PITTSBURGH — Ricky Nolasco used his arm and bat to help the Florida Marlins have fun again.

Nolasco pitched six shutout innings for the second consecutive start and added two hits and two RBI as the Marlins snapped a four-game losing streak with a 6-0 win over the Pittsburgh Pirates on Tuesday night.

"Our intensity and our competitiveness was at a different level tonight, and I think our level of having fun was at a higher level, too," said second baseman Dan Uggla, who was vocal during a closed-door, players-only meeting after a 7-1 loss to Pittsburgh on Monday.

"I think everybody showed up with a different attitude today. Everyone was smiling all day. I think we came out with a much higher level of intensity," he added.

Nolasco (14-8) extended his road winning streak to seven games and won for the fifth time in six starts overall. He allowed five hits — all singles — and a walk with nine strikeouts.

Nolasco, 10-2 on the road this season, also snapped Florida's streak of 34 hitless at-bats with runners in scoring position with a fifth-inning RBI single.

That scored Wes Helms to break a scoreless tie and was the first of four consecutive singles, the last of which was Gaby Sanchez's liner to right that scored Nolasco and Hanley Ramirez. Uggla followed with a sacrifice fly.

Jose Tabata and Pedro Alvarez each had two hits for Pittsburgh, which has lost eight of nine and was shut out for the 13th time this season.

The second Pittsburgh batter of the game, Tabata, singled. But he was caught stealing, and Nolasco retired the next 15 Pirates before pinch-hitter Andy LaRoche's two-out single in the sixth.

Andrew McCutchen then walked and Tabata hit an infield single to load the bases. But Nolasco struck out No. 3 hitter Neil Walker swinging.

"I threw a real good splitter there on a 2-2 count, and he chased it and I got the strikeout," Nolasco said. "That obviously was probably the biggest pitch of the game."

The first two batters of the next inning singled, but Jose Veras induced Ryan Doumit to fly out on his first pitch and got Chris Snyder to ground into a double play.

Pirates starter Zach Duke (5-12) had allowed only three hits through the first four innings until the four-run fifth.

"That's hurt him this year, getting into those innings he can't get out of," Pirates manager John Russell said. "He was going along pretty well until that inning."

Despite spending nearly a month on the disabled list, Duke moved into a tie for the second-most losses in the majors. He allowed five runs on nine hits and two walks in falling to 0-4 lifetime against the Marlins.

"I started leaving the ball up, and when you do that, obviously, you pay for it," Duke said. "I'm just going to try to erase that start from my memory."

Notes: The Pirates have scored one or zero runs in 24 of their 119 games this season, or more than 20 percent of the time. ... The Marlins had lost their previous five games at PNC Park.
