Jay Bruce avoided using his first baseman’s glove during spring training and says he would be surprised if it’s needed during the regular season.

“I don’t even think about it,” the Mets outfielder said.

But a lackluster spring training by veteran Adrian Gonzalez, who is attempting a return after missing most of last season with the Dodgers because of back issues, coupled with Dominic Smith’s largely inactive camp, has at least raised the alarm level about the Mets’ first-base situation. Smith played only one exhibition game and has been sidelined for the past month with a strained right quadriceps. He will begin the season at Triple-A Las Vegas.

Bruce played 11 games at first base for the Mets last season before he was traded to the Indians in August. His only previous activity at the position consisted of three games with the Reds in 2014.

“If they need me to work on it, then we’ll do it,” Bruce said. “I would work at it and be as ready as I can be. We’ll be all right, though, and if we aren’t we’ll still be all right.”

The 35-year-old Gonzalez batted .207 in the Grapefruit League with one homer and three RBIs. It’s expected that Gonzalez will begin as the primary first baseman, with Wilmer Flores playing against most lefties.

“[Gonzalez] just has to stay on the field,” Bruce said. “I think he will be fine. He didn’t have the spring training he would want, I don’t think, but he started swinging the bat better at the end, and he doesn’t need to come in here and prove he can hit, because he can hit, There is no question about that.”

Seth Lugo pitched five innings in a minor league game against the Nationals in Port St. Lucie on Tuesday and allowed one earned run on six hits and one walk. The right-hander threw 73 pitches, in his final tune-up before facing the Phillies on Tuesday at Citi Field.

The Mets are asking fans attending Thursday’s opener to use mass transportation because of the capacity crowd expected.
