Tonight, at AT&T park the Giants will have the first of three chances to clinch the National League West Division Championship.
It would be their first division championship in seven years. The team's magic number stands at one following Thursday's win over the Diamondbacks and a loss by the Padres.
The Giants need to beat San Diego just once this weekend to clinch.
Tonight, the Giants send Matt Cain to the mound -- making the start on his 26th birthday.
The game is sold out. On Craigslist, upper deck seats are going for four times face value, bleacher seats are going for 20 times face value.
