You don't have to resort to saber stats to say Trout had a better year. Just looks at traditional things like runs, double plays hit into, steals.
AVG HR RBI OPS R GDPs SBs
Cabrera: .330 44 139 .999 109 28 4
Trout: .326 30 83 .963 129 7 49
Look at the runs Cabrera wiped off the bases with those GDPs. FWIW, Trout beat Cabrera on OPS+, 171 to 166. OPS+ is a park adjusted number.
And for those who say Cabrera had no one around him, have you seen what Austin Jackson all year at leadoff and Quintin Berry and Andy Dirks did once they settled on them as #2? He had ducks on the pond all the time. It's a farce to say that he lacked RBI opportunities. Heck, Adrian Gonzalez was probably more efficient at knocking in runs (I'll leave someone else to chase down that stat).
Cabrera simply did not have as good an offensive year as Trout, and offense is the only basis for saying he had a better year. Also, for those of you saying Detroit had a cruddy team around him, who was the consensus pick in the AL
East Central before the start of the year?
