Callis: Alonso Might Be Baseball’s Best 1B Prospect

In his MLB Pipeline Inbox, Jim Callis addressed a number of topics regarding recent draft picks and their rankings within their new organizations.

When speaking about where Mets 2018 first round pick Jarred Kelenic now sits among the Mets rankings, Callis dropped this bombshell, “Alonso has posted impressive power numbers since signing as a second-round pick in 2016, already has reached Triple-A and can make a case for being the best first-base prospect in baseball.”

That is high praise indeed, but it is praise Peter Alonso has certainly earned with this play on the field. After hitting .314/.440/.573 with 15 homers and 52 RBI for Double-A Binghamton, Alonso was promoted to Triple-A Las Vegas.

In his first 12 games in Triple-A has struggled a bit, Alonso is hitting .222/.352/.444 with three homers and 11 RBI. He has also struck out 16 times in 45 at-bats.

Overall, June has been a struggle for Alonso with a .757 OPS and only four home runs in 87 at-bats.

In total, Alonso has made significant strides forward this season. Most notably, Alonso is sleeker, better in the field (though still below average), and he has been much more selective at the plate. With that selectivity, we have not only seen him draw more walks, but we have also been able to see him identify and absolutely crush his pitch.

While his play this season has been enough to potentially make him the top first base prospect in all of baseball, it was not enough for Callis to dub him the top prospect in the Mets farm system. That honor continues to go to Andres Gimenez, who has a 113 wRC+ as a 19-year-old in St. Lucie.

Callis has Kelenic ranked behind these terrific prospects as the Mets third best prospect in his unofficial rankings. As each of these players continue to develop, it will be interesting to see if these rankings change before the beginning of next season.
