Sandoval sidelined

SAN FRANCISCO — The San Francisco Giants are suddenly without their best hitter. Pablo Sandoval has a broken hamate bone in his left hand that will require surgery, and the slugger is expected to miss four to six weeks. It is the same injury Sandoval had last year on the other hand. There was more bad news for the Giants on Thursday as they dropped a 3-2 decision to Florida, and the Marlins completed a three-game sweep of San Francisco for their seventh straight victory.
