The White Sox gave the Cubs a taste of their own medicine and pulled off an impressive 3 game sweep of their Chicago counterparts this weekend, complete with stellar starting pitching, power throughout the lineup, and a lights out bullpen. Like the Sox the previous weekend, the Cubs simply could not get anything going all weekend. It appears that injuries, as well as tougher competition courtesy of the American League, has driven the Cubs to their first mini-slump of the season entering a 4 game series in San Francisco. The only good news from this weekend may be the improving health of stars Alfonso Soriano and Carlos Zambrano. Soriano is apparently healing very well and may return sooner than expected. Zambrano completed a bullpen session this evening and is slated to start next friday versus division rival St. Louis. All in all, this weekend series between two first place teams supported the statistical evidence that showed that regardless of the personnel or the year, these teams will always be very evenly matched.
