The Mets just completed a nine-game stretch against the D-backs and Padres, during which they went 3-6.
They took two of three from San Diego. However, in their six games against the D-backs, who are the second-worst team in the NL, the Mets were 1-5 and let up 7.5 runs per game, while scoring just 3.8. New York's bullpen had a 10.32 ERA in the six games against Arizona.
Yes, the Mets have several injured players - they started six guys Wednesday that were not with the team Opening Day - but they still have a better pitching staff than the D-backs.
