DENVER -- Two surging teams will meet when the Colorado Rockies and Los Angeles Dodgers begin a three-game series Tuesday at Coors Field.

The Rockies are coming off a 5-2 road trip in which they played Baltimore and the New York Mets. Colorado has won nine of its past 11 games and is 12-5 in the second half. Entering Monday, the Rockies (52-53) are five games behind Miami for the second wild-card spot, with St. Louis, the Mets and Pittsburgh also trailing the Marlins but ahead of the Rockies.

"We're playing really well, and it's really exciting where we are at right now," second baseman DJ LeMahieu said. "We believe in ourselves, and you can't fake that belief. Everybody is doing their job and doing it very well. Everybody knows their role, and we are executing. It's been fun."

The three-game series with the Dodgers is the start of an eight-game homestand that will include visits by the Marlins (three games) and Texas Rangers (two). The Rockies are 25-24 at home, having moved above .500 for the first time since they were 4-3 on April 22 when they completed a four-game sweep of the Braves on July 24 to conclude a 5-2 homestand.

The Rockies' starting pitchers recorded 20 quality starts in July, the most in franchise history for a single month. In the past 11 games, the Colorado starters have gone 8-0 with a 2.09 ERA (69 innings, 16 earned runs.

Jon Gray, who is 7-4 with a season-low 3.94 ERA in 18 starts and will take the mound Tuesday, has been a rotation mainstay as of late. He has pitched seven innings in his past three starts, going 2-0 with an 0.86 ERA in those games. Gray, who leads the team with 19 quality starts, is 4-0 with a 4.22 ERA in eight starts this season at Coors Field. He hasn't lost since July 3 when he gave up three runs to the Dodgers in six innings at Los Angeles, and the Rockies fell 4-1.

Rockies left fielder David Dahl will make his Coors Field debut Tuesday after hitting .370 (10-for-27) in his first seven games in the majors with two homers, three RBIs and six runs scored.

Rockies shortstop Trevor Story hopes to play. He jammed his left thumb and left Saturday's game in the fourth inning and didn't play Sunday.

The Dodgers were active Monday before the non-waiver trade deadline. They acquired outfielder Josh Reddick and starting pitcher Rich Hill from Oakland, and obtained reliever Jesse Chavez from Toronto and pitcher Josh Fields from Houston. Hill is on the disabled list with a blister but could return as soon as this weekend.

"We were real motivated to keep the momentum going and help the team's recent surge continue," general manager Farhan Zaidi said. "We're in a pretty good position to make a run, and we wanted to go out and get the pieces to help."

The addition of Reddick as a potential right fielder puts into question Yasiel Puig's status with the team. Puig did not travel with the Dodgers to Colorado on Monday after he was told he would be traded or demoted, FOX Sports reported.

The Dodgers were eight games behind the Giants in the NL West when Clayton Kershaw last pitched for them on June 26. They have since gone 18-10, including five wins in their past seven games, and are just two games behind the Giants.

The Dodgers averaged 4.14 runs per game in the 77 games while Kershaw was active. But in the past 28 games without Kershaw, the Dodgers have averaged one more run per game. And while going 15-9 in July, the Dodgers led the National League with an average of 5.25 runs per game.

Brandon McCarthy, who will start for Los Angeles on Tuesday, is 2-1 with a 2.39 ERA in five starts since returning from Tommy John surgery April 30, 2015. The first of those starts was July 3 against the Rockies at Dodger Stadium, and McCarthy threw five scoreless innings. In his two career starts at Coors Field, McCarthy is 0-1 with a 7.50 ERA. McCarthy has made six career starts against Colorado, going 2-2 with a 4.63 ERA.

Dodgers first baseman Adrian Gonzalez is one home run away from 300 for his career. But he has hit only nine homers this season. Gonzalez, who last homered on July 24, has hit 19 homers in 360 plate appearances at Coors Field where he is hitting .311 with a .943 OPS.
