I just made two big trades, is my fantasy baseball team now a championship contender?

Well your team is good (although alex gonzalez should be nowhere near any fantasy, or even real baseball team, and jorge posada is probably gonna get hurt), but what struck me is the teixeira/ibanez trade. Of course the guy loves teixeira, he's one of the ten or so most valuable fantasy players. and ibanez is a very solid outfielder. Dan Haren is always way worse in the second half (his WHIP jumps up over 1.30 and his ERA is well over 4) so you should trade him away when he's on a hot streak sometime before the all-star game for a quality SS or catcher. crawfords good, although he doesn't contribute much in homers, RBIs or OPS. Also you may find that Aaron Hill doesn't have close to the kind of numbers he had last year, and yes get rid of Juan Rivera.
