SAN DIEGO — The Mets’ investment in their bullpen this offseason has been light, and general manager Brodie Van Wagenen indicated Thursday that might not change.

After adding veteran starting pitchers Rick Porcello and Michael Wacha at the winter meetings, Van Wagenen said he’s comfortable with the bullpen as constituted. That means potentially keeping Seth Lugo and Robert Gsellman in relief roles, joining Brad Brach, who returned to the Mets on a one-year deal worth $850,000.

Lugo last season emerged as the Mets’ most dependable reliever, but Van Wagenen had considered adding him to the rotation after Zack Wheeler’s departure through free agency. Gsellman was also an option to fill that spot. Both are now considered starting pitching depth that will only be removed from the bullpen if there is a rotation shortage.

“We can bolster our bullpen by having Lugo and Gsellman now go back to the bullpen along with Brach if that’s how it shakes out in spring training,” Van Wagenen said. “It’s a good position to be in, and we will sort of adjust on the fly in terms of what other opportunities come in.”

Lugo, Gsellman, Brach, Edwin Diaz, Jeurys Familia and Justin Wilson figure into that bullpen mix. It’s also possible a starting pitcher — the Mets now have six — will be moved into a relief role. Wacha spent part of last season in the bullpen with the Cardinals.

The free-agent market includes names such as Dellin Betances and Will Harris, but Van Wagenen hinted he isn’t intrigued.

Last winter, Van Wagenen traded for Diaz and signed Familia to a three-year contract worth $30 million. Both flopped, leading to concern this offseason.

“We feel that the volatility in the reliever market, which we experienced last year, makes investment into that market a little bit riskier,” Van Wagenen said. “Right now we have six starters who all have fourth starter or better ability. That value versus investing in more volatile relievers with checkered track records, we feel like this is a better way to go.”
