Neither Orlando Hernandez nor Mike Pelfrey, thought to be the lone candidates for the fifth slot in the Mets' rotation, has distinguished himself; together they have created an opportunity for Sosa. A person in the Mets hierarchy indicated Tuesday that the club is considering Sosa for the seemingly unclaimed No. 5 assignment, noting that the recently improved relief work of Joe Smith and the swing-and-miss pitches of Brian Stokes have the Mets thinking they can afford to remove Sosa from the bullpen alignment. source MLB.com
Of course many believe that Omar will look outside of the the organization to fill the spot and is simply waiting to see who's placed on waivers. Now let me make this clear; I'm not suggesting this guy, I'm simply reporting on him because he's being discussed and offering my opinion. Claudio Vargas has been released by the Brewers and Joel Sherman of the NY Post discusses him as a possibility for the Mets. If Omar believes the team needs a long term solution for the fifth spot, then they'll have to bring someone in and if they believe Vargas is the best option based on availability and cost then he makes sense.
Don’t be surprised if the Mets try to sign Claudio Vargas, who was released by the Brewers. Omar Minaya has history with Vargas. In one of his first major moves as a GM – with the Montreal Expos in July 2002 – he traded, among others, Carl Pavano to the Marlins for a package that included Cliff Floyd and Vargas. Vargas served as a swingman with the Expos in 2003-04, and the Mets could conceivably use the same entity now with Orlando Hernandez and Mike Pelfrey struggling to grab the No. 5 spot in the rotation and limited organizational rotation depth behind them. source NY Post
