DENVER -- Jeff Francis had a career-high 10 strikeout in the Rockies' 3-1 victory in Game 1 of Tuesday's split doubleheader with the Dodgers at Coors Field.

The Rockies picked up a game on the Dodgers in the National League West standings and trail the division-leading Padres by 4 1/2 games with 12 remaining, including Tuesday's nightcap.

Cory Sullivan smacked two doubles and scored the Rockies' first two runs. Matt Holliday drove in his National League-leading 123rd run with a single in the fourth, and first baseman Todd Helton drove in a run with a single in the sixth.

Joe Koshansky had a pinch-hit RBI double in the seventh, his first big league hit.

The Dodgers made it a one-run game in the seventh on a pinch-hit homer from Olmedo Saenz, the lone run surrendered by Francis in his 6 2/3 innings.

Francis set his career record against his final batter when he struck out Juan Pierre. It was the most strikeouts by a Rockies pitcher in the last 661 games, dating back to Aug. 8, 2003 when Jason Jennings struck out 10 against the Giants at Coors Field in a 6-1 victory.

Francis (16-8) needs one victory to tie the club record for wins in a season with Kevin Ritz (1996) and Pedro Astacio (1999).
