I was going to write a longer preview for this series, but I saw the Cubs probable pitchers and gave up.
Friday: Rodrigo Lopez
Saturday: TBA
Sunday: Ramon Ortiz
Saturday will probably end up being Dempster as he threw a bullpen session yesterday and was reportedly feeling good. Though I guess it's possible he could produce a human infant in the next few days and get scratched, given how wierdly his injury was described.
The Cubs did an admirable job losing to the Nationals though they managed to screw up yesterday's game. At this point I'm confident that they'll be swept by the Pirates this weekend.
