On tap: The 2013 Major League Baseball season begins with an 8 p.m. ET broadcast of ESPN's "Sunday Night Baseball" on March 31, as the Texas Rangers, winners of 279 games the past three seasons combined, host the Houston Astros in the latter's American League debut. From there, we get baseball's traditional "Opening Day" on Monday, April 1, and ESPN's quadruple-header beginning with a Boston Red Sox at New York Yankees contest (1 p.m. ET) and including the defending World Series champion San Francisco Giants' opener at the Los Angeles Dodgers (4 p.m. ET), the Philadelphia Phillies at the Atlanta Braves (7 p.m. ET) and the St. Louis Cardinals at the Arizona Diamondbacks (10 p.m. ET).
