Mets first baseman prospect Peter Alonso didn't appear in Sunday's Futures Game until the fifth inning, but before the game, he put on a clinic.
Alonso, who has hit 21 home runs in 88 games across the Double-A and Triple-A levels this season, put on a show during batting practice. He competed with five players in a pregame contest: the Reds' Taylor Trammell, Brewers' Keston Hiura, Cardinals' Andrew Knizner and Orioles' Ryan Mountcastle.
And Alonso won.
Competing in the final group, Alonso "was the standout among standouts," Baseball America's J.J. Cooper wrote.
One of Alonso's homers "cleared the left field stands," while another bounced onto the concourse over the left-center field fence.
"Alonso showed the most impressive raw power during batting practice," Cooper wrote. "We have received multiple reports that his exit velocities throughout his minor league are top tier. We saw why on Sunday."
The 23-year-old Alonso thrived with Double-A Binghamton at the start of the season but has struggled since being promoted to Las Vegas.
In 65 games with the Rumble Ponies, Alonso hit .314 with 15 home runs and 52 RBIs, however he has hit just .190 with six home runs and 23 RBIs in 23 games with the 51s.
