MIAMI -- Xavier Paul's three-run double and Homer Bailey's strong pitching powered the Cincinnati Reds to an 6-2 victory over the Miami Marlins on Tuesday night at Marlins Park.
It was the fourth win in a row for the Reds (23-16), who improved to 7-10 on the road.
The Marlins, the worst team in the National League at 11-28, dropped their third straight game. Miami has lost six of its past seven.
Bailey (2-3) pitched a complete-game six-hitter. He struck out 10 and did not walk a batter in a 125-pitch effort. He did hit a batter.
Miami's Ricky Nolasco (2-5) allowed six runs in five innings. He only gave up two walks, but both of those bases on balls drove in runs during a brutal, five-run second inning.
Joey Votto had three hits for the Reds, while Zack Cozart, Brandon Phillips and Ryan Hanigan each collected two hits.
The offensive standouts for the Marlins were a pair of rookie middle infielders. Second baseman Derek Dietrich had two hits, including a run-scoring single. Shortstop Adeiny Hechavarria stroked his fourth triple of the season and scored Miami's second run on a brilliant slide to avoid a tag by Hanigan.
The Reds broke the game open with a five-run second. Hanigan singled, Shin-Soo Choo was hit by a pitch and Cozart singled to load the bases. Votto and Phillips drew walks to give the Reds a 3-1 lead.
Paul, who entered the game with just 10 RBIs, worked the count to 3-1 and sliced an opposite-field, three-run double to left that eluded Juan Pierre and one-hopped the fence. That gave the Reds a 6-1 lead.
Before the fireworks, the teams traded first-inning runs. Cozart hit a one-out double down the line in left and scored on Phillips' single in the hole, just past a diving Placido Polanco at third.
The Marlins' first-inning run was sparked by Pierre, who grounded a double down the first base line. He advanced to third on a groundout to second by Polanco and scored on Dietrich's opposite-field single to left.
