Brad Ausmus is getting up there in years and can only be considered a backup catcher at this point in his career, but by the looks of things his list of suitors hasn't been deterred by this. Teams reportedly interested in Ausmus include the Dodgers, Giants, and Padres. So pretty much the entire NL West. The Nationals are also said to be looking at him.
The Padres are an intriguing possibility, as Ausmus and Aaron Poreda would form a Jewish battery. And if the Nationals wind up with Marquis, Ausmus and Marquis would form a Jewish battery should they also sign Ausmus. Just another wrinkle that makes this offseason interesting.
To my knowledge, 36-year old journeyman Scott Schoeneweis isn't in high demand. But over the course of his career, he's held lefties to a .606 OPS. Schoeneweis is the epitome of a lefty specialist, and every bullpen needs one of those.
