The Dodgers are 17-1-2 in their last 20 series thanks in large part to Ricky Nolasco continuing his 1987 Doyle Alexander impression.

Ricky Nolasco gave the Dodgers another solid start on the mound while Carl Crawford and Nick Punto gave the lineup a good start. But it was a big assist by Rockies infielder turned outfielder Charlie Culberson that allowed the Dodgers to finish their 7-4 win on Tuesday night at Coors Field.

Up 4-3 with the bases loaded and two outs in the ninth inning Mark Ellis drove a ball to deep left center field. Culberson ran the ball down but failed to catch it allowing three insurance runs to score.

The Dodgers built a 4-0 lead thanks to Crawford and Punto at the top of the order. Each had hits in their first three at-bats including a two-run single by Crawford in the second inning. Crawford has four straight multi-hit games hitting .556 (10-for-18) during that span.

Nick Punto stared at shortstop in place of a resting Hanley Ramirez and finished 4-for-5 on the night his first four-hit game since Sept. 27 2011 when he was with the Cardinals. Since Aug. 1 Punto is hitting .340/.433/.500 in 20 games.

Nolasco didn't allow a run in his first four innings extending his scoreless streak to a career-high 20 innings. His previous best was 15 consecutive scoreless innings done twice with the Marlins the last time in 2011.

Single runs allowed to the Rockies in the fifth and sixth innings ended his night but not before Nolasco had his fifth straight quality start. Nolasco won his sixth straight decision and improved to 7-1 with a 2.27 ERA in 11 starts as a Dodger. The most runs he has allowed in any start since joining the team is three.
