Tony Wolters had three hits and delivered a game-winning sacrifice fly in the bottom of the ninth inning, and the Colorado Rockies rallied to beat the Baltimore Orioles 8-7 in Denver on Sunday.

Nolan Arenado homered and starting pitcher German Marquez tripled and drove in three runs for Colorado.

Jonathan Villar and Trey Mancini had two hits each for Baltimore, which hasn't won two in a row since early May. The Orioles have lost 15 of their past 18 games.

Baltimore was on the cusp of a second straight win when it took a 7-6 lead on Mancini's two-run triple off of Scott Oberg (3-0) in the eighth. But the Rockies loaded the bases with one out in the ninth and Ian Desmond's full-count walk tied it.

Wolters followed with a fly to left to drive in the winning run as Colorado won for the fourth time in its last six games.

Paul Fry (0-2) got the loss for Baltimore.

The game was tied 1-1 when the Rockies rallied off starter David Hess in the sixth. David Dahl led off with a walk and Arenado hit Hess' first-pitch fastball into the seats in left to give Colorado a 3-1 lead.

Desmond and Wolters had two-out singles before Marquez tripled off the wall in right-center field to make it 5-1 and chase Hess. Hess gave up five runs (four earned) on nine hits and one walk with six strikeouts in 5 2/3 innings.

The Orioles came back in the seventh. With one out Austin Wynns, Stevie Wilkerson, and Villar singled to make it 5-2. Mancini singled on the next at-bat to load the bases and chase Marquez, who gave up four runs on seven hits with a walk and four strikeouts in 6 1/3 innings. Dwight Smith Jr. hit a sacrifice fly and Renato Nunez followed with an RBI single to cut the deficit to 5-4.

An error by first baseman Mancini in the bottom of the inning allowed Dahl to score and give Colorado a 6-4 lead.

In the second inning, Hanser Alberto reached on a one-out walk and moved to third on a single by Keon Broxton. Wynns put down a bunt to Marquez and Alberto scored to put the Orioles ahead 1-0.

In the fifth, Brendan Rodgers led off with a single and an error on Wolters' infield single put runners on second and third with one out. Marquez bunted to Hess but Rodgers beat the throw home to tie the game.
