Madison Bumgarner pitched himself into the San Francisco record book, took a share of the major league lead for wins and, most important to the soft-spoken southpaw, moved his team one step closer in an NL West race that could go down to the wire. Bumgarner struck out eight on the way to his 18th victory, and the Giants moved within one game of NL West-leading Los Angeles by beating the Dodgers 9-0 on Friday night. ''It's not hard to get up for the Dodgers series, especially the circumstances we're in,'' Bumgarner said. ''The offense did an unbelievable job and kept scoring runs.'' Pinch-hitter Travis Ishikawa splashed a three-run homer into McCovey Cove, and Brandon Crawford hit a two-run drive in the fifth to help Bumgarner win his fifth straight start.
