With the San Francisco Giants fresh off a very successful road trip against the NL East, they now return home to the comfy confines of AT&T Park with the NL West back on their mind.

The San Diego Padres are in town for a three-game set, looking to spoil the Giants first place party. With just a 1.5 game lead over the rival Dodgers, the 41-52 Padres have been red hot since the All-Star break, losing just three of their 10 contests so far this second half. San Francisco has been just as good, losing just two of their contests since the break, setting up a showdown of streaking clubs at McCovey Cove.
