According to the New York Times, the Mets are interested in Tomo Ohka or Tony Armas Jr. to fill in the middle of their rotation. Both pitchers played under Minaya when he was GM of the Expos. Ohka would likely require a two-year deal, while Armas might be had for one year and $5MM or so.
Meanwhile, the New York Post adds that the Mets could give Jeff Weaver a second chance in New York. They’d be unlikely to exceed a two-year deal, and I have a hunch someone could offer three. Once again, Scott Boras and Weaver are signing a contract late in the free agent season.
