I wonder how good Giambi is going to be. Clearly, he was a pretty good hitter before he started taking steroids, but what will he do this season?
Looking at his career numbers, look at the increase in his slugging percentage between 1999 and 2000. He went from good to ridiculous. So assuming he gets off to a decent start, I'd expect him to hit about 30 homers, drive in maybe 100 runs. A pretty good offensive first baseman, but nothing spectacular. He should still have a good eye and get on base a lot. Of course, if he has a slow start, or if the withdrawal from steroids has more serious effects, all bets are off ("Hello, Tino Martinez!").
There's also Barry Bonds' ex-mistress/girlfriend, who's claiming he started taking steroids around 1999-2000. That makes sense too. Look at his career numbers. Big jump in slugging percentage between 1999 and 2000, and an enormous one between 2000 and 2001. Homers went from 34 in 1999 (note, this was an injury shortened season) to 49 to 73. Looks like steroids to me.
