The San Francisco Giants continue to enjoy the comforts of home. They'll look to extend their season-high home winning streak to eight games Wednesday night against the lowly Arizona Diamondbacks. Yusmeiro Petit allowed four hits and struck out nine while tossing the second complete game of his career, and rookie Joe Panik had five hits during Tuesday's 5-1 win over Arizona (59-85). Angel Pagan added four hits and Buster Posey had two RBIs for the NL wild-card-leading Giants (79-65), who trail the first-place Los Angeles Dodgers by 2 1/2 games in the West after winning for the 10th time in 13 contests.
