The Mets went into Tuesday night’s game against the Braves having hit 34 home runs in their last 16 games after hitting only two in their first eight.

The Braves have hit five all season. Now you know why manager Terry Collins is smiling.

“I don’t think you can predict this kind of power, especially in the early spring,” Collins said. “With the weather conditions, with the cold. I think obviously the one factor that has changed it is the power that Neil Walker has shown. We thought he was going to hit 15 homers, but spread out. We look at the first month and he’s got nine already.”

Walker, who led the club in homers going into Tuesday night, isn’t the only Mets hitter who has caught the power bug.

The Mets were fourth in MLB with 36 home runs. But since April 15, the Mets led the majors with 34. They had hit back-to-back homers five times, which was tops in the majors, after doing that eight times all of last season.

On Monday, the Mets had three home runs in the first inning (David Wright, Yoenis Cespedes and Lucas Duda). Overall, the Mets had outscored opponents 21-3 in the first inning.

“I think a lot of guys, they feed off each other,” Collins said. “It’s not that they just go up to hit home runs. I think they’re going up there with a real plan to try to put as good a swing on the ball as they can and it’s starting to pay off. We certainly could never have predicted the amount of home runs we’ve hit this early.”

Trainer’s room

Collins said Travis d’Arnaud (right rotator cuff strain) is continuing to rehab in Port St. Lucie, Florida, but has not started throwing yet. D’Arnaud is eligible to come off the disabled list on May 11.
