When the baseball gods are present at Fenway Park, that’s usually good news for the home team, but a pregame visitor to the Giants’ clubhouse on Thursday morning handed the visiting club some much needed mojo as they pulled off a 3-1 victory and avoided a sweep.

Prior to the game, Mike Yastrzemski was visited by his Hall of Fame grandfather Carl, one of the greatest Red Sox players of all time. The Giants’ right fielder was able to spend about 10 minutes with the man he calls “Papa Yaz” and though they didn’t talk baseball, some magic rubbed off somewhere in the mix.

“I think he left the car running when he came in here,” joked Mike of his grandfather’s brief visit to the ballpark. “That’s normal. He’s quick to the point. We didn’t even really talk about hitting. He just asked how I was feeling physically. Good to see him and it was fun to have him around for a minute.”
