Last two months of the season, Cabrera hit over his average and really piled on the RBIs and HRs.
Last two months of the season, Trout hit (a still respectable) .289 (I think).
One team made the playoffs through grinding down the stretch, the other team missed the playoffs. If Trout had put up stellar numbers at the most crucial time of the year (towards the end of the season), I'd still consider him a candidate. However, that was not the case.
