Watch it

NCAA Tournament (6 p.m., CBS). It’s the championship game, as Butler hopes to cap its Cinderella story. All that stands in the way? Duke.

“Chuck” (8 p.m., NBC). In what was originally supposed to be the season finale, Chuck has to save Sarah from Shaw, now that Shaw knows she killed his wife.

“Gossip Girl” (9 p.m., The CW). Jack has an indecent proposal for Blair, and Jenny tries to break up Nate and Serena, because she just hasn’t made enough bad decisions recently. Seriously, what is with that girl?

“Damages” (10 p.m., FX). Patty finds herself in a bind after the DA has Tessa arrested.

Play ball!

Wooo! It’s opening day of baseball season. About time. The Cardinals and Reds go in the first game of the day (10 a.m., ESPN). Catch the Giants at Astros (4 p.m., CSN-BA and ESPN2) then the A’s host the Mariners (7 p.m., CSN-CA).

Record it

“No Reservations” (7 p.m., Travel). It’s another special episode, with Tony talking about various cooking techniques. Mehh.

“Life Unexpected” (8 p.m., The CW). Cate, Baze and Lux (geez, who named these people?) go on the road to track down Cate’s long-lost father, who looks a lot like Peter Horton.

Skip it

“24” (8 p.m., Fox). It’s two hours tonight. Don’t do that to yourself. Even Fox is trying to get this over with as soon as possible.
