The Rockies’ power shortage is one of their most glaring weaknesses. Their 144 home runs rank 28th in the majors, and the 45 dingers hit by their outfielders also rank 28th. In order for their fortunes to change, that must change. Although Colorado’s five-game winning streak — its best run of the season — came to a halt with an 11-10 loss to the Giants on Sunday afternoon at Coors Field, rookie outfielders Hunter Goodman and Brenton Doyle supplied some juice and a flicker of hope. In the Rockies’ five-run sixth inning, Goodman, who started in right field, hit the first home run of his career, a two-run blast to left field that traveled 437 feet.
