How Likely Is a Triple Crown Winner This Season?

There are far better ways to evaluate offensive performance than the Triple Crown stats or whether a player leads the league in all three categories or not. But winning a Triple Crown, though not a gold star evaluative measure, is a lot of fun, and following a Triple Crown run is a family-friendly good time. It’s a rare feat to accomplish in baseball history, and while increased competitiveness and larger leagues make pulling it off more difficult, it can be achieved in both high-offense and low-offense seasons. It also puts you in the company of a lot of baseball greats, with every AL/NL Triple Crown winner having a plaque in Cooperstown except for Miguel Cabrera, who will almost certainly have his own five years after he retires.
Both Aaron Judge and Paul Goldschmidt look to be in realistic scenarios to win the Triple Crown. To get the exact projections, let’s look at them individually, starting with Judge, who has the simpler scenario.
(To get the probabilities, ZiPS uses the rest-of-season projections for every player, sims out a million seasons, and sees whose lines result in Triple Crown wins, if any. To get a more accurate gauge of what the probabilities are, ZiPS does not assume that the rest-of-season projection is necessarily the underlying ability of every player. In the case of Judge, for example, ZiPS estimates his underlying ability to hit homers over a three-week period as a distribution rather than a point. The generalized model ZiPS uses effectively replicates the number of streaks and slumps in reality over a short period; there’s a reason we have more consecutive hit streaks, homer streaks, and scoreless inning streaks than one would expect from a simple exercise of binomial hijinks.)
