No, James, Luis Arraez Shouldn’t Take More 3-1 Pitches

Last week, we got a mailbag question from James, whose glimpses of Luis Arraez during the World Baseball Classic left him looking for one weird trick to vault the three-time batting champion back up to his previous heights. I had so much fun answering the question that its word count moved it out of mailbag territory (non-Jay Jaffe division, anyway) and into regular article territory. The question was on the longer side, but here’s an abridged version:
If [Arraez] could wear a ribbon on his wrist to deter a bad hitting habit, would he be able to avoid something that drags him down?
My first idea was swinging on 3-1 counts… If he spit on 3-1 pitches habitually, until opposing pitchers caught on, what percentage of them would have landed him on first? What impact would that have on his OPS & WAR, and how would that impact his value and employability?
Could there be other commonplace opportunities that may be similarly exploited?
I realize James is asking for a more specific answer here, but I want to start with the overview, because at this point, I think people may have forgotten that once upon a time, Arraez actually had great plate discipline. From 2019 to 2022 he ran a 24% chase rate and a 9% walk rate. That walk rate was 5% higher than the league average. From 2023 to 2025, he had a 34% chase rate and a 4% walk rate. That walk rate is now a staggering 45% below the league average! Over the same period, Arraez’s swing rate on pitches inside the zone fell from 65% to 62%. He wasn’t just chasing more; he was making worse swing decisions all around. That’s a lot of shifts in the wrong direction, and even though Arraez also cut his strikeout rate nearly in half, his wRC+ dropped from 123 to 109. Read the rest of this entry »
