MIAMI (AP) _ Unbeaten rookie Livan Hernandez allowed three hits in eight innings for his fifth win Wednesday night, leading the Florida Marlins past the Cincinnati Reds 6-0.

Hernandez, 22, became the first Florida pitcher to start a season 5-0. Dennis Cook pitched the ninth and gave up a hit.

Moises Alou had a three-run homer and a run-scoring double, giving him three homers and seven RBIs in two nights.

The Marlins began the night 7 1/2 games behind NL East leader Atlanta. The teams start a four-game series in Miami on Thursday.

Hernandez, whose status was uncertain until the Marlins this week decided against trading for a veteran starter, had a season-high eight strikeouts and walked two in his longest major league appearance. The Cuban right-hander has a 1.57 ERA in the past 34 1-3 innings.

Pete Schourek (5-7), who has been the subject of trade speculation, allowed six hits and four runs in four innings. The left-hander is winless in three starts since coming off the disabled list.

The Marlins, who scored four runs with two outs in the first inning of Tuesday's victory over Cincinnati, this time got three runs in the first with two outs on Alou's 14th homer. It followed walks to Edgar Renteria and Gary Sheffield.

Alou made it 4-0 in the third. Bobby Bonilla singled with two out, stole second and came home on Alou's double.

Center fielder Devon White, who had been 0-for-12 since coming off the disabled list, had an RBI single in the eighth. He also received a standing ovation after making a leaping catch on the warning track in the fourth inning to rob Eddie Taubensee of extra bases.

Florida scored an unearned run in the seventh when Renteria singled and later came home from third on a wild throw by third baseman Willie Greene.
