilborghs."I think a lot of guys on this team have been doing this bench role for a bit so we have an understanding. But as far as making our bench better, he obviously makes our bench so much stronger."The National League division series begins this afternoon at Citizens Bank Park and those not scheduled to start for the Rockies against the Phillies - Giambi included - understand exactly how big of an impact their limited at-bats could have. Spilborghs, hitting .241 with 48 RBIs, is one of three Colorado reserves with more than 45 runs batted in; infielder Ian Stewart has 70 and outfielder Seth Smith has 55. Giambi, 38, signed with the Rockies on Aug. 23, two weeks after being released by the Oakland A's. He made his first plate appearance for Colorado on Sept. 1."
