The Mets intend to rethink the way they use a pitching staff that disintegrated during a 92-loss season, sources have told Newsday. It’s a philosophical shift that will shape their decisions as general manager Sandy Alderson begins a critical offseason reboot. With the exception of Noah Syndergaard and Jacob deGrom, Mets starters may be shielded from facing lineups more than twice in a game, mirroring an industry-wide trend, according to a source. The adjustment comes after a season in which team officials watched many of the Mets’ starters fade badly as they pitched deeper into games. Fewer innings on a nightly basis from the starters means a greater emphasis on the bullpen, and sources said the Mets will look to establish a norm of carrying eight relief pitchers, one more than the standard seven. Pitching will be the focus as the Mets begin retooling a team they believe will compete next season. A strong presence for the bullpen and a sturdy innings-eater for the rotation are among the items on the to-do list, according to sources. Last season, the Mets posted a 5.01 team ERA, second worst in the National League behind only the Reds. Now the Mets again may have to deal with innings limits, as every starter except for deGrom had his season workload impacted by injury. Positional versatility also will be highly valued as the Mets look to fill holes in the lineup, a source said. An extra reliever means one fewer roster spot for the bench, which places even more importance on the ability to play multiple positions.
