What to watch: easy like Sunday morning

9:30 a.m. ET, MSNBC, Men's tennis: Roger Federer starts his march to Federer/Nadal II (fingers crossed!) against Russian Dmitry Tursunov.

10:15 a.m. ET, NBC, Men's basketball: According to Nick, one billion people are going to watch this game between U.S. and China. Don't be one of the clueless four billion.

Noon, ET, CNBC, Boxing: Flyweight and lightweight matches continue. In case you're wondering, the flyweight guys weigh less than 115 lbs (52 kg), and can still knock you out.
