JABO: The Rarity of Josh Donaldson’s Late Ascension
In some seasons, the Most Valuable Player award is a close race between a few worthy position players with a pitcher thrown into the mix if the circumstances align. This year, in the National League, the voting was unanimous for the MVP, and for good reason. In the American League, there were only really two serious candidates for the award, with one fact underlining that point: in MVP voting, each voter ranks players from one to ten, and this year in the AL, every ballot except for one had either Mike Trout or Josh Donaldson in first or second place.
Given that there were only two serious candidates in the AL, there was a fair amount of discussion about who was the worthier of the two players. We could say this was a battle of statistics versus context: a better statistical season (Trout) versus the offensive lifeblood of a playoff-bound Toronto team (Donaldson). Defensively, Donaldson had a better season, but Trout was clearly superior on the offensive side of the ball. Take a look at their full stats side-by-side (wRC+ uses 100 as league average, while UZR is how many runs better the player was than a league average defender):

| wRC+ (Offense) | UZR/150 (Defense) | WAR | |
| Mike Trout | 172 | 0.3 | 9.0 |
| Josh Donaldson | 154 | 9.8 | 8.7 |
In the end, the context that is often added to the MVP award won out: Donaldson led his Toronto team to the playoffs after the city had endured a 21-year postseason drought, compiling an incredible offensive and defensive campaign in the process. As is so often the case, there was no true right or wrong answer on who should have won the award; it was close enough to where both players could have deserved it, and it was a matter of opinion that separated them. When all is said and done, baseball is about winning games, however, and Donaldson benefitted from being a key piece of a team that won more games than Trout’s Anaheim Angels.
Discussing the worthiness of each player winning the AL MVP has already been covered at length. If you’ve paid attention to this award season, you probably know the arguments for and against both Trout and Donaldson: we’ve even recapped a few of them here. What is well-known is who Donaldson currently is. What is less-known is who he Donaldson was, and where he now stands among historical MVPs. In context, who he was is a huge part of the story, and we’ll see that it’s pretty rare that he turned into who he is.
