San Francisco Giants will hold Irish Heritage Night on June 12th before that night's game against the Houston Astros. Package includes a pregame celebration, with cultural food and drink specials, Irish entertainment, and a special edition Rory McIlroy bobblehead. Because when you think of the Giants, you think of golfer Rory McIlroy. Wait, what?
Based on the picture, it's actually a nice looking bobblehead, with McIlroy wearing a Giants baseball cap and golf shirt. The Giants are taking advantage of the fact that the 2012 U.S. Open golf tournament will be held at Olympic Club in San Francisco during that same week, so there's your golf connection.
