The footsteps that Adrian Gonzalez and Dominic Smith hear aren’t going away.

After a red-hot April, top Mets prospect Peter Alonso has slowed down (somewhat) in May, but his bat is making noise.

Turns out, it’s hard to keep up a .408/.505/.776 slash line for an extended period of time. Alonso, a first baseman with Double-A Binghamton, is still hitting well, but his numbers have dipped to .275/.444/.478, with four home runs and 16 RBIs in 21 May games.

“He had an unbelievable month of April, but we have four months to go in the season,” Binghamton manager Luis Rojas said after his torrid first month. “We want to see the consistency. We want to see the adjustments the league makes to him, and we want to see how he adjusts.”

Now, it’s Alonso’s move. The University of Florida product has continued to show a sharp eye, with 16 walks to 18 strikeouts this month. So even if his batted balls aren’t always falling, he’s getting on base often.

The consequences here could come into play sooner rather than later for the Mets. Gonzalez is 36 and, though Smith has been expected to be the organization’s next first baseman, the 23-year-old has recently begun experimenting in the outfield at Triple-A Las Vegas. That could be an indication the Mets are looking for a way to fit both Smith and Alonso into their future — or that they don’t want Alonso blocked.

Thanks to his April, Alonso’s season-long numbers are still eye-popping — he’s getting on base at a .475 clip and has 11 home runs to his name.

“This is a guy who has a real quiet approach,” Rojas had said. “Not a lot of moving parts. Ready early, see the ball and hit it. Doesn’t overthink, doesn’t try to pick. He’s very secure with himself. He has a really strong hitting mentality.”
