The enormous scoreboard at Coors Field went on the fritz for a couple of minutes in the first inning Tuesday night. That was the first omen that the Rockies were going to lose their ninth consecutive game to the Giants. The second was right-hander Dinelson Lamet’s maddening lack of pitch command. And so it goes. The final: San Francisco 10, Colorado 4 in front of an announced crowd of 29,190, many of them cheering for the visitors.
