Did Bruce Bochy throw away the Giants' last legitimate chance tostay in the N.L. West race Sunday? Without question, it'll be a major topic of debate in the wakeof a killer 4-1 loss to the Arizona Diamondbacks, because there'snot much left to do now but gnash on what might have been. By losing two of three games to the team they came into theweekend chasing, the Giants are now seven games out with22 to play. That computes to kaput after yet another wimpy day bythe San Francisco offense three hits.
