Prado Power!

Martin Prado went 4 for 4, drove in four runs and scored twice as the Arizona Diamondbacks beat the Tampa Bay Rays 9-8 tonight to keep pace with the LA Dodgers in the NL West.

Prado's big blow came in the eighth inning when his two-run single to right field turned an 8-7 deficit into a 9-8 lead. The slim lead held up as Brad Ziegler pitched a scoreless ninth to pick up the save. J.J. Putz (3-1) picked up the win by pitching a scoreless eighth inning.

Prado singled twice, doubled and hit a two-run home run. Adam Eaton, Eric Chavez and Aaron Hill collected two hits apiece, while Paul Goldschmidt singled in a run -- his 90th run batted in this season.

Arizona (58-55) set a club record by turning six double plays tonight -- including a 6-4-3 double play to end the game.

It was Arizona's 23rd win of the year in one-run games and the victory tonight capped a two-game sweep of the visiting Rays.

The two-game sweep of the Rays allows the Diamondbacks to pick up one full game on the Dodgers (63-50) and are now five games back of LA in the NL West Division race.

Arizona begins a three-game series on Friday at Chase Field against the New York Mets.
