The Mets' search for bullpen help has led them to some prominent free agent relievers. The Mets are pursuing Jose Valverde, and would even consider bringing Francisco Rodriguez back to New York, Adam Rubin of ESPNNewYork.com reports. However, a deal with Brian Wilson is now considered “very unlikely.”

The Mets are interested in signing Valverde, but only on their terms. Rubin suggests the Mets might be prepared to guarantee Valverde $4MM on a deal with significant incentives. Though the Mets have some interest in Rodriguez, he is believed to be seeking about $7MM, according to Rubin. Both free agent right-handers are clients of the Boras Corporation.

The Mets visited Roy Oswalt to convince him to join the team as its closer, Rubin reports. Oswalt is not interested in becoming a closer, so he’s no longer an option for GM Sandy Alderson. The Mets have one serious offer out to a late-inning reliever who’s not a closer, Rubin adds. The team expects to hear back from the player shortly.

If the Mets don’t add any relievers, Frank Francisco would likely be the club’s closer. Follow @closernews on Twitter throughout the season for closer-related news and analysis.
