The Oakland Athletics are firmly headed for Las Vegas after Major League Baseball team owners unanimously approved the sport's first relocation since 2005 on Thursday.
It will be the A's fourth city — from Philadelphia to Kansas City to Oakland to Las Vegas — the most in baseball's history.
Here's a look at Major League Baseball teams that have moved cities since 1953.
TBA: Oakland Athletics move to Las Vegas
After years of complaints about the Oakland Coliseum and an inability to gain government assistance for a new ballpark in the Bay Area, the A’s plan to move to a stadium to be built on the Las Vegas Strip with $380 million in public financing approved by the Nevada government. The A’s lease at the Coliseum expires after the 2024 season and it remains unclear where the team will play before a new ballpark opens, in 2027 at the earliest.
