DENVER -- The Miami Marlins began an important nine-game road trip Friday night by trouncing the Colorado Rockies 13-5

The victory nudged the Marlins back above .500 (64-63) and kept them four games behind in the wild-card scramble.

The Marlins, who blew the game open with a six-run ninth that included a grand slam by Marcell Ozuna, will also play at the Los Angeles Angels and Atlanta Braves on this trip.

Miami has won 23 of its past 39 road games, after going 0-7 and 4-16 to start the season on the road.

Marlins starter Henderson Alvarez (10-5) gave up four runs -- two-run homers by first baseman Justin Morneau in the third and left fielder Corey Dickerson in the fifth -- and 10 hits in six innings. But that was good enough for Alvarez to win his fourth consecutive start.

Rockies starter Franklin Morales (5-7) gave up six runs and failed to retire any of the four batters he faced in the fifth before being replaced.

Every Marlins position player had at least one hit in their balanced 16-hit attack. First baseman Jeff Baker, who began his career with the Rockies, center fielder Ozuna and right fielder Giancarlo Stanton each had three hits. Ozuna had five RBIs, and Stanton drove in three runs.

Stanton singled home two runs in the ninth on an 0-2 pitch from Boone Logan after Logan loaded the bases on two walks and a hit batter. Juan Nicasio relieved Logan and gave up a single to third baseman Casey McGehee that loaded the bases for Ozuna, who hit his second career grand slam, both coming this season, to make it 13-4.

Rockies third baseman Nolan Arenado went 4-for-4 with two doubles, raising his average eight points to .306. Second baseman DJ LeMahieu, who came into the game with four hits in his past 61 at-bats, went 3-for-4.

The Marlins boosted their lead to 7-4 in the seventh when Matt Belisle issued a two-out walk to speedy shortstop Adeiny Hechavarria, who scored standing-up when second baseman Donovan Soloano rifled an opposite-field double into the right-field corner.

Dickerson broke a string of 10 hitless at-bats with a two-run homer with two out in the fifth off Alvarez, trimming Miami's lead to 6-4. It was Dickerson's 18th homer and came after a single by Arenado, his third straight hit.

Morales left in the fifth after issuing a bases-loaded walk to McGehee. Reliever Brooks Brown walked catcher Jarrod Saltalamacchia to force in another run and give the Marlins a 6-2 lead.

Morneau's two-run homer with one out in the third cut Miami's lead to 4-2. It was Morneau's 14th homer of the season and his first in 130 at-bats since June 24. Scoring ahead of Morneau was right fielder Charlie Blackmon, who led off with a bunt single.

The Marlins built a 4-0 lead against Morales through three innings. He gave up three straight singles to start the second, the third a run-producing hit by Hechavarria, and Alvarez hit a sacrifice fly.
