Yes. The Mets are in the middle of a slide in which they have lost 13 of 16 and surrendered a 5.5 game division lead to the Phillies, who haven't exactly been tearing things up themselves. I'm sure their fans are very laid back about it.
While the Mets did get swept by the Pirates and are now 2-4 against them for the season, they are also 8-1 against the Rockies and White Sox.
The real sticking point for me is the historically bad Rockies, who will have a home and home series against every NL team, and 4 series against the 4 playoff contenders in the NL West. Games against the Rockies should be seen as a golden opportunity to stack up wins. The Brewers did not take maximum advantage of that opportunity the way most of the other contenders have and therefore dropped a couple of games in the standings that might have to be made up somewhere else.
The record of the 10 NL playoff contenders against the Rockies so far is a combined 43-7. The Dodgers, Cubs, Phillies, Mets, and Reds are a combined 25-0, and the Cardinals haven't faced them yet.
