Lugo (elbow) will make one more rehab start and then join the Mets as a member of the starting rotation.

General manager Sandy Alderson made this announcement Monday, but that came before Robert Gsellman -- who's expected to be moved to the bullpen when Lugo and Steven Matz rejoin the team -- went out and delivered his second straight solid start. Lugo allowed three runs on eight hits and two walks with seven strikeouts during his six-inning start for Double-A Binghamton on Sunday. He tossed 79 pitches in the outing, and the plan is to get him close to 90 in another Double-A outing before he rejoins the big club.
