Major League Baseball's owners have unanimously approved private-equity billionaire David Rubenstein as the new owner of the Baltimore Orioles.

The accelerated sale, which will eventually give Rubenstein and his ownership group 70% of the Orioles, transferred control of the team to him less than two months after he agreed to buy it from the Angelos family.

The Oakland Athletics and their design teams released renderings Tuesday of the club's planned $1.5 billion stadium in Las Vegas that show five overlapping layers with a similar look to the famous Sydney Opera House.

The A's hope to move into that 33,000-seat domed stadium in 2028, depending mostly on the construction timeline. A glass window beyond the outfield provides an outdoor feel with views of the Las Vegas Strip.
