Adam Rubin is pointing out that the Mets are facing a 40-man roster crunch. Eight players have to be moved from the 60-day disabled list soon: Ike Davis, Josh Edgin, Matt Harvey, Jeremy Hefner, Jenrry Mejia, Bobby Parnell, Scott Rice and Johan Santana. The team also has only eight free agents: David Aardsma, Tim Byrdak, Pedro Feliciano, Frank Francisco, Aaron Harang, LaTroy Hawkins, Daisuke Matsuzaka and Santana. In addition, the team has several players that they have to add to the 40-man roster or be lost in the Rule 5 draft: Jacob deGrom, Steven Matz, Darin Gorski, Jeff Walters and Cory Vaughn among others. Rubin lists Jordany Valdespin, Scott Atchison, Greg Burke, Robert Carson, Sean Henn, Zach Lutz, Mike Baxter, Andrew Brown and Kirk Nieuwenhuis as the ones most likely to go. So . . . who should stay and who should go? Who won't be on the 40-man roster by the time of the Rule 5 draft in December?
