The Pirates could make closer Tony Watson available via trade later this season, surmises Jon Heyman of FanRag Sports.
The 31-year-old Watson -- a left-hander -- has a 1.32 ERA (4.12 FIP) and 1.39 WHIP with five walks and 11 strikeouts in 13 2/3 innings (12 games) this season while converting seven of eight save opportunities.
Watson, who is making $5.6 million in 2017, is eligible for free agency after the season.
He has held left-handers to a .206/.273/.287 slashline during his career, while right-handers have hit .211/.283/.351 against him.
The Mets could soon be without closer Jeurys Familia, who has an arterial clot in his right shoulder that may require surgery.
Addison Reed filled in at closer earlier this season while Familia served his 15-game suspension stemming from the alleged domestic violence incident he was involved in during the offseason.
