The New York Mets have made right-hander Bartolo Colon available as the July 31 non-waiver trade deadline nears, industry sources told Colon, 41, has performed well in his first season with the Mets, producing an 8-8 record and 3.99 ERA in 18 starts, and may be ideal for a contender looking for a sturdy middle-of-the-rotation arm. He is making $9 million this season and $11 million in 2015 as part of the two-year deal signed on Dec. 16. Although general manager Sandy Alderson has suggested a surplus of arms can quickly be depleted through injury, the Mets do have an excess at the position. Jonathon Niese, Zack Wheeler, Dillon Gee, Jacob deGrom all remain under the Mets' control for multiple seasons. Matt Harvey is due to return from Tommy John surgery next year. And the Mets also have highly regarded prospects Noah Syndergaard and Rafael Montero in Triple-A.
