The Mets, as a team, have not had an impressive offensive season so far. Through Sunday’s game the team has scored 635 runs, 12th in the NL. However one Met is high on many of the statistical leaderboards, and by one advanced metric he is having the best batting season of anyone in the league.
That player is Brandon Nimmo, who has blossomed this year as an everyday corner outfielder/sometime center fielder. In 128 games, he has assembled a slash line of .266/.396/.496, accompanied by 17 homers. His OPS figure is .892. Good numbers, certainly, but the figure that really stands out among these stats is that OBP. He ranks fifth in the league in that category, ahead of players like Bryce Harper and Freddie Freeman.
There are other leaderboards that Nimmo ranks high on, including 21 HBP, 1st in the league and a significant factor in Nimmo’s high OBP. Nimmo has pounded eight triples, tied for third in the league. In offensive WAR, Baseball Reference lists NImmo with 4.6, ninth in the league.
As noted in the first paragraph, there is an advanced metric that Nimmo leads the league in. That would be Baseball Reference’s Adjusted OPS+ stat, in which Nimmo is credited with a 151 figure, good enough for first in the league.
Adjusted OPS+ is modified from OPS by factoring in the influence of park and league. Citi Field has depressed offensive production, even after the fences were moved in few years ago, and Nimmo’s first place rank in the Adjusted OPS+ category shows that in a neutral park, Nimmo’s OPS figure would be substantially higher than what it is.
It is interesting that in the most traditional of offensive stats, BA, Nimmo’s mark of .266 is fairly ordinary. Yet by that advanced metric of Adjusted OPS+, Nimmo actually leads the league. This has a bit of commonality with the season Jacob deGrom is having, whereby in the most traditional of statistics by which to measure starting pitchers, wins, deGrom has racked up just eight so far, a decidedly ordinary amount. Yet in more advanced pitching metrics, deGrom does much better. IN FIP he leads the league with a 2.05 mark.
I am not comparing the value of Nimmo to the team as opposed to the value of deGrom, no sane analyst would, deGrom is having an historic season. It should be noted that a cursory glance at the old school stat does not do justice to them, one needs to examine the advanced metrics.
Nimmo hustles, he can run, and he is proving to be a force at the plate. This is only Nimmo’s third season in the big leagues, and he has improved his SLG from .329 for his first season up to .496 in his current year, and most of his other stats have improved as well. It looks like he could be a fixture in the Mets’ outfield for many years to come.
