The New York Mets refuse to play Gavin Cecchini, even though it makes sense to do so. He could be the future of the second baseman of the future, but he only has 21 career at-bats in the majors.
Cecchini oozes potential and has proven to be a much better defender at second base than he was a shortstop. But there is no possible way that a team hoping to make the playoffs in 2018 is going to bank on a player with so little big league experience to be a starter.
