SAN ANTONIO — Major League Soccer commissioner Don Garber will travel to San Antonio on Tuesday, where he will meet with Mayor Julián Castro and Scorpions owner Gordon Hartman to discuss the city's prospects of earning an expansion bid in advance of Wednesday's exhibition match between Mexico and South Korea, a league representative said Monday.

“He's certainly aware of growing popularity of the sport in San Antonio, and he's excited to learn more during the visit,” MLS spokesman Dan Courtemanche said.

“Clearly the Scorpions have been a tremendous success at the lower divisions, as illustrated by their strong support. It's something all of us in the American soccer community have noticed.”

MLS plans to add five expansion teams by 2020 for a total of 24. New York FC and Orlando City SC are slated to join in 2015, at which point the league will number 21 clubs.

Miami and Atlanta widely have been reported as strong possibilities to follow. Sports Illustrated reported last week that both Minnesota United, like the Scorpions a member of the North American Soccer League, and the NFL's Minnesota Vikings are gearing up for competing bids.

Hartman and Castro deferred comment until after meeting with Garber.

Garber had been slated to meet with Castro in New York City in November, but was forced to cancel.
