According to a team insider, it's important for the New York Mets to avoid an extra year of arbitration eligibility for pitching prospect Zack Wheeler.
In March, an executive with another club estimated a team would need to wait until June 15 to call up a prospect in order to delay arbitration eligibility by a year.
The Mets, internally, right now estimate the imprecise date a little sooner -- from the final days of May to as late as June 10.
