ESPN's Keith Law doesn't think much of the trade: ] Luis Castillo might represent an upgrade over Ruben Gotay, and he might not. Castillo is a one-dimensional player whose game revolves around his speed. He's a classic slap hitter who can't even turn on average fastballs but who hits the ball on the ground and tries to slap harder stuff the other way and beat balls out with his speed. His speed has already started to decline; his range at second base, never great, is now poor, and he hasn't been an effective basestealer since 2004. He's the antithesis of everything the Omar Minaya's Mets do as an offensive club. Their best hitters -- Reyes, Wright, Delgado and Beltran -- all get on base, hit for power, and (except for Delgado) steal bases at high percentages. Whether he's really an upgrade depends on how much of Gotay's offensive outburst this season is real. Gotay's career was nearly derailed by the Royals' ridiculous policy of jumping players two levels or more to the majors before they were ready, a policy that fortunately seems to have ended with the hiring of GM Dayton Moore, but before that showed promise as a young infielder with plate discipline and some doubles power. The Mets are convinced that Gotay's defense isn't good enough to be an everyday second baseman, and he will never be better than average defensively at second, but he's better than Castillo is. Add to that the fact that Gotay has a little more thump in his bat, with a solid line-drive stroke that produces doubles rather than the groundballs Castillo hits, and it's really not clear that the Mets got better here. It's a bit worse if, as rumored, the Mets try to work out a contract extension with Castillo, because once his speed is gone, he'll be close to a replacement-level player. The Mets didn't give much up to acquire Castillo. Drew Butera is a catch-and-throw catcher with plus makeup and good bloodlines -- his father, Sal, played in the big leagues for the Twins and is now a pro scout with Toronto -- but he's not much of an offensive threat. He should play in the big leagues because of his defensive skills, but he's not a starter, even when he wasn't staring up at Joe Mauer on the depth chart. Dustin Martin was a senior sign out of Sam Houston State in 2006 and is an organizational player with a little bit of ability; there's an outside chance he could improve enough to become a 4th/5th outfielder in the majors.
