Baggy pants? I'm a New York Yankee fan and I've only seen four active players that wear baggy pants (Thome of the Indians, Maddux of the Braves, Hernadez of the Yankees and Bartolo Colon of the Indians.) Back in the early part of last century everyone wore baggy uniforms. Some players wore baggy clothes because "it makes them look like a slugger". According to my brother it makes them look like a pile of clothes.
Also away uniforms are baggier than home uniforms.
