Cubs Fans Cautiously Optimistic About Team Clinching

CHICAGO (CBS) --  The Cubs may be in San Francisco, but around the friendly confines of Wrigley Field, fans like Joe Mayse are keeping the Cubbie spirit alive with a familiar beat.

"The fact they've come so far this year, I just started bussing this year, but I feel like I'm doing something good for the team I love," he says.

The bars along Clark Street weren't packed during Game 4 between the Cubs and Giants on Tuesday night, but those watching are hoping for a win.

"I don't want to take any chances, win win win ... it's rare that we make it this far," Cubs fan Moe Arman said. "Obviously it would be nice to win in Wrigley, but let's get it done tonight."

A Game 5 would be good for local businesses, but even ticket brokers like Tim Collins say being a Cubs fan comes first.

"It'll be great on a money basis to play game on Thrusday, but it'll be best to see us play the Dodgers next week," he says.

And while the outcome of Tuesday's game is still unclear, what's clear is that prices for tickets to a possible Game 5 at home are already on the rise.

"The market is definitely going to pick up," Collins says. "I'd say between $150  for standing only to $250 on up."
