The moves were made following a 6-5 loss to the Saint-Louis Cardinals that dropped the Mets to 11-12.

Several accomplished hitters have gone on slow starts, including $ 341 million newcomer Francisco Lindor, who has been untouched in his last 25 at home and at bat .163 overall.

Hugh Quattlebaum, Minor League Strike Coordinator, and Farm Manager Kevin Howard, will join the Major League coaching staff to replace Davis and Slater, respectively.
“It was a tough decision to make,” said interim general manager Zack Scott. “It’s not 23 games results.
“We just felt that the players needed a different level of support and maybe different skills were built into the mix. “
Scott said it was a baseball operations decision and team president Sandy Alderson agreed.
“These are not recent results. This is the process behind the scenes, ”Scott said. “It’s too early to overreact to small sample results. ”
