Mets right-hander Seth Lugo appeared in his second rehab start on Sunday as he works his way back from a partially torn UCL.

Lugo, 27, toed the rubber for Double-A Binghamton against the Hartford Yard Goats and fired six innings, allowing three runs on eight hits, while punching out seven and walking two.

All three runs for the Yard Goats came in the third inning after Lugo loaded the bases to begin the frame, then proceeded to surrender a single, walk in a run and push the third across with a suicide squeeze.

However, Lugo finished off his outing strong, keeping Hartford at bay the next two innings.

In Lugo’s first outing with Single-A St. Lucie on May 18, the righty tossed 3 2/3 scoreless innings.
