CHICAGO -- For 15-plus seasons, the Rockies had one absolute mathematic equation -- RBIs equal wins.

Now it appears they're practicing new math.

Wednesday night's 1-0 victory over the Giants marked the first time since the Rockies began play in 1993 that they won a game without an RBI. Then they repeated the feat in Saturday night's 2-0 victory over the White Sox at U.S. Cellular Field.

However, the possibility exists that Colorado could go back to zero wins without an RBI. The Rockies have requested that baseball's statistician, the Elias Sports Bureau, review Wednesday's plays, and the club is likely to request a review of a call on Saturday.

On Wednesday, the Rockies scored the winning run in the ninth inning when Garrett Atkins scored on Yorvit Torrealba's bases-loaded fly ball. The play was ruled an error because Giants catcher Bengie Molina couldn't hold onto Fred Lewis' throw from left. Home-plate umpire Fieldin Culbreth made an emphatic out call before having to reverse himself.

Rockies club official Jay Alves confirmed that the club has sent a DVD of the play to Elias and asked them to reconsider changing the call to a sacrifice fly. The play was extremely close, with a high degree of difficulty -- Molina was trying to catch a throw in front of the plate, then dive and make a sweep tag. Also, Atkins said after the game that he felt his foot reached the plate before he was touched.

On Saturday, the go-ahead run came on Willy Taveras' hard grounder that bounced off White Sox first baseman Paul Konerko for what was ruled an error.

"Konerko told me he never saw the ball, so I don't think that was an error," said Taveras, who said he has asked the team to try to have the call changed.
