WASHINGTON -- Since its creation in 2015, "Play Ball Summer" continued to grow into one of Major League Baseball's most successful youth initiatives by working in conjunction with the United States Conference of Mayors. Last year, a record number of mayors hosted a record number of children at Play Ball Summer events in nearly all 50 states and Puerto Rico.
That prompted Commissioner Rob Manfred to call the partnership between MLB and the U.S. Conference of Mayors one of the best decisions he has made during his tenure, as he announced on Wednesday the partnership will be renewed through 2020.
