Jake Cave has been a sparkplug for the Rockies this season, running down flyballs in the outfield, taking extra bases and pumping up his teammates. Thursday night, Cave provided the fireworks. His solo homer to dead center in the sixth inning lifted Colorado to a 4-3 win over Milwaukee in front of an Independence Day crowd of 48,705 at Coors Field. Cave’s first homer of the season came on a 1-0 fastball by Brewers starter Tobias Myers.
