Brenton Doyle’s star keeps getting brighter. The Gold Glove center fielder delivered a bases-loaded, two-run double in the eighth inning to power the Rockies to a stirring 4-2 victory over Kansas City on Friday night at Coors Field. Doyle ripped John Schreiber’s 1-0 sinker into the right-field corner. Doyle finished the game 3 for 4 and has gone 10-for-15 (.667) with four doubles and three home runs over four games on the current homestand.
