Cover the Red Sox for a year and you'll spend a lot of time staring at Baseball-Reference, the pre-eminent site for the kind of stats you would've found on a Topps card in 1986, as well as many of the advanced numbers that have transformed the modern game.
Over the course of a season, some numbers will occasionally jump out at you. Here are five, from lowest to highest, that caught my attention in 2019.
.001 — The difference in OPS between Rafael Devers (.916) in his superstar breakout year and Mookie Betts (.915) in his lackluster MVP follow-up. Anyone who watched the team knows that Devers was the more impactful offensive player, especially from May through July, when the Red Sox still believed they had a shot at the playoffs. And yet when all was said and done, their numbers were virtually identical. It turns out that context matters.
3 — Hits for Dustin Pedroia since the start of 2018. He's had just 31 at-bats in that span, but that has been enough to drop his lifetime average from .300 to .299. He's almost certain to become a victim of the Jim Rice Effect. The Hall of Fame slugger was a .300 hitter for almost his entire career, dropping below that threshold on May 5, 1989. He played only 29 more games, and finished at .298. Let the record show that Pedroia was still a lifetime .300 hitter (technically .299535, but baseball rounds up), until grounding to short to lead off his penultimate game against Baltimore's Dan Straily. If this is it, he'll finish his career two hits shy of .300.
10 — Wins in Brandon Workman's out-of-nowhere dominant season, which saw him become the first pitcher in history to follow a 1-10 season (in 2014) with a 10-1 campaign. Only 55 pitchers since 1900 have won no more than one game while losing at least 10. Even rarer is the inverse, which has been done 21 times. Workman is the only pitcher to appear on both lists.
15 — Andrew Benintendi home runs since the second half of 2018. Benintendi entered the 2018 All-Star break with 14 bombs and nearly made the All-Star team. He has suffered a mystifying power outage since, managing just two homers in the second half of 2018 and 13 last year. That means he has dropped from 14 homers in the first 91 games of 2018 to 15 in the 195 games since.
21 — Months that Jackie Bradley Jr. has hit under .220 with the Red Sox. Compare that to three crazy outliers that saw him hit over .350 and it becomes clear how misleading it is to call him streaky, a term that suggests roughly equal performance in both directions. Take away August of 2015 (.354), May of 2016 (.381), and June of 2017 (.353) and Bradley's career average dips from .236 to .221, which helps explain why the Red Sox are likely to move on from the defensive whiz this winter.
