The Boston Red Sox have named their Opening Day starter ... at second base. With Dustin Pedroia bound for the disabled list while he continues to recover from offseason knee surgery, Eduardo Nunez will play second base in three weeks when the season begins March 29 against the Tampa Bay Rays at Tropicana Field, manager Alex Cora announced Thursday. It had been presumed that Nunez, who plays every infield position and gave the Red Sox's offense a boost last summer, would fill in at second base until Pedroia returns, likely in late April or May. But Nunez also hadn't played in a Grapefruit League game until Thursday, a delay caused by both his own recovery from a knee injury and the fact that he didn't re-sign with the Red Sox until Feb. 18.
