Posey, Heyward among 133 who file for arbitration
Six extra players filed because of a change to baseball's labor contract: Washington reliever Drew Storen, San Diego shortstop Everth Cabrera, Toronto catcher Josh Thole, Tampa Bay outfielder Sam Fuld, Colorado outfielder Tyler Colvin and Arizona third baseman Chris Johnson.
Under the latest labor deal, the top 22 percent of players by service time with at least two years but less than three are eligible for arbitration. From 1991 through last year, the top 17 percent in the 2-to-3-year group could file.
Players and teams are scheduled to swap proposed salaries Friday, with hearings before three-arbitrator panels next month in Phoenix. Most cases settle before they go to hearings.
