"A baseball team has about 4000 balls in play against them every year. The number varies widely around that figure, but it’s a good round number for our purposes. The A’s turned 2.5% more of those balls into outs in 2018. That’s 100 outs instead of hits, mostly singles, but enough doubles and triples to leave a mark. That’s how you allow 150 fewer runs year over year with just a small change in strikeout and walk rates."
