Nate Schierholtz's recent power surge might not be enough to turn the Chicago Cubs season around. It sure is making the year a lot easier for the slugging outfielder to handle. Getting a game-winning home run against his former club? Well, that's just icing on the cake. Cheered in every at-bat this series by the crowd at AT&T Park, Schierholtz homered off ex-teammate Sergio Romo with one out in the ninth inning to lift the Cubs to a 1-0 win over the San Francisco Giants on Saturday night.
