CINCINNATI (AP) -- Ryan Roberts made the starting lineup because of an injury and hit two of Arizona's four homers off Sam LeCure on Tuesday night, leading the Diamondbacks to a 5-4 victory over the slumping Cincinnati Reds.

Roberts filled in for third baseman Melvin Mora and had the second multihomer game of his career, a solo homer and two-run shot off LeCure (0-1). Kelly Johnson and Chris Young also connected.

Armando Galarraga (3-0) went six innings and matched the best start of his career. J.J. Putz pitched the ninth for his fourth save in four chances.

The Reds have dropped five of six, leaving them only a game over .500 (9-8) for the first time since they won on opening day.
