Robert Gsellman could be on borrowed time in this rotation, but these are the Mets, for whom even the best-considered plans change often, so don’t bet on anything.
This much is known: Gsellman has shown improvement over his last two starts, after a dreadful stretch to begin the season, and the Mets plan to insert Steven Matz and Seth Lugo into the rotation after each makes at least one additional rehab start.
For Gsellman that would mean a shift to the bullpen as soon as early next week, after starting against the Pirates on Saturday.
