The Mets are looking for a “placeholder” starter and a big prospect as well, according to Joel Sherman of the NY Post. The Yankee have a number of pitchers who could serve as a “placeholder” but they would probably prefer to use Hector Noesi, David Phelps, or Adam Warren as a centerpiece in a deal for a non-elite starter.
The Mets and the Yankees don’t often trade with each other. It seems unlikely that they would make a deal here, but it’s certainly worth exploring.
Niese, 25, has a career ERA of 4.39, a K/9 of 7.65, a BB/9 of 2.99, and a GB% of 49.1. Those are solid peripherals despite a less than spectacular ERA. There should be concerns of how well he would do with a switch to the AL, but he is young enough and left handed. If the package isn’t extreme he is probably worth going after.
