Ramon Hernandez hit a tiebreaking leadoff home run in the 10th inning, Joey Votto and Scott Rolen added back-to-back shots as the Cincinnati Reds broke out of their offensive slump to beat the Oakland Athletics 6-4 Monday. Oakland's Kevin Kouzmanoff tied the game with a leadoff home run in the bottom of the ninth off Reds closer Francisco Cordero before the Reds turned on the power in the 10th off relievers Michael Wuertz and Cedrick Bowers. Cordero (3-3) got the win after his fifth blown save of the season. He gave up a pair of walks leading off the 10th before two more Cincinnati relievers were needed to close the game out. Diamondbacks 10, Yankees 4: At Phoenix, Justin Upton, Adam LaRoche and Mark Reynolds homered off struggling A.J. Burnett in the first inning as Arizona cruised past the New York Yankees. Upton, who added a three-run homer in the eighth, reached base five times, had four RBIs and scored four runs. Miguel Montero was 3 for 4 with a double and two RBIs as the Diamondbacks won at home for the 11th time in 16 games. They have lost 14 of 15 on the road. Burnett (6-6) gave up seven runs and nine hits in four innings with no strikeouts and two walks. Rodrigo Lopez (3-6) gave up three runs and eight hits in eight innings for his first victory since May 15. Nationals 2, Royals 1: At Washington, Mike Morse and Cristian Guzman hit solo home runs and Livan Hernandez pitched seven strong innings as Washington snapped a six-game losing streak in a victory over Kansas City. Hernandez (6-4) had his longest outing since May 9, giving up one run and eight hits to help the Nationals snap their longest losing streak since an eight-game skid last Aug. 28 to Sept. 5. Matt Capps struck out the side - all on called strikes - in the ninth for his major league-leading 21st save in 25 chances. Bruce Chen (3-2), making his fifth start for Kansas City since moving from the bullpen, allowed two runs and three hits in six innings.
