(The Sports Xchange) - Madison Bumgarner struck out 12 batters in just six innings on Thursday, pitching the Giants to a 9-1 victory over the Chicago Cubs and earning his 16th win of the season. Marlon Byrd hit a three-run homer in the third innings while second baseman Kelby Tomlinson hit his first major-league homer, an eighth-inning grand slam, for the Giants to give Bumgarner all the support he needed. San Francisco (68-59) remain 2-1/2 games behind the NL West leading Los Angeles Dodgers.
