Mike Trout has been an All Star in each of his seven full MLB seasons. He led the American League in fWAR in five of those seven seasons (four of seven by bWAR; led AL hitters in WARP in three of seven). During that period, he finished in the top two in AL MVP voting every season save his injury-shortened 2017 and won the award twice.
So far, 2019 looks like another MVP year for Trout, who received his eighth-consecutive All Star nod and has a commanding (roughly two-win) advantage atop all AL WAR(P) leaderboards. That Trout will win the award feels like a foregone conclusion, and it has for some time. Early in his career, though, Trout’s MVP candidacy was a contentious flashpoint for the battle between the respective adherents of “new” performance-valuation metrics and “traditionalists.” That conflict came to a head in 2013, when Miguel Cabrera repeated as AL MVP and Trout again finished second. Cabrera’s .348/.442/.636 line led the majors and represented an across-the-board improvement over his line in 2012, when he became baseball’s first triple crown winner in over forty years. On the other hand, Trout’s WAR mark clearly bested Cabrera in 2013 (10.2 versus 8.6 fWAR; 9.0 versus 7.3 bWAR), just as it had in 2012 (10.1 versus 7.3 fWAR; 10.5 versus 7.1 bWAR).
Ironically, Baseball Prospectus, long a leading publisher of work by adherents to “new” performance-valuation metrics, recently reversed course on the 2012 and 2013 AL MVP races after it incorporated changes made to its batting metric into its WAR model (i.e., WARP), acknowledging now that Cabrera really was a more valuable player than Trout in ’12 and ’13. Of course, these days, the fight between “traditionalists” and “sabermetricians” is over. In 2019, no one is arguing that Michael Brantley or Rafel Devers, the current respective AL leaders in batting average and RBI, deserve the league’s MVP award, for example. Part of that comes from the broader appreciation of the usefulness of advanced metrics, and part of that is because Trout is leading many of the traditional categories– at the moment, homers (42), OBP (.435), and SLG (.649)– too. Even if the analytical environment around baseball hadn’t changed, old-fashioned voters would have a hard time denying Trout his due in 2019. Does that mean that Trout has every vote locked up this year?
Stated otherwise, the question is whether there’s a good reason why someone would not vote for Trout as this year’s AL MVP. WAR isn’t everything, of course, but the current difference, by fWAR, between Trout and second-place Alex Bregman is Tim Anderson, or Whit Merrifield, if you prefer, or Blake Snell, last year’s Cy Young winner, all of whom currently have 2.5 fWAR. And Trout’s leads in homers and OPS fortify his position, with his positive contributions on defense and the basepaths rounding out a seemingly unassailable case. What more could he do?
The traditional MVP consideration never was just about individual numbers like batting average and RBI; voters also seemed to care about team-level winning. After all, baseball is a team sport in which the goal is for teams to win games and championships, and there is a conceptual sensibility to the notion that a player deemed “most valuable” would be one who translated his individual value into some significant measure of team value. Recall for example that, in 2012 and 2013, Cabrera’s Tigers were division-winning playoff teams that made deep runs while Trout’s Angels missed the playoffs and waffled around a .500 win percentage. If all of Trout’s good isn’t really doing the Angels any good, is he really the type of player we think of as an MVP? We can appreciate a superstar toiling in competitive obscurity, but does it make complete sense to bestow upon him or her the game’s highest individual honor?
Consider how infrequently postseason MVP awards go to players from losing teams. When it comes to formulating an MVP-award rubric, one can both prefer reliance on metrics that better account for individual performances and believe that the rubric should account for both team-success and individual-statistical components. In other words, the sabermetric revolution need not change what we’re looking for in an MVP even if it has changed how we decide if a candidate meets our criteria.
The good news is that there is a sabermetrically sound method to building an MVP-award analysis that accounts for both individual and team aspects. Continue reading
