As any manager who's suffer through wild run-scoring games at Coors Field can attest, it's not the hits and homers that kill you. It's the walks.

The Rockies won the home run battle 2-1 Friday, but they walked nine to the Marlins' two, helping the visitors to a 13-5 win to open the three-game set and nine-game road trip. Winners of four of five meetings against the Rockies, the Marlins also totaled 16 hits on their way to their ninth win in 13 games. The last of those hits was Marcell Ozuna's second career grand slam, part of a six-run ninth.

"For us, any time we start talking walks we're going to be more successful just becuase we have a lot of younger guys that are basically figuring it out in the big leagues," said Baker, who exited after the seventh inning due to a head cold. "When you see us talking a lot of walks, I like our chances. It just takes one guy to win to get a big hit. When you have those opportunities you're going to cash in at some point."

Ozuna, Jeff Baker and Giancarlo Stanton's three each had three hits and every Marlins' starting position player tallied at least one. Six guys, including starter Henderson Alvarez, accounted for at least one RBI. Ozuna's five RBI-game matched the career-high he set May 21 against the Phillies.

"It's nice to come out and swing the bats like we know we're capable of," manager Mike Redmond said. "Henderson did a good job. I wouldn't say he had his best stuff. He made some mistakes up in the zone, but that happens here."
