Kyle Blanks homer boosts San Diego Padres over Arizona Diamondbacks SAN DIEGO, June 16 (UPI) -- Kyle Blanks pounded a tie-breaking three-run homer in the eighth inning Sunday, boosting the San Diego Padres to a 4-1 win and series sweep of Arizona. With the score tied 1-1 in the eighth, Everth Cabrera singled with one out off David Hernandez (2-4) and after Alexi Amarista flied out, Chase Headley drew a walk. That brought up Blanks, who blasted a pitch into the second-deck balcony of the Western Metal Supply Co. building, providing the key runs as the Padres reeled off sixth straight victory overall and moved above .500 (35-34). Will Venable also homered for the Padres. Clayton Richard (2-5) registered the victory with eight innings of one-run ball. The left-hander didn't issue a walk and struck out one. Huston Street pitched a scoreless ninth for his 13th save. Diamondbacks starting pitcher Ian Kennedy, playing while appealing a 10-game suspension for his part in a brawl against the Los Angeles Dodgers last week, drove in Arizona's only run. The D-backs saw their lead in the National League West shrink to a half game over Colorado.
