According to a spokeswoman for Pawtucket Mayor Don Grebien, House Speaker Nicholas Mattiello is going to meet in the coming weeks with Pawtucket Red Sox officials to discuss the stalemate over a proposed stadium.  Mattiello has raised concerns about using taxpayer money to help finance the 83-million-dollar project.  A bill has passed the Senate, but has stalled in the House.  Without a new ballpark, PawSox officials have threatened to move the team out of Rhode Island.
