Pablo Sandoval’s MRI exam showed that his left foot strain was no more severe, but the Giants’ All-Star third baseman is likely headed to the disabled list anyway. “To be honest, we need to get this to calm down,” Giants manager Bruce Bochy said following a 6-2 victory at Arizona on Sunday. “You get an injury like this and try to get through it, you can end up losing him for a longer period of time.” Sandoval also appeared resigned to his third consecutive season interrupted by the DL, saying he didn’t know what was next but trying to give it a couple days might not be the answer. “That’s what I tried,” said Sandoval, who missed three games last weekend in St. Louis but aggravated the injury in the first inning Saturday night and exited in the third. “I don’t know how it’s going to be now.” Giants head athletic trainer Dave Groeschner said other opinions would be sought on treatment options and special footwear. The strain is in the mid outer area of his foot, Groeschner said. Sandoval was in a walking boot as the Giants dressed for their flight to Pittsburgh, where they begin a three-game series on Tuesday. “We’ll get together on the flight and talk about it,” said Bochy, adding that Sandoval would be out at least a few days. Sandoval missed more than a month in 2011 with a fractured right hamate bone in his right hand, then sustained the same injury to his left hand last season. He also went on the DL with a hamstring strain last year.
