Kentucky Derby

Kentucky Derby
4 pm/ET NBC
"The most exciting two minutes in sports" begin at 6:04 pm/ET in Louisville, preceded by two hours of anticipation (or anxiety, depending on how much moolah you've got invested in the race). While sipping that mint julep, enjoy one part red-carpet interviews with the rich and famous at Churchill Downs, and two parts race buildup, focusing on profiles and analysis of the expected 20-horse field. Likely post-time favorite I Want Revenge has the services of teenager Joe Talamo, a likable star of Animal Planet's reality series, Jockeys. Among the trainers, three-time winner Bob Baffert is squarely back in the Derby spotlight with Pioneerof the Nile, while Todd Pletcher has three more chances (Dunkirk, Advice, Join in the Dance) to end his personal Derby hex. For those who remember ill-fated 2008 Derby runner-up Eight Belles, her trainer, Larry Jones, is taking another shot at the Roses with Louisiana Derby champion Friesan Fire. —Roger Leister

JONAS
8 pm/ET Disney
The ubiquitous Jonas Brothers star in this critic-proof comedy as — what else? — pop superstars who are heartthrobs for millions of teen and preteen girls. But here, Nick, Joe and Kevin Lucas (the band is named JONAS) are "normal" high schoolers by day, trying to live quiet lives away from the stage. Of course, their stardom and adoring fans keep interrupting. In the opener, Nick falls hard for a pretty new student and even writes a love song for her. Joe and Kevin know he's headed for heartbreak, but lovestruck Nick refuses to see it. —Tim Holland

Living Out Loud
9 pm/ET Hallmark
Gail O'Grady stars in tonight's original movie as high-school music teacher Emily, whose cancer diagnosis causes her to re-evaluate her humdrum routine. Drawing inspiration from a spunky patient (played by Babs Chula) she befriends during chemo treatments, Emily reconnects with her passion for singing and writing music, a dream she put on the back burner while raising her kids. Her family, meanwhile, is left to adjust to Emily's shifting priorities and must find new ways to connect to each other and follow their own dreams. —Brie Hearn

The Best of Diners, Drive-Ins and Dives
8 pm/ET Food Network
Over the past few years, Guy Fieri has visited hundreds of the country's best "greasy spoon" joints, indulging in a diet that would make a nutritionist shudder. Tonight the spiky-haired host is taking a look back at his favorite moments from the series' first six seasons and the most memorable dishes he tried that were truly "off the hook." —Karen Andzejewicz

NASCAR Racing
7 pm/ET FOX
Nothing beats the look of nighttime racing, which is the only time for Sprint Cup action on the intimate three-quarter-mile oval at Richmond International Raceway. NASCAR is still abuzz over last week's spectacular crash-and-pass that sent Brad Keselowski to victory and Carl Edwards into the catch fence at Talladega. Richmond had a similar finish in this race last year, with a low-profile winner (Clint Bowyer) squeezing past a late-race wreck (involving Kyle Busch and Dale Earnhardt Jr.). —Roger Leister
