Calculations!
Every year, some players start hot, others start cold. In the past, when a player had a high BABIP to start the season, we said, “Oh, well he’s lucky. His numbers will come down.” But now we can say with greater certainty, using Fielding Independent wOBA (or FI wOBA), what a player’s wOBA would actually regress to, given their performance in other areas.
Let’s look at the top five BABIPs in the league with FI wOBA regressed to career BABIP rates (or CaB-FIw for Career BABIP FI wOBA).
David Wright: .536 BABIP, .503 wOBA, .424 CaB-FIw
Even if/when Wright’s BABIP comes back to his career .342 BABIP, his peripherals are off the charts. He is on pace for 30 homers, which is nothing miraculous for Wright, but he is also walking and striking out at a 12.5% rate.
Will that kind of patience continue? Eh, probably not to that extreme, but it certainly means Wright is seeing the ball well right now and could be poised for a really good year.
