Would Peter Alonso Outplay Jay Bruce?
The New York Mets are a treasure trove of interesting case studies. They’re a large-market team run frequently like a small-market one, a club that doesn’t always seem to consider the present quality of the team when making decisions about the future, an organization whose various departments — medical, public relations, etc. — don’t always appear to interact. Whatever they are, the Mess are never boring.
Fresh off rumors that the team is interested in pursuing, for their next general manager, someone who is less reliant on data, the team has recently caused the internet buzz again by choosing not to promote the team’s top first-base prospect, Peter Alonso. My colleagues Jay Jaffe and Sheryl Ring have already addressed the service-time games that involve Alonso, but I think it’s interesting to also tackle the situation by looking directly at Alonso vs. Jay Bruce as a pure baseball decision.
It’s a completely non-controversial opinion that 2018 has been a monster season for Alonso, one that has given him real hype as a prospect, something that was not a foregone conclusion entering the year. Even the ZiPS projections for Alonso didn’t quite see this comping, ranking him as the No. 2 Mets prospect coming into the season, the No. 3 first-base prospect in baseball, and the No. 99 prospect overall — all of which I believe were the most optimistic forecasts. Alonso started off the season blazing hot, hitting .408/.505/.776 with seven home runs in April for the Binghamton Rumble Ponies. That performance led to a mid-June promotion to Triple-A Las Vegas. Alonso struggled early there, hitting .171/.330/.368 with 29 strikeouts in 76 at-bats for the 51s. That was extremely concerning in light of the fact that, at 23, Alonso was not a young player at Double-A, but he hit .297/.367/.676 with 17 homers in 182 at-bats after the All-Star break.
