Ryan Roberts did his best Kirk Gibson impersonation, pumping his fist in triumph as he rounded the bases in one of the most amazing moments of Arizona's improbable season, and the Diamondbacks' skipper didn't mind at all. "Some things rub off," Gibson said. "He deserved to do it." Roberts' grand slam capped a six-run 10th inning that gave the Diamondbacks the most stunning of their 48 come-from-behind victories this season, a 7-6 triumph over the Los Angeles Dodgers on Tuesday night.
