Rivera was owed $1.7MM under his arbitration contract, and Tampa Bay will remain on the hook for around a quarter of that (45 days of pay) if he’s not claimed. The club will apparently go with Curt Casali and Hank Conger behind the dish.
Rivera, 32, came to the club in the three-team swap that also brought in outfielder Steven Souza. The highly-regarded defender was coming off of a breakout 2014 season with the Padres after receiving only scattered MLB action previously. But Rivera struggled last year, putting up a meager .178/.213/.275 slash in his 319 plate appearances.
The Rangers and Astros have just filled their needs for additional veteran receivers, though surely some other organization will see fit to add Rivera in some capacity. Despite his questionable bat, he remains a useful presence behind the plate.
Carpenter, 30, was competing for a pen spot. The right-hander has had some strong campaigns in years past, but struggled with injuries last year and saw his strikeout tallies plummet. He ended with a 4.01 ERA in 24 2/3 innings, split between the Yankees and Nationals.
