2016 - Trout #1
2015 - Donaldson #2 (Trout was #1)
2014 - Trout - #2 (Kluber was #1)
2013 - Cabrera - #4 (Trout)
2012 - Cabrera - #5 (Trout)
2011 - Verlander - #1
2010 - Hamilton - #1
2009 - Mauer - #3 (Greinke)

Now there have been some silly votes. Victor Martinez finishing 2nd in the MVP in 2014, or Mark Texeira in 2009 (neither were in the AL Top Ten). But the writers have gotten smarter about the new tools.
If we go with bWAR it's Betts, Trout, Ramirez, Chapman, Lindor ...fWAR has a harder time with Chapman compared to the other 4 ... but again none of them are BAD choices. WAR is not a way to end the discussion, but a way to start it.
