On TV tonight
MLB baseball, 1 p.m., ESPN It's opening day, so we've got the Detroit Tigers at the Yankees, then the San Diego Padres in St. Louis, then the defending champion San Francisco Giants at the L.A. Dodgers. Twelve hours should do you for the first day.
SERIES PREMIERE From the Edge With Peter Lik, 8 p.m., Weather The Aussie photog heads around the U.S. to show Americans things they'd go look at if gas wasn't $4 a gallon. Don't ask us how that's weather-related.
Grey's Anatomy, 9 p.m., ABC Sara Ramirez's pop singing career never really got off the ground, but that's okay, because they've finally done a musical episode for this series. Just what we always didn't want.
Mobbed, 9 p.m., Fox Howie Mandel helps people put together flash mobs. Don't know what that is? Don't worry, you'll know when you're caught in one.
