Todd Helton started his final homestand with a key single in the eighth inning and the Colorado Rockies beat the St. Louis Cardinals 6-2 on Monday night.
Charlie Blackmon had three hits and drove in three runs for the Rockies, who prevented the Cardinals from taking over sole possession of first place in the NL Central.
They remained tied with the Pittsburgh Pirates, who lost 2-0 to San Diego.
Matt Carpenter and Matt Adams had two hits each for the Cardinals.
Helton was playing in front of Colorado fans for the first time since he announced his plans to retire at the end of the season, his 17th.
He received a standing ovation when he came to the plate in the first, and Cardinals starter Lance Lynn stood behind the mound and waited as the crowd saluted Helton.
