The players' association will monitor the Miami Marlins following their payroll purge. The union says it's too early to determine whether the salary cuts will cause any issues under baseball's labor contract.

Baseball's labor contract requires that revenue-sharing money be used in to improve a team's performance on the field.

The Marlins opened last season with a $112 million payroll and cut it to $90 million by the end of the season. With the trade of All-Star shortstop Jose Reyes and four others to Toronto on Tuesday, Miami's payroll next season is projected at about $36 million.

Commissioner Bud Selig approved the deal Monday. Union head Michael Weiner said Tuesday he is not surprised by Selig's decision, but "we'll be monitoring the Marlins for compliance" with baseball's labor agreement.
