DENVER, Colo. -- Back in September, a Rockies season ticket holder was proud to show off his World Series tickets.

"It's pretty cool to see Rockies on a World Series ticket," said the fan.

It was pretty cool then, and it still is now. But, it's a sight on which many Rockies fans won't get to lay their eyes on.

"I hate it," said Theresa Ferrari.

Ferrari, like several other diehard Rockies fans, are scrambling to score a ticket. It's not an easy task, even though Ferrari was a partial season-ticket holder.

The Rockies just announced the only way to get the tickets is by purchasing them online. The policy has some fans crying foul.

"I think going down and standing in line gives you a shot. I think the thing that bothers me the most is opening it up to the Internet. It opens it up to the world," said Ferrari.

It means a person in London can get a ticket just as easy as a Colorado resident. That begs the question, how many resident Rockies will actually be in the stands?

"Somewhere between 18,000 and 17,000 for each game when they go on sale Monday at 10 a.m.," said Jay Alves, vice president of communications for the Colorado Rockies.

Not all of those tickets will go exclusively to Colorado fans, though. Sponsors, media, the team and team's families are all part of that equation.

Season ticket holders got first crack at series tickets, and they have the option of purchasing up to four. Already, many of them have posted them online, with prices in the Rockpile starting at $400.

This means, several Colorado fans could strike out in the ticket race.

"The bottom line is we're trying to get the most tickets to the most fans. This is the best way to do that," said Alves.

Fans are also worried scalpers and ticket brokers will have an unfair advantage in obtaining the tickets.

"Doesn't matter if they're in the box office or online, the scalpers are going to find a way to get tickets one way or the other," Alves said.

This isn't the first World Series team to sell the event's tickets online. A Major League Baseball representative said the Detroit Tigers sold them online last year and so did the Chicago White Sox in 2005.

Still, people like Ferrrari said while they are disappointed, they aren't discouraged.

"I'll absolutely try. I am borrowing several computers from friends. I'll do whatever I can, but I don't have a good feeling about it," said Ferrari.

Tickets go on sale Monday at 10 a.m. They can be purchased at www.coloradorockies.com
