San Francisco Giants’ righty Matt Cain held the Washington Nationals hitless though five, and the Giants’ pen allowed just one earned run in four innings in what ended up a 3-1 win. Gio Gonzalez was not particularly sharp, but the two runs that scored when he was on the mound were the result of errors. Washington settled for a split of the four-game set in AT&T Park, and they head off to Arizona for a three-game set with the Arizona Diamondbacks with a 61-44 record on the year.
