The A’s are set to make their regular-season debut in Las Vegas next season as their long march to the desert continues. The team, which moved from Oakland to Sacramento last offseason, plans to play two interleague series in the Las Vegas area in June at their Triple-A affiliate’s stadium in Summerlin. They’ll host the Brewers at Las Vegas Ballpark for three games from June 8-10 and the Rockies will visit from June 12-14. The Athletics’ 75 remaining home games will be played in West Sacramento at Sutter Health Park, the home of the Giants’ Triple-A affiliate, where they are playing their home games this season. Las Vegas Ballpark has hosted several A’s spring training games in recent years, but this would be the team’s first regular-season series there. Owner John Fisher’s long-held ambition of opening a stadium in Vegas is optimistically set for 2028 after a ceremonial groundbreaking at the Tropicana site in June. The funding for the stadium remains somewhat up in the air as the stadium is now expected to cost roughly $2 billion, Fisher told the Nevada Independent last month. The Gap Inc. heir who moved the team from Oakland after 57 years at the Coliseum has said he will pay roughly $1.1 billion of the construction cost, and in June hired a firm to help sell Major League Soccer’s San Jose Earthquakes, which he also owns. The A’s play the Giants on both ends of the former Bay Bridge Series: In Sacramento on May 15-17 and at Oracle Park on June 23-25.
