Fans have snapped up all of the free vouchers to gain access to Minute Maid Park's viewing party for tonight's World Series game.
The Astros could win their first-ever title when they play the Dodgers in Los Angeles this evening.
The club has been offering free admission to watch all playoff road games on Minute Maid Park's big-screen scoreboard. The vouchers have been available only on the team's web site.
By Thursday morning, the vouchers were all gone.
