Outside of deGrom, the Mets have only one reliable starter - Noah Syndergaard -- and even Thor can be erratic at times. While Syndergaard has walked only five this year, he has given up 13 runs in 24 innings, and is susceptible to getting hit. Zach Wheeler and Steven Matz are too up and down for Mets fans to know what to expect from either one of them on a regular basis. Jason Vargas ... I won't even go there. As a whole the Mets have a team ERA of 5.54, ranked 27th in Major League Baseball. They are also 29th in the league in OBP with teams hitting .273 against them. The team's WHIP registers at 1.53, tied with Baltimore for dead last. 
Were it not for a Mets offense that has been hitting extremely well, even with Robinson Cano mired in a slump, and the solid efforts of Edwin Diaz at the back-end of the bullpen, who knows where the Mets would be right now. They need their pitching staff to stand up and deliver. 
If deGrom is to miss any time, the Mets need to get serious about getting help, and I am not talking about recalling Corey Oswalt. If the Mets think they have a shot at the Phillies, they need to give free agent starter Dallas Keuchel serious consideration.
