The Mets and Astros have recently engaged in trade talks, according to Marc Carig of The Athletic.
Houston has shown interest in right-hander Seth Lugo while the Mets have been doing "background work" on Astros minor leaguers.
It is unclear if the discussions have gained much traction but Lugo's name was floated out as part of wider-ranging talks, per Carig.
Lugo, 29, showed his versatility last season, evolving into a valuable arm out of the bullpen that can provide innings while also being someone who could be plugged into a spot start if needed.
He finished last season with a 3-4 record and 2.66 ERA (3.17 FIP) and 103 strikeouts in 101.1 innings, or a 9.1 K/9 ratio.
The Astros farm system is considered among one of the most improved in 2018, per MLB Pipeline, and contains four top 100 prospects, which includes outfielder Kyle Tucker and right-hand pitcher Forrest Whitley ranking in MLB Pipeline's top-10.
