Last night was on the infield.
No way. He plunked the first guy and put the tying run on with no out. By doing that, he put the defense in a position where they made two bad plays. If he doesn't give a free pass to the first batter, Gonzalez doesn't made an error (on a ball that would have been a tough out at first anyway) trying to keep the runner out of scoring position. He then leaves one up in the strike zone to Uribe (who damn near hit it out of the park) which moves the hit batter to 3rd. That put Chipper in a position to have to make a throw home instead of 1st on a ball that also would have been a tough out at first.
Bottom line.....Wagner doesn't put yet another batter on first with no outs, that whole inning plays out differently. Gonzalez and Chipper both got an error, but only because they were put in a position where they would have had to make an incredible play to save the inning. You can blame it on the infield. I'll put it on Wagner, who picked up another blown save.
