Is that in the outfield, or at 2b? I realize Mookie shredded AAA, but that's an extremely optimistic projection for any prospect.
Yeah, I had the same question myself. Not sure.
Though, to echo NotK, Mookie already has a 1.0 bWAR and a 0.5 fWAR. In 27 games. And in a majority of the games, Mookie was just learning a new position (his call-ups before this recent one), and he still is (so the defensive component may be skewed negatively at this moment).
Also bear in mind that when discussing Pedroia, a lot of his value is tied to his defense. Dustin Pedroia has a 103 OPS+ this year, with this slash line: 280/340/379.
Don't get me wrong, my bias believes he's the best defesive second baseman in baseball. But I'm also smart enough to realize that WAR relies on shaky defensive components. I believe I was reading in one of Keith Law's recent chats that someone was throwing out a +/- 2.0 margin of error, which would make the WAR stat useless.
Also, don't look at Pedroia's 5 year projections (he ceases being a 5 WAR player!)
