Troy underwent surgery for a fractured foot last week, Theo Mackie of the Arizona Republic reports.
Troy showed up in the dugout at Chase Field on Tuesday wearing a walking boot on his left foot. The 21-year-old shortstop, who was selected with the 12th overall pick this summer, said he originally hurt the foot in March when he was hit by a pitch but played through the injury. Troy added that stitches are set to be removed in two weeks and expects a full offseason of training. He hit .394/.478/.699 this year at Stanford, then slashed .271/.374/.469 in 27 games between the Arizona Complex League and High-A Hillsboro.
