The Giants will probably have to contend with rivals like the L.A. Dodgers and San Diego Padres if they intend to sell San Francisco Giants playoff tickets this fall. Keep in mind that if the Giants can find a way back to the postseason, AT&T Park will be overflowing with fanatic Bay Area baseball fans, who can't get over their team's '02 World Series defeat.
If you were to travel back in time, all the way back to 1888, you would have seen the New York Giants win their first Pennant. MLB tickets to see the Giants play in the postseason have been around ever since, and as recently as 2003.
The Giants have one of the most spirited fan bases in Major League Baseball, and any playoff home game will prove that immediately. If the Giants can keep healthy and the Dodgers don't spoil things, the Giants could wind up in another NLCS in the next few seasons.
