Rodrigues' afternoon drive seat was filled by then-production director "Fast" Eddie Garcia and sports-talk personality "The Hurricane" Mike Herren.

Phelan left the station in the spring of 2010 after accepting a position with Bristol Eighth District Mike Rodrigues' State Senate campaign to replace the retiring Joan Menard.

In summer 2012, Giammarco returned to WSAR, this time as general manager and program director, the first PD since Rodrigues, who had moved on to be a union organizer with the SEIU in Boston.

Long-time on-air host and newspaper journalist, Ric Oliveira, left his post at Gatehouse Media where he was publisher of O Jornal and became general manager on April 1, 2013.
