Nady, the X-factor

The Xavier Nady deal that sends an overachieving (breakout?) outfielder to the Yankees is baffling to me. Nady's hitting .330 with a .383 on base percentage, but he's already 29, and he's hit .281 for his career. It's safe to assume he'll fall back to earth a bit, and when a hitter changes leagues he is seeing new arms constantly. Couple that with the fact that Yankee Stadium has a deep left field, plus the fact that New York has pieces returning to replace Nady as a starter if he doesn't deliver, and I'd be worrying as a fantasy owner whether this guy can keep up the pace on what is to this point a career year.

Fantasy Impact: Nady might thrive in New York, but I'd say sell high. He's hit 13 home runs this season, which is nice, but there's going to be a lot of risk involved down the stretch. I'm never a fan of trade-deadline deals that involve hitters from outside the league. It's a lot to ask a guy to figure out an entire league of pitchers over just two months. Deal Nady, and watch your opponent suffer the probable fall.
