I think overall this is an apples and oranges comparison. That CWS team indeed had more pressure to produce. But this was a team that was had overcome their drought already and was very confident. They were bonded as a team by that point. So the pressure, although more intense, did not effect them as much. Just my opinion.
I don't know if our guys had as much pressure Friday night as they did Saturday afternoon and then even more on Sunday afternoon. Those slumps can build in a way that screws with you mentally.
Friday, they were swinging at stuff they probably wouldn't normally swing at (fastballs way up in the zone) showing me that they were pressing. Trying too hard to get the big hit on the big night. Which is not good against a Friday night arm. They were letting the pitcher dictate the action instead of hunting.
