Mets minor leaguers Anthony Gose and Jon Singleton each triggered upward mobility clauses in their contracts, reports Anthony DiComo of MLB.com. That requires New York to offer them to other teams. If another club is willing to give either player a big league roster spot, the Mets would need to call them up themselves or let them head elsewhere (likely in a trade for cash).

Gose signed a minor league deal last December and was with the Mets in Spring Training. He worked six innings of one-run ball in camp. Gose has pitched 15 times for Triple-A Syracuse, pitching to a solid 3.31 earned run average over 16 1/3 frames. He has fanned a quarter of opponents but is walking more than 15% of batters faced. That’s par for the course for Gose, a former outfielder with a mid-90s fastball and scattershot command.

The Mets are stretched on left-handed relief depth after the A.J. Minter and Danny Young injuries. They called up minor league signee Génesis Cabrera to work as Carlos Mendoza’s primary southpaw. They added a second lefty last night, acquiring José Castillo in a DFA trade with the Diamondbacks. Gose has a relatively clear path to the big leagues in Queens, though they’ve already added two other depth arms to their bullpen instead of promoting him.

Singleton, a lefty-hitting first baseman, was in camp with the Astros. Houston released him at the end of Spring Training. He signed a minor league deal with New York at the beginning of April. He has appeared in 33 Triple-A games, batting .216/.358/.432 with seven home runs.

He’s hitting for power and drawing plenty of walks, but he has fanned in nearly 30% of his plate appearances. Singleton had a career-high 405 trips to the plate with Houston last year, batting .234/.321/.386 with 13 homers. With Brett Baty hitting well since being recalled two weeks ago, the Mets probably wouldn’t have room for Singleton if another team were willing to call him up.
