Hard to say.
In a 60 game season last year, Tampa got saves from 12 different pitchers, including 5 who had multiple saves.
So were they being situational here? I didn't watch all of their regular season games (Did anyone on Earth do that who was not a Ray or married to one?)
It is hard to say because the rules for a save are rather lax and sometimes just mean pitching the last 3 innings of a game regardless of the score. For example, one of the pitchers with one save was Anthony Banda, who got his against Boston in a 17-8 game.
But then Chaz Roe had only one save, and it was in a 6-3 game against the Yankees. Situational? Andrew Kittredge also had one save, and it was in an 8-7 game against Boston...
