There’s no one way to hit well, but there is one constant in hitting: batters swing too often. The intuition behind that fact isn’t hard to get to: if you swing at a pitch outside the zone, you’re taking a ball and turning it into weak contact (it’s hard to hit pitches outside the zone with authority) or a strike — that’s bad! If you swing at a pitch in the zone, you’re turning a strike into either a strike (if you miss) or contact. Swinging is so bad outside of the zone that it overwhelms the advantages of hacking in it.
I don’t mean to imply that this should extend to logical extremes — you can’t literally never swing — but the numbers are clear. In 2020, batters were worth 3,030 runs below average when swinging. They added the same amount when they didn’t swing. This isn’t a fluke: batters have already added 1,350 runs relative to average by taking pitches this year — you guessed it, they’ve cost themselves as much by swinging. In every full season since the advent of pitch tracking in 2008, swings have cost offenses at least 6,000 runs. It’s just a fact — hitters swing too frequently.
José Iglesias has probably never heard this advice. He’s in the midst of one of the swing-happiest seasons of recent memory, and he’s doing it in exactly the way that worries you — a mountain of chases. There’s just one twist — it hasn’t sunk him just yet, despite everything I said up above, and it’s fascinating seeing him survive.
The top of the chase rate leaderboard is filled with powerful hitters. Salvador Perez leads the way so far, with a 49.1% swing rate on pitches outside the zone. Luis Robert is in second. Javier Báez is in the top 10, as is Nick Castellanos. I don’t mean to say that you can’t be a good hitter when you get fooled that often — all of the batters I named are having good years. They’re producing in a particular way, though: plenty of misses, but loud contact when they do connect. Read the rest of this entry »
