Jon Heyman of Sports Illustrated says the Florida Marlins have turned their managerial search attention to Bo Porter, current third base coach of the Arizona Diamondbacks.

Porter, 37, was in Miami on Friday to interview with the management team. He was the Marlins’ third base coach and outfield instructor from 2007-2009.

It was believed that Bobby Valentine was all but officially selected as the next manager of the Marlins, but the situation “blew up” over the weekend.

FOXSports says there may be an internal conflict with owner Jeffrey Loria and club president David Samon over Valentine.
