Betts got 28 out of the 30 votes. Yelich got 29.
Yelich was the unanimous choice among position players. The other first place vote went to a pitcher (deGrom). Javier Baez was named on all 30 ballots, but none of them placed him first.
Yelich led the league in the key Sabermetric stats (OPS and WAR), and many of the traditional stats as well (slugging and batting averages). After the All-Star break, Yelich hit .367 with 25 homers. He totally carried the team during their final stretch drive, batting .370 with 34 RBI in the final month. In the final eight-game winning streak that carried the Brewers past the Cubs to the division championship, Yelich batted .458 with a .649 on-base percentage, and he averaged more than two RBI per game.
Betts and Mike Trout got almost all of the 1-2 votes in the AL. Betts was first or second on every ballot, while Trout was on 25/30.
