When San Francisco Giants rookie Mike Yastrzemski takes his place in the outfield at Fenway Park in Boston this week, the shadow cast above him will be long. Yastrzemski, the grandson of Hall of Famer and Red Sox legend Carl Yastrzemski, makes his first trip to his grandfather's old stomping grounds as the Giants visit the Red Sox for a three-game series beginning Tuesday. Right-hander Logan Webb (1-2, 6.75 ERA) will get the start for San Francisco in the opener of the interleague set.
