They were more concerned about Fukudome on base than the batter. No chance to steal. Bunt for what, so Lieber could drive him in? Lieber batted because the Cubs are out of extra players.
Technically, only one of the errors really affected the score. Both Cedeno's and Ramirez's throws were on IF singles, so if anything they both just made the runs score faster. Lilly was awful, though, especially with the walks, given a 7-run lead.
