CINCINNATI (AP) - Zack Cozart and Todd Frazier hit upper-deck homers off left-hander Francisco Liriano, and the Cincinnati Reds moved a season-high 15 games over .500 by beating the Pittsburgh Pirates 4-1 on Monday night.
The Reds hit four solo homers in all, extending their best start since 1995, the last time they won a playoff series.
Cozart connected in the fourth and Frazier in the sixth off Liriano (5-3), who hadn't allowed a homer in his seven previous starts. He opened the season on the disabled list, recovering from a broken right arm last December.
Joey Votto and Jay Bruce connected in the eighth off Bryan Morris.
Mike Leake (7-3) extended the best stretch of his 4-year career, giving up six hits - including Russell Martin's RBI double - in seven innings.
