About 4,000 Texas Rangers tickets stolen from a vendor will have the bar codes changed to void them.
Metro Tickets in Dallas had a break-in through the wall of an adjacent business, KTVT reports. Police say the theft of about $140,000 worth of tickets was discovered last week as the season was starting.
Metro Tickets owner David Christopherson said the tickets are for games in July, August and September.
Christopherson warns that the tickets probably will be offered online or scalped and buyers should use legitimate brokers.
Rangers spokesman John Blake said team officials can check tickets to make sure they are legitimate.
The Rangers, unbeaten in their first six games, will visit the Orioles on Friday night.
