ABC News reached out to Major League Baseball for comment but did not immediately receive a response.

The letter comes on the heels of Sanders tweeting his dissatisfaction with the move last week and it's potential effect upon his local Vermont Lake Monsters. Sanders' original tweet quoted a post authored by Washington Nationals pitcher Sean Doolittle, who also expressed his dismay at the potential restructuring. Doolittle, whose Nationals won the 2019 World Series last month, garnered attention earlier this month for declining to join his teammates on a trip to the White House to meet with President Trump following their championship victory.
