In the second contest of a doubleheader last night, Washington Nationals rookie hurler Joan Adon threw an incredible game, and earned the first win of his career. Adon, who threw six-and-one-third scoreless innings, wowed fans by fanning five Arizona Diamondbacks batters. Adon, who is just 23 years old, showed incredible poise and confidence in the first win of his Major League Baseball career.
