This has been an exciting year for rookie performances. Juan Soto has looked like the best teenage hitter in history, Ronald Acuna has helped lead the Braves to a (surprising) lead in the NL East, and Shohei Ohtani has short-circuited our understanding of player value with his two-way achievements. Rookies have always been a key component to baseball’s excitement, and this year’s crop is no exception.
Now, quick: what player leads rookies in second-half WAR? If you guessed Acuna, congrats! Acuna has caught fire, putting up a 190 wRC+ and 3.4 WAR since the break — second-best in baseball behind Matt Chapman’s 3.7 mark during that timeframe.
Let’s continue, though. Who’s second amongst rookies since the break? Soto? Sorry, no. Ohtani? Nope, not even after accounting for his contributions on all sides of the ball. It’s not the workman-like Brian Anderson, nor is it defensive wizard Harrison Bader. No, second among rookies in WAR during the second half is New York Mets second baseman Jeff McNeil. For some, perhaps that makes sense. For many, though, the likely response is, “Who?”
That’s understandable. Unless you’ve watched a Mets game since July 24th — and let’s be honest, why would you if you lived outside the New York MSA? — you’ve probably not heard of McNeil. Even if you were a prospect hound, McNeil could have evaded your eye. He didn’t appear on prospect lists for the Mets here at FanGraphs, at Minor League Ball, or Baseball Prospectus. At FanGraphs, only the enigmatic Carson Cistulli mentioned McNeil in an early July edition of the Fringe Five.*
*Since this article came out, it has come to my attention that several articles focused on or mentioning Jeff McNeil have been written by several authors. Among them include the Baseball Prospectus and Baseball Prospectus Mets prospect writers Jarrett Seidler (May 2018), Jeff Paternostro, and Alex Rosen (May 2018). Jeff’s coverage of McNeil in particular goes back as far as McNeil’s second season in 2014. This oversight was completely accidental on my part and not meant to disregard or disparage their work or the work of anyone else who has written about McNeil in the past
For a Mets fanbase that has observed the front office regularly block prospects in favor of flawed veterans — at least they finally freed outfielder Brandon Nimmo — it has to be mildly gratifying to see a young player getting reps in the waning days of the season. McNeil is not only second in WAR amongst rookies in the second half, he is 13th among all hitters by the measure.
Given McNeil’s lack of obvious tools, there’s still reason to doubt that he can put together a substantive major-league career, let alone sustain the pace he’s established since July. Despite these concerns, however, it’s encouraging that the Mets have continued to give McNeil — and Amed Rosario and Nimmo — sufficient playing time to earn a place on the big-league club.
