PHOENIX (AP) -- Ian Kennedy struck out nine in eight dominant innings and Arizona hit three late-inning homers to turn the Diamondbacks' home opener into a 13-2 rout of the Cincinnati Reds on Friday night.

Justin Upton homered, drove in two runs and scored three times in the Diamondbacks' highest-scoring home opener since the franchise was born in 1998. Kelly Johnson had a three-run home run and Chris Young a solo shot for Arizona. All three home runs came off reliever Matt Maloney.

Xavier Nady doubled in two runs off lefty Travis Wood (1-1). Arizona's Miguel Montero was 3 for 3, two of them doubles, to boost his batting average to .545 (12 for 22).

Kennedy (1-0), who had no decision as the opening-day starter in Arizona's 7-6 win at Colorado a week earlier, allowed six hits and walked one.
