Tim Wakefield is experiencing tightness in his right shoulder, the injury that knocked him out of commission for the 2007 World Series. He’s been sent back to Boston, will miss his start Tuesday and be placed on the disabled list. Bartolo Colon’s most recent rehab start was a struggle, so he may not be the solution. David Pauley is on the 40-man roster and could see action, but the Sox may give the assignment to knuckleballer Charlie Zink, who has been ramming the major league door with his shoulder all year, trying to get through. Is this his chance?
