Home runs by Andrew McCutchen and Mac Williamson highlighted a six-run fifth inning and helped lift the San Francisco Giants to an 8-1 win over the Los Angeles Angels Friday night at Angel Stadium. Nick Hundley also homered for the Giants, who scored more on Friday than they did in their previous four games combined (five runs). San Francisco starting pitcher Jeff Samardzija (1-0), coming off the disabled list (strained pectoral muscle) to make his first start of the season, was not particularly sharp but managed to work his way through five scoreless innings to earn the victory.
