MIAMI -- Jay Bruce keeps rolling along. The Florida Marlins, meanwhile, are headed the other direction.
Bruce continued his sizzling start in the majors with three hits and three more RBI, Johnny Cueto pitched six innings to win his third straight start, and the Cincinnati Reds beat the slumping Marlins 11-3 on Friday night, handing Florida its eighth loss in 10 games.
Ken Griffey Jr. remained stuck on 599 career home runs, going 2-for-3. He hasn't gone deep in his last 13 at-bats dating to last Saturday, when he moved one away from becoming the sixth member of baseball's 600-homer club.
But the Reds didn't need much pop from Junior on Friday. They scored a total of eight runs in four games at Philadelphia earlier this week, then needed five innings to score that many in the opener of this four-game set with the Marlins.
"The hitting funk in Philadelphia had to do with who was pitching against us," Reds manager Dusty Baker said. "Tonight the young man over there had a little control problem and helped us out."
The "young man over there" -- Florida starter Andrew Miller -- wasn't the only Marlins pitcher to struggle. Miller (4-5) allowed four runs and six hits and lasted just 3 1/3 innings, and the bullpen wasn't any better.
"I just didn't do my job," Miller said.
Jorge Cantu hit his ninth and 10th homers and added a double for Florida, which has a team ERA of 6.90 in its last 10 games.
"It was a rough night for everybody," Marlins manager Fredi Gonzalez said. "Everybody that was wearing a Marlins uniform had a rough night."
Those in Reds uniforms fared far better.
Jerry Hairston had three hits, and he and Brandon Phillips each had two RBI for Cincinnati. Bruce -- the Reds' first-round pick three years ago -- went 3-for-4, and is now hitting .463 with 10 RBI in 11 games since being called up late last month.
"I just try to stay with a consistent approach," Bruce said. "I'm trying not to change anything. A lot of people have told me the game's just the same. It's just bigger stands, better uniforms, superstars, stuff like that."
One highlight for the beleaguered Marlins' staff: They managed to strike Adam Dunn out four times, the seventh time in his career that the Reds' slugger has whiffed at least that many times in a game.
Cincinnati got four runs with two out in the fifth, blowing the game open. Cueto (5-5) got his first major league hit and RBI on a single for a 5-2 lead, Hairston followed with a ground-rule double to drive home another run, and Bruce drove them both home with a two-run single to center field.
Cantu's second home run of the game cut it to 8-3 in the fifth, but the Reds teed off again in the seventh with three runs off Matt Lindstrom. Dunn had a bases-loaded walk, Joey Votto's groundout brought home another run, and Andy Phillips' second hit of the season allowed Griffey to score easily and push Cincinnati's edge to 11-3.
After that inning, Baker took Griffey out of the game, and that was the sign for most of the 16,084 paid ticketholders to start leaving, too.
Cueto allowed eight hits, struck out eight and yielded three runs. He worked out of a bases-loaded jam in the fifth, striking Matt Treanor out looking on a 3-2 pitch -- after Baker visited the mound -- to end the threat and preserve what was then a five-run lead.
"That was a turning point for him and us," Baker said.
Griffey has only four home runs in 98 plate appearances at Dolphin Stadium. Still, the right-field seats seemed to be more filled than usual, with people clamoring to catch Griffey's 600th. They were anxious, but Griffey isn't. "I don't think about it," he insisted. ... The Marlins and Reds, who were rained out in Cincinnati on May 15, will play the rescheduled game Sept. 22. ... Reds reliever Jeremy Affeldt's first pitch measured 188 mph on the scoreboard. His next one was listed at 50 mph. ... Marlins LF Josh Willingham (back) is scheduled to take batting practice Saturday. There's no timetable for his return to the lineup. ... Florida's Wes Helms played left field in the ninth inning, the 12th outfield appearance of his 10-year career.
