An investment group that includes ex-Dallas Mavericks owner Mark Cuban has bought a minority stake in the Athletics in anticipation of their move to Las Vegas in 2028. Thursday’s announcement by Harbinger Sports Group did not say what percentage of the Athletics it had acquired. Cuban is the general partner and president of the Atlanta-based group. John Fisher is the majority owner of the A’s and is overseeing construction of a $2 billion, 33,000-capacity domed stadium on the Las Vegas Strip. The Athletics are currently playing in West Sacramento, California.
