The White Sox got home runs from Dayan Viciedo, A.J. Pierzynski and Adam Dunn in their 7-4 victory over the Cubs Saturday at Wrigley Field. With the win, the Sox have now taken the first two games of the annual crosstown series.

If you've followed the goings-on between these two teams recently, this should be no surprise. The Sox are 47-39 all-time against the Cubs and have dominated the City Series over the last four years. The South Siders are 17-6 in the last 23 meetings between the two clubs since June of 2008.

Thing is, the Sox really have trouble finishing off sweeps of the Cubs for some reason. This weekend's meeting marks the 13th time in the history of the rivalry the Sox have taken the first two games of a three-game series. On the previous 12 occasions, the Cubs have salvaged the final game 10 times. Despite their overall lead in the series and general recent dominance, the Sox have only swept a crosstown series twice (1999 at Wrigley, 2008 at U.S. Cellular Field).

If there was ever a time for the Sox to finish off the Cubs, I'd say this would be it. Sure, the Sox are every bit as mediocre as their 20-21 record suggests. However, this is probably the worst Cubs team I've seen since 2006. The North Siders have a record of 15-25, and frankly, it's a miracle they've won 15.

Probably the only thing the Cubs have going for them Sunday is the presence of a left-handed pitcher on the mound. The Sox are only 4-7 against left-handed starters this year. They typically struggle even against mediocre dreck like Paul Maholm, the Cubs' scheduled starter in the series finale.

Can the Cubs scratch out one win and salvage some pride? Or will the White Sox finally show some killer instinct?
