It was announced that six members of the Arizona Diamondbacks filed for salary arbitration on Tuesday. These six players along with the club have to exchange salary proposals for the 2013 season by Friday. The list is comprised of starting pitcher Ian Kennedy, relievers Tony Sipp, Brad Ziegler, shortstop Cliff Pennington, third baseman Chris Johnson and outfielder Gerardo Parra. Ziegler and the D'backs avoided a hearing last season by settling on a $1.795 million contract. This is the first time the other five players have gone through the arbitration process which, if gone to an actual trial, can leave both sides with bitter feelings toward one another.
