The San Francisco Giants slow start has been compounded since arriving in Denver early on Thursday. No, the Giants did not have a game that day, but they still managed to lose when Madison Bumgarner was injured in a dirt bike accident. The San Francisco ace will be forced to miss at least six weeks, and perhaps longer, with a separated left shoulder and bruised ribs. In fact, the Rockies were determined to continue inflicting damage, defeating San Francisco 6-5.
