SAN FRANCISCO — The Giants gave up 13 runs in the fifth inning Thursday night.
It was the first time they allowed at least a dozen runs in an inning since … well, since last week.
For the second time in seven games the Giants filled up a scorebook the wrong way. Matt Cain and Vin Mazzaro combined to give up 10 hits, walk one and hit one in a 37-minute top of the fifth, and there’s no coming back from that. The Giants lost to the Rockies 17-7 on a night when the questions about the back end of the rotation continued to get louder.
