Rob Manfred admitted that expansion is on Major League Baseball's near- to mid-term radar.

First of all, Manfred said the stadium situations in both Oakland and Tampa Bay will have to be resolved before expansion is seriously considered.

"I think we have some great candidates," the commissioner said. "I know the mayor of Montreal has been very vocal about bringing baseball back to Montreal. It was not great when the Expos left. The fact of the matter was baseball was successful in Montreal for a very long time. Charlotte is a possibility. And I would like to think that Mexico City or some place in Mexico would be another possibility."

Major League Baseball hasn't expanded since the Tampa Bay Rays and Arizona Diamondbacks jumped on board in 1998.
