American League MVP Josh Donaldson of the Toronto Blue Jays and Cy Young Award winners Jake Arrieta of the Chicago Cubs and Dallas Keuchel of the Houston Astros were among 156 players who filed for salary arbitration Tuesday and are set to swap proposed figures with their teams this week unless they agree to contracts.
New Yankees closer Aroldis Chapman could file the highest salary request after earning $8,075,000 US last season with Cincinnati unless he settles with New York before Friday's exchange of figures.
Donaldson lost his case last year and made $4.3 million while leading the Blue Jays to their first playoff appearance since 1993.
Other Blue Jays to file for arbitration included: Pitchers Brett Cecil, Jesse Chavez, Steve Delabar, Drew Hutchison, Aaron Loup, and Drew Storen along with outfielder Michael Saunders.
New York Mets ace Matt Harvey was among nine players from the National League champions who filed for arbitration. That group includes suspended reliever Jenrry Mejia, who failed two drug tests last year and will miss much of next season as part of a 162-game ban.
Lorenzo Cain and Mike Moustakas were among seven players from the World Series champion Kansas City Royals who filed.
Keuchel could be in for a big raise after earning slightly more than the major league minimum of $507,500 last season, when he went 20-8 with a 2.48 earned-run average. Arrieta earned $3.63 million and pitched a no-hitter among his 22 wins.
Top closers Trevor Rosenthal, Mark Melancon, Zach Britton, Kenley Jansen, Jeurys Familia and Drew Storen all put in their arbitration paperwork.
Others filing for arbitration included Jose Fernandez, Stephen Strasburg, Manny Machado, Nolan Arenado, J.D. Martinez and Anthony Rendon.
Hearings will be scheduled for the first three weeks in February before three-person panels in Phoenix.
Teams went 8-6 last year, giving them a 301-221 record since arbitration began in 1974. There were just three hearings in 2014 and none in 2013.
