The Tornado

Almost every year since entering the 21th century, there were always some guys playing surprisingly well and their numbers just explode from their established level. Some of them did acheive a new level of ability and become a better player since, and there're also some so-called one-year wonders. Here's the list:

Rich Aurilia, 2001. Absolutely a fluke and one that cost Seattle 2M and oh btw, Carlos Guillen.
Bret Boone, 2001. Kind of a fluke, but he surely reached a legitimate new level of ability since then.
Luis Gonzalez, 2001. A Brady-Anderson style fluke.
Esteban Loaiza, 2003. Loaiza?? I thought that one was Oswalt.
Jose Guillen, 2003. Boonesque season.
Melvin Mora, 2003. How'd ya do that??
Carlos Guillen, 2004. Guillen+2M for Ramon Santiago and Aurilia. Good move, Bill.
Adrian Beltre, 2004. Looks like he's trying to win a fluke of the year award.
Ben Sheets, 2004. Right behind Adrian Beltre.

It's 2005 now, and we've got Brian Roberts, Derrek Lee and Bret Myers so far.

Brian Roberts
A career .277/.343/.394 hitter who's batting .368/.449/.642 this year. Geeeezz!!!

Derrek Lee
Yes, I knew that Derrek had always been a decent hitter, but .385/.470/.712??

Bret Myers
Ben Sheets 2005 version. Is it a fluke? I don't know. Of course he's got great talent and I always think he could do better. But remember that Seattle's 3rd baseman also got great talent, and everybody thinks that he could do better.
