Business is good at Amazing Tickets, a resale marketplace for event tickets in Mayfield Village, where Cleveland Indians tickets are being sold online.
"Interest is at a red hot level,"said Mark Klang, company owner.
His website, Indianstickets.com, is swamped with baseball-loving visitors now that the Cleveland Indians have clinched home-field advantage in the American League Division Series.
Klang told Fox8's Lorrie Taylor fans have been shelling out big bucks to see the Tribe's first two games against Boston on Thursday and Friday.
The cost to simply get inside is $75 for a standing room only ticket that typically runs about $35.
$65 reserve seats in the upper level behind home plate are going for as much is $125 a ticket.
Lower-level seats closer to the infield that cost $100 are $250 apiece.
Front row seats over the dugouts are bringing $700 when they typically cost closer to $250.
If the team makes it to the American League Championship series, that inflated price of $700 a seat will be closer to $1500.
Klang said he expects tickets to be sold out by Tuesday afternoon.
