* MLB Baseball (12:30 pm/ET MLB)
Sound the trumpets, release the doves, and be in awe as the new Yankee Stadium opens its doors for the Bronx Bombers' long-awaited home opener. Alongside analysts Jim Kaat and Harold Reynolds, MLB Network reintroduces none other than 19-time Emmy winner Bob Costas for his first play-by-play since the 2000 ALCS, played across the street in what was The House That Ruth Built. That was the last World Championship season for the Yanks, so maybe Costas is the cosmic influence Joe Girardi's bunch needs to find October happiness. The Blue Jays and Twins play in the network's regular Thursday Night Baseball game.
* CSI: Crime Scene Investigation (9 pm/ET CBS)
It's not a crossover episode but Battlestar Galactica fans should enjoy this quirky hour, which gives a generous nod to the sci-fi series. BSG's Kate Vernon guest stars, and it's directed by Galactica helmer Michael Nankin and written by former Battlestar scribes David Weddle and Bradley Thompson. The action takes place at a sci-fi convention, where a producer is murdered. Fortunately, Hodges and Wendy are at the showcase and investigate, which allows the underused Wallace Langham and Liz Vassey to shine in numerous fantasy sequences.
* Bones (8 pm/ET Fox)
Nowadays Booth and Brennan may be lying on Sweets' psychiatric couch, so to speak, but tonight they get a visit from their old therapist, Dr. Gordon Wyatt (Stephen Fry). Wyatt, whom we haven't seen since 2007, helps Sweets with a book he's writing on our intrepid crime solvers, and he also pitches in when the team investigates a gruesome discovery in the death-metal music scene.
* American Chopper (9 pm/ET TLC)
Teutul family conflict has always been the norm at Orange County Choppers, but the blowup between Sr. and Jr. in last week's Season 6 opener took things to a whole other level. Tensions between the father and son continue to escalate tonight, and the shop's entire foundations are seriously shaken. On a lighter note, the rest of the crew clowns around while building a motorcycle inspired by the circus. And a Woodstock-themed bike is built in celebration of the legendary music festival's 40th anniversary.
* 30 Rock (9:31 pm/ET NBC)
Liz Lemon is sometimes tart - yet always palatable - but she's turning slightly sour tonight. The squeeze is on Lemon when she's saddled with a suspension from work. A lost soul without all the TGS chaos and rolling Rock rowdyism, Liz seeks a way to bide her time. Meanwhile, there's some reel-world anxiety when film bigwigs mull over pulling the plug on Jenna's Janis Joplin movie. In a desperate response, Jack and Jenna try (just a little bit harder) to stir up buzzworthy publicity.
