You could regard the Giants' season-ending, 15-0 defeat that the Dodgers handed them Sunday as an embarrassment. Or you can consider it a strangely fitting farewell for Giants right fielder Hunter Pence, who might have played his final Major League game Sunday. Pence, whose contract ended with this season, was all about the effort -- unquenchable, ceaseless, joyful effort -- that he brought to each of the 772 games he played for San Francisco.
