Joe Posnanski, who just keeps churning out interesting articles, writes that the Sox may not have secured the division with their one-day trade binge:

Of course, you never know. This just might be the move that puts the White Sox over the top. The "Baseball Tonight" people seemed to love it. Alomar and Everett are two former All-Stars. Everett may be motivated to get a contract, and he has not bumped an umpire in months. Meanwhile, Alomar, reunited with his brother Sandy, may decide to come out of his coma.

Still, this is exactly the kind of panicked, overhyped, unimaginative, money-driven, fantasy-baseball move that usually blows up.

He also points out that the pick-up of Curt Leskanic for two marginal prospects may end up helping the Royals more:

[T]his is exactly the kind of subtle move that makes teams better. The Royals had to improve their bullpen. So they traded a couple of guys who didn't fit in their future, spent a little extra money and got a guy who might make a big difference in that bullpen.

It's a more logical move by a team that has defied logic by playing better when its stars are out (Beltran earlier in the year and Sweeney now). I still think that the White Sox are going to win the division, but I don't think that these two trades will be the reason for it. A reasonable second half by Paul Konerko and some reasonable offense from third (which they still need) and center should be enough.
