SAN FRANCISCO — Matt Cain has tried not to think about his tenuous hold on a rotation spot, and the organization would never come out publicly and say a pitcher is out there on a start-by-start basis. But there was no hiding the fact that the Giants have for weeks pinpointed next week as a potentially big one for the back of the rotation.
Cain’s spot could have been skipped, and had he gotten off to an awful start this month, that could have been the first of many changes. Instead, Cain will start Tuesday in Kansas City, manager Bruce Bochy said.
