Jason Heyward could get at least a six-fold increase in his first year of arbitration eligibility, and Braves teammate Kris Medlen also figures to receive a similarly major bump in salary in his first time up for arbitration. Heyward and Medlen are among six Braves eligible for arbitration, along with versatile veteran Martin Prado and relievers Eric O'Flaherty, Jonny Venters and Christian Martinez. They were part of the group of 133 major leaguers who filed for arbitration this week, and on Friday teams will swap salary-arbitration figures with those players unless deals are worked out before then. Teams can continue negotiating with players up until their scheduled arbitration hearings in February, at which point a panel would decide to award either the salary proposed by the player or the one proposed by the team. The Braves almost always settle at a point between the salaries proposed by the two sides before any case goes to arbitration.
