It's every Giants fan's worst nightmare. TimLincecum in Yankee pinstripes. Matt Cain fitting on a Boston RedSox cap. The Giants' co-aces, so adored here inthe Bay Area, bolting for greener, more potent pastures where runsupport arrives by the bushel. Cain and Lincecum have endured systemically poor support overtheir Giants career. No major leaguepitcher has worked with fewer runs per start than Cain since hebroke into the league in 2006. And Lincecum? The Giants haven't scored a run in 10 ofhis 26 outings this season including a 1-0 loss at Atlanta lastThursday.
