Hate to say "team of destiny" or whatever but despite the Mets bullpen giving up late leads in three of their four losses, I don't think you can run out and say "The Mets need to bring in an A-list closer at whatever the price to get over the hump" or anything like that.
The Royals just had their bats on fire in the clutch. Yeah, Murphy had a costly error the other day but they piled on 2 more runs after that.
Sometimes you just run into the team that is supposed to win and that happened here. Better luck next year... Mets have enough starting pitching to keep winning the division for a few years at least.
