PLAY BALL: Scorecards ready? It’s time for the fourth annual T.J. Martell All-Star Celebrity Softball Games, which unfolds next Sunday with a cast of free-swinging rock sluggers. After several games, including a grudge match featuring a Mark & Brian-led KLOS-FM team against KNAC-FM’s finest, the finale will feature a battle between the Rockers, led by Kip Winger, vs. the Rollers, led by Warrant lead singer Jani Lane. Participants will also include Poison’s Brett Michaels, Neil Geraldo, Whitesnake’s Rudy Sarzo, Brian Setzer, Ratt’s Bobby Blotzer, Steve Jones, Fee Waybill and Bon Jovi’s Alec Johnsuch. Tickets are $12, with all proceeds going to the T.J. Martell Foundation, a popular music industry charity devoted to cancer, leukemia and AIDS research. . . . And this Tuesday at the Palomino Club, Ronnie Mack’s Barn Dance will host a special birthday tribute to the late Ricky Nelson (it would’ve been his 50th ). The free-admission show begins at 8:30 p.m. and will feature such artists as Rosie Flores, the Lonesome Strangers, Candye Kane and Ray Campi (all performing Nelson songs).
