Road weary and a bit homesick, the San Francisco Giants picked up a victory Sunday that could be the momentum needed to get a long stretch in the Bay Area off to a good start. Nick Hundley and Brandon Belt each hit two-run home runs and Chris Stratton pitched six solid innings to help the San Francisco Giants avoid a three-game sweep at Los Angeles with a 4-1 victory over the Dodgers on Sunday. It marked the end of the Giants' fourth three-city road trip over the first 2 1/2 months of the season, and the last hurdle the club needed to clear before a stretch where they play 20 of the next 26 games at AT&T Park.
