What to watch as Selig orders a probe of your fantasy team ... • Boxing: Super welterweights, Anthony Thompson vs. Darnell Boone ; super lightweights, Victor Ortiz vs. Freddy Barrera, at Maywood, Calif. This had better not pre-empt Weeds. [ Showtime] • Major League Baseball: Preseason, Chicago Cubs vs. San Diego, at Las Vegas. What happens in Vegas, stays in Vegas ... except for major league sports. [ WGN] • NBA: Memphis vs. New Orleans, at Oklahoma City; Los Angeles Lakers at Seattle. The NBA and Oklahoma just go together, don't they? [ ESPN]
