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).

That's a one-two punch that misses a lot of bats, and, apparently, they had a friendly agreement in place should Fulmer win the award. 

Also, congrats to @MFulmer12 for being a finalist for #ALROY !! Winner buys dinner next year. 😜 @MLB

That led to this:

Or it could be one ROY buying another ROY a dinner a decade later. @MFulmer12 @MLB #goodluck #ivoteFulmer #ALROY

And then, after Fulmer did win the award, this:

I guess I owe @JustinVerlander dinner now. Thank you to everybody for a memorable season. Congrats to @ElGarySanchez and @TyNaquin as well

And this response from an obviously excited Verlander:

.@MFulmer12 yessssss. 💵💵💵 https://t.co/9Zl62Ssy5p

A free dinner's a free dinner! That's something everybody can support, right? Besides, it also earned Fulmer a new nickname from his veteran teammate:

.@MFulmer12 congratulations! Only get one crack at that award. Glad to see all of your hard work pay off! And now I shall call u Roy #ROY

— Justin Verlander (@JustinVerlander) November 15, 2016

Congratulations indeed, "Roy."
