SAN DIEGO, June 7 (UPI) -- Matt Cain allowed three unearned runs in seven innings but the San Francisco Giants pounded San Diego with three home runs Thursday to beat the Padres 8-3.
Cain (7-2) allowed seven hits and struck out nine, and ran his winning streak to six straight starts for the Giants, who won for the ninth time in 11 games.
The Giants went up 4-0 in the third on a solo home run by Buster Posey, who had driven in a run in the first with a single. The Padres scored three times in the bottom of the third, aided by two San Francisco errors.
Angel Pagan hit a two-run shot in the seventh and Gregor Blanco had a solo home run in the eighth for the Giants.
Jason Marquis (0-1), making his first start for the Padres, went six innings, giving up four runs -- two earned -- on nine hits and striking out six.
