Mets overhaul the coaching staff, moving on from pitching coach Jeremy Hefner while keeping manager Carlos Mendoza amid a contentious season. Hitting coaches Jeremy Barnes and Eric Chavez and third-base coach Mike Sarbaugh won’t return; bench coach John Gibbons resigns and catching coach Glenn Sherlock retires. Desi Druschel and Jose Rosado can explore other opportunities; Antoan Richardson, Danny Barnes and Rafael Fernandez are invited back. Peterson and Manaea showed promise, but pitching and defense hurt the club, with Soto’s megadeal towering over payroll.
