More than half of Major League Baseball's teams have pledged to pay baseball operations staffs through at least the end of May, according to sources.

However, a number of large market clubs -- the New York Yankees, Los Angeles Dodgers and New York Mets -- have yet to insure pay through May.

Rob Manfred told managers, coaches and other baseball operations workers that he planned to suspend their Uniform Employee Contracts on May 1, according to correspondence obtained by ESPN.
