With the process underway, the Marlins will look to finalize deals with the three before Friday's deadline to exchange salary figures. If no deal is reached by the deadline, each side will present a figure, and the salary will be determined by an arbitration panel. The salary arbitration hearings will run from Feb. 1-21.
Technically, the sides can keep negotiating up until the arbitration hearing is set to begin. But the Marlins have had a standing policy of shutting down talks once figures are exchanged.
Stanton, who has 117 home runs since breaking in as a rookie in 2010, will earn a significant increase over the $537,000 he earned last season. The Marlins have stated publicly they are willing to talk a multiyear deal with Stanton. The next few days will give a better indication if that indeed is the case.
Cishek, who made $505,000 last year, converted 34 of 36 save chances in his first full season as closer. He has converted 52 of 58 career save chances.
Dunn, a left-handed setup reliever, has been a durable and effective performer since joining the Marlins in 2011. Last year, he posted a 2.66 ERA in 75 appearances. The 28-year-old made $492,500 in '13.
