CINCINNATI -- Rockies catcher Tony Wolters is seeing something from right-handed pitcher German Márquez in his past two starts, something he likes a lot.

“When I see that no-fear look,” Wolters said, “whatever fingers I put down, he’s going to get this guy out. No fear.” The result of Marquez’s aggressiveness, Wolters said, “is letting [opposing hitters] get themselves out.”

On Friday night, Marquez allowed only two runs and five hits through seven innings of the Rockies’ 12-2 win over the Reds at Great American Ball Park. He struck out seven and did not walk a batter.

In two starts since allowing 11 earned runs over 2 2/3 innings in a 19-2 loss to the Giants on July 15, Marquez has given up just four runs in 14 innings.

“I thought German pitched with aggressiveness,” said Rockies manager Bud Black. “He made pitches down with the breaking ball. [Wolters] did a great job with the pitch selection.”

Marquez got plenty of support from his offense on Friday, particularly from Daniel Murphy, who went 2-for-5 with a three-run home run, his 11th of the season. He tied a career high with six RBIs.

Murphy now is batting .349 in his career against the Reds. It was his 10th career game with five or more RBIs, his second against the Reds.

“I can’t put my finger on it, because I would try to replicate it against every other team in the league,” said Murphy, of his success against Cincinnati. “I have family that usually comes to Great American Ball Park. The more I realize I have more baseball behind me than in front of me, it means more.”

David Dahl added a two-run homer, his 14th of the season, as part of the Rockies’ 14-hit attack.

Reds right fielder Yasiel Puig didn’t even flinch as Murphy’s three-run home run sailed over his head into the stands to give the Rockies a 3-0 lead in the first inning.

Luis Castillo had allowed three earned runs or fewer in 17 of his 20 starts, but the Rockies tallied six runs off him on Friday, the most given up in a game by the right-hander this season.

“Luis has been throwing the ball really well,” said Murphy. “He's got the electric fastball and the changeup can be pretty devastating. I happened to get a heater in the middle of the plate 0-0, and put a pretty good move on it and we were off and running then.”

Marquez who has struggled with home runs this season, gave up a solo shot to Josh VanMeter to cut the Reds’ deficit to 3-2 in the second. It was the 22nd home run allowed by Marquez, and the fifth in his last three starts. But on Friday, he continued to attack the zone.

“Baseball players, when you have confidence, you’re a different player,” Wolters said. “He was really attacking guys.”

Marquez (10-5) retired 10 straight in one stretch and earned his second-straight victory.

“He didn’t really make mistakes,” said Reds manager David Bell. “When he throws strikes, and doesn’t make mistakes over the middle of the plate, with his stuff that he has, that’s when he has good nights and good games.”

Marquez was also picked up by his defense on Friday.

In the seventh, second baseman Ryan McMahon scooped up Jose Iglesias’ grounder to start an inning-ending 4-3 double play.

The inning before, right fielder Charlie Blackmon robbed Jesse Winker of an extra-base hit with a leaping grab near the top of the wall.

“I thought it was going out,” said Marquez, who raised both arms after Blackmon’s catch. “It was a really good feeling. My mindset was to just keep working in the game. My whole point is to help the team win.”

Murphy’s bases-clearing double highlighted a six-run ninth inning to put the score out of reach. It was his 1,500th career hit.

“I asked him if he had another 1,500 in him,” said Dahl, smiling. “He wasn’t sure about that.”
