A journeyman in baseball is typically defined by the number of teams he has played for.

It might be better to measure Michael Tonkin by the number of countries he has played in (four), searching for the type of opportunity the Mets are now giving him.

Tonkin is part of a crowded bullpen competition in Mets camp, where new president of baseball operations David Stearns has built a group that is fairly deep with possible options but fairly shallow in certainties.

Behind Edwin Diaz will be Adam Ottavino and lefties Brooks Raley and Jake Diekman. High-upside, low-floor types Drew Smith, Shintaro Fujinami and Jorge López loom as interesting projects, while multiple-inning candidates such as Tonkin, Sean Reid-Foley, Reed Garrett and José Butto (if he is converted from a starter) could be helpful for a team that will need innings eaten.
