The St. Louis Cardinals made their first move toward upgrading their offense on Tuesday, trading right-hander Blake Hawksworth to the Los Angeles Dodgers for shortstop Ryan Theriot.

Theriot became expendable earlier this week when Los Angeles signed Juan Uribe, who can play multiple infield positions like Theriot, but has a little more pop.

Today, Andy Pettitte will pitch a bullpen session in Chicago. There are two possible outcomes for this situation.

Good outcome: Pettitte could return in mid-September and be the horse he was before the injury, when was on his way to a Cy Young-type season. 

Bad outcome: He could feel a "pull" in his groin, and the Yankees could be stuck with the pitchers they have, or get someone off waivers.

As reported by Bob Elliott of the Toronto Sun, the Blue Jays put both Vernon Wells and Edwin Encarnacion on waivers earlier in the week. News has come out that both of them have cleared waivers and can now be traded.

Wells comes as no surprise, given his monster contract, but Encarnacion clearing does raise questions on his future with the ball club.
