When the famed Baseball Abstract came out in the 1980’s, Bill James introduced the concept of OPS, writing that a player was a great offensive player if he could get on base 35% of the time while maintaining a .450 slugging percentage.
The reasoning was the player had the ability to get on base frequently and the slugging percentage measured how the player could advance runners, getting extra base hits, which is measured by slugging.
That made an 800 OPS the gold standard for hitters. That number started to be regarded as the measure of offensive success, but that led to younger baseball analysts thinking players with a .300 on base percentage and .500 slugging percentage were great hitters.
Those players generally tend to be guys who swing for the fences in most at bats, with high strikeout, low walk rates (hence the low on base percentage). Joey Gallo is the poster boy for us, with people telling us Gallo was an offensive force, piling up 800 OPS figures with batting averages of .209 (.333 OBP, 2017) and .206 (.312 OBP, 2018).
We know it is not fashionable to say this anymore, but no one who hits under .220 is a good hitter.
In 2024, the major league average OPS is 714, an on base percentage of .313 paired with a slugging percentage of .401.
Just a few years ago, good teams had several players that fit the .350/.450 model. For example, the 2015 Kansas City Royals that won the World Series had Eric Hosmer, Alex Gordon, Lorenzo Cain, Kendrys Morales, and Ben Zobrist.
The 2016 Indians had Jose Ramirez, Tyler Naquin, and Carlos Santana who did it, while Jason Kipnis and Francisco Lindor were very close.
Right now, the Arizona Diamondbacks lead the majors in runs scored and they have three such batters: Ketel Marte, Jake McCarthy, and Joc Pederson. The Yankees have scored the next most runs and they have just two in Aaron Judge and Juan Soto.
We watch the Orioles when they were in town and thought their lineup was pretty solid top to bottom, but they also have only two in Gunnar Henderson and surprisingly Ryan O’Hearn.
This year’s Guardians’ team, 13th in the big leagues in runs scored have just one in Steven Kwan (382/480/862). The next closest is kind of a surprise in David Fry (369/441/810). The Guards are 17th in on base percentage at .310, just below the league average.
The reason for that is that Kwan and Fry are the only Cleveland players who can get on base at a 35% or better clip. Among players with over 200 plate appearances, they do have three hitters who are slugging .450 or better–Ramirez, Josh Naylor, and Kwan.
Our point is the Guardians do not have a lot of real good hitters and the offense could be better if they had more hitters who got on base more often. On the other hand, the art of getting on base seems to be on the decline in the sport, and that’s a shame.
As James also said, the game is measured by the number of outs, not a time clock (pitch clock not withstanding). A 1.000 slugging percentage can be achieved by going 1 for 4 with a home run. If you have a 1.000 on base percentage, your team keeps batting in the first inning.
