NEW YORK (WFAN) – A trio of Mets relievers are reportedly on the trading block.

According to the New York Daily News, Mets general manager Sandy Alderson is “aggressively” shopping closer Francisco Rodriguez, setup man Jason Isringhausen and lefty reliever Tim Byrdak.

Alderson is hoping for “decent minor leaguers” in return, reported the paper, but may have to settle for a mere salary dump as the July 31 trading deadline approaches. The cash-strapped club will need all the payroll they can muster for a possible run at re-signing Jose Reyes.

Rodriguez’s contract could be a major obstacle toward retaining the star shortstop.

If K-Rod finishes 55 games with the Mets this season, he’ll trigger a $17.5 million option for 2012. If he doesn’t, his contract can be bought out for $3.5 million.

Rodriguez is on track to trigger the hefty price tag with 32 finishes on the year so far.

In May, K-Rod said he would be willing to waive his no-trade clause for new multi-year extension. Last month, Rodriguez told the Daily News he’d even be happy to serve in a setup role for a team in playoff contention — like the Yankees.

“If I am going to be traded, obviously I want the opportunity to close out games,” K-Rod, who has 10 undisclosed teams listed in his no-trade clause, told the paper, “but if it’s going to be good teams like the Yankees or the Rays, and it’s going to be for two months, I can go out there and help them out.”
