Major League Soccer hopes to pick a 30th team by the end of the year.

"San Diego and Las Vegas are the most likely,'' MLS Commissioner Don Garber said Wednesday during a kickoff event at the league's new television studio built together with Apple TV.

"The 30th team will come at some point soon,'' Garber said. "We'd like to get that announced by the end of the year.''

He mentioned Detroit; Phoenix; Sacramento, California; and Tampa, Florida, as other expansion possibilities.
