No surprises here. Honestly, it is impossible to even make a case for any other rookie in the top spot. What Mike Trout has done in 2012 is absolutely unbelievable. His offensive numbers are so impressive in so many categories that I don't even know where to begin.
I'll start with runs scored; Trout leads all of baseball with 87 runs scored, even though he has only played in 88 games!
This obviously shows that he can get on base, as he has an unbelievably high OBP of .409. That is good for third the AL. Trout not only walks at the plate a lot, but hits for an incredibly high average; he is currently hitting .346, which leads the AL by 20 points. In fact, Trout has led the AL in average for much of the year now.
Not only does he hit for average, but an incredible amount of power as well. He currently has 20 home runs, despite playing fewer than 90 games. He also has great speed, as he leads the majors in steals with 36, and has only been caught three times. His five triples are pretty impressive as well.
Trout is also a great defensive center fielder, making circus catches (seemingly) every few days.
Oh, and he just turned 21 on Tuesday. Trout could win the Rookie of the Year award by the widest margin ever, and it would be much deserved. I haven't been watching baseball as long as most people, but he is, by far, the best rookie I've ever seen.
He is so good that he has become a legit contender for MVP. Although I still think he trails Miguel Cabrera for the award, I would have no problem calling him second in the race at this point, even ahead of a guy like Josh Hamilton.
