Yamming It Up.

The author talks about the routine of Jason Giambi, a first baseman/designated hitter for the Oakland Athletics baseball team, of eating yams before a game. He reports that the athlete is so into energy food that he insists on a certain variety, Beauregard, which has a darker color and higher natural sugar than most varieties. According to Giambi, he got the idea of eating yams from hitter Alex Rodriguez, whom he saw eating them when they were both with the New York Yankees. The author believes that demand for yams will rise in Northern California.
