Spring Training: Mets vs. Indians

I'm sitting here watching the Mets minor league defense let routine play after routine play go for hits/ errors, and all I hear John Kruk and Karl Ravech say is how Oliver Perez is letting it get to his head. After an error and a mis-played pop up led to 1st and 2nd, no out, Oliver Perez gave up a long fly ball to Travis Hafner which was mis-played by Angel Pagan. So the ESPN announcers mention that Pagan misplayed it, but then go on to say that Perez is not "picking his teammates up" and that his defense's bad play is getting into his head. Then Jhonny Peralta hit a single and Travis Hafner was thrown out trying to score, but the catcher dropped the ball. So by this point there should have been four outs. However, the ESPN announcers continue to explain how Perez could not "pick his teammates up" and how he was rattled by the poor defense behind him. I don't know if there is something I'm missing here, but when base runners get on due to poor defense, and then they score due to poor defense, how is that the pitchers fault? Then they showed his stat-line which said 6 runs, 6 ER. The first batter that got on, got on by way of error. Isn't that an unearned run? I guess it's spring training for ESPN as well.
