Play ball! It's another sign of spring -- the opening games of the baseball season. Officially, Major League Baseball began its season this week with a series between Boston and Oakland played in Japan, though purists will argue that the real Opening Day won't take place till the first regular-season games on U.S. soil next week. In this segment, we'll talk about science and medicine as they relate to America's pastime, from statistics to orthopedics and psychology.
