Once on the brink of elimination, the Chicago Cubs have clawed their way back to the edge of history.

Tuesday's game 6 victory over the Cleveland Indians has forced a decisive game 7 Wednesday night, and it will cost fans a pretty penny to be on hand as one franchise ends its championship drought. Excitement appears to be at a fever pitch, too, as prices for game 7 World Series tickets are quickly increasing in the wake of the Cubs' game 6 win.

On TicketIQ, an event ticket search engine that pools tickets and data from more than 90% of the secondary market, the average resale price for game 7 World Series tickets is $4,700. That marks a 20% jump from the $3,922 average price prior to the first pitch of game 6.

Game 7 is the most expensive World Series game 7 since 2010, when TicketIQ began tracking resale data.

Wednesday's game 7 surpasses the deciding games of both the 2011 and 2014 World Series, and by a considerable margin. The meeting in 2011 between the St. Louis Cardinals and Texas Rangers had a resale average of $948, while the 2014 match-up between the Kansas City Royals and San Francisco Giants averaged $1,578 per ticket.

With the average resale price climbing, don't expect to find tickets for much cheaper if looking just to get past the gates at Progressive Field on Wednesday. As it stands now the cheapest game 7 World Series tickets are listed from $1,454 each, up 7% from the $1,363 get-in price prior to game 6.

The Cubs are seeking their first World Series title since 1908 and will end the longest-running championship drought in professional sports should they win in Cleveland on Wednesday night.

The Indians have experienced their own hardship in the Fall Classic, last winning the series in 1948. They have reached the World Series twice since then, falling to the Atlanta Braves in 1995 and Florida Marlins in 1997.
