Money being spent on draft has Pittsburgh following rules

John Perrotto mentioned on twitter today that MLBPA looked into whether the Pittsburgh Pirates had violated revenue-sharing rules like the Florida Marlins.
The Marlins are being investigated for violations but John tells me what has Pittsburgh not being targeted is the amount of money they have spent on the draft in 2008, 2009 and the fact that they built the Dominican academy.
That has been enough to satisfy the MLBPA, despite the Pirates having one of the lowest payrolls in the league and not putting too much money into their on the field product.
The Pirates are projected to have a payroll in the $35 million range for the 2010 season.
