Patrick Wisdom homered again, Marcus Stroman pitched six scoreless innings for his first win in more than two months and the Chicago Cubs beat the struggling San Francisco Giants 4-2 on Friday night. Wisdom connected for the second consecutive day and also doubled in the ninth as the Cubs scored three times to take a 4-0 lead on the way to their seventh victory in eight games. Wilmer Flores hit a two-run homer off closer David Robertson in the bottom of the ninth before the right-hander struck out Thairo Estrada to end it.
