Michael Fulmer's Rookie of the Year win means he owes Justin Verlander dinner -- apparently

On Monday, MLB announced that Dodgers shortstop Corey Seager and Tigers right-handerMichael Fulmer are the National and American League Rookies of the Year, respectively, as voted upon by the BBWAA. 

Fulmer, 23, racked up 132 strikeouts en route to his honor, notching a 7.5 K/9 ratio along the way -- a few behind rotation mate Justin Verlander and his 10.0 K/9 rate. It was also more than Verlander's in his Rookie of the Year season in 2006 (6.0).

Congratulations indeed, "Roy."
