That's impressive. Not high-percentage baseball, but a testament to their perseverance and the weakness of the Mets bullpen. And also, that the Royals pounced on any opportunity the Mets provided via poor defense - see Murphy's error in Game 4 or last night's ninth inning.
Also, Murphy cost the Mets a game, I forget which, when he didn’t make an error, just didn’t throw to the cutoff man. Allowed the go ahead run to score from second, and that was the final score for a loss.
The Mets road good starting pitching and powerful, if streaky, hitting to the World Series. That can hide lack of bullpen and lack of defense only so far. But what the Mets really lacked was heart. They couldn't battle back from adversity. They didn't have faith in themselves as a team.
