Alex Wood's fastball wasn't as sharp as usual, yet his stuff was still effective and the results were the same. Adrian Gonzalez hit his third home run of an injury-plagued season and Los Angeles beat the San Diego Padres 9-2 on Tuesday night to clinch home-field advantage throughout the National League playoffs. Yasmani Grandal and Corey Seager each had a three-run homer to back Wood (16-3) as the NL West champions improved to 101-57.
