New York — A half-hour after getting past Venus Williams in a three-set tussle at the U.S. Open, Kim Clijsters had her hands full again.

Juggling an energy drink, a bottle of water and a snack, Clijsters was trying to keep an eye on her 18-month-old daughter, Jada, as the tyke scurried around the players’ lounge.

Better keep the nanny on call: Mommy’s got more work to do at Flushing Meadows.

Playing by far her biggest match since coming back after 21/2 years away from tennis, Clijsters knocked off the No. 3-seeded Williams, 6-0, 0-6, 6-4, Sunday in a match of wild momentum swings to reach the U.S. Open quarterfinals.

“It’s still kind of hard to believe. But then again, I’m not trying to get carried away with it all,” the 26-year-old Belgian said. “Just trying to focus on what I have to do, because the tournament’s still going.”

Against Williams, a seven-time major champion, Clijsters displayed the same sort of booming groundstrokes and all-over-the-place court coverage that helped her win the 2005 U.S. Open and briefly reach No. 1 in the rankings before leaving the tour.

Only two mothers have won a Grand Slam singles title; the last was Evonne Goolagong Cawley at Wimbledon in 1980.

Merriman arrested

San Diego — San Diego Chargers star outside linebacker Shawne Merriman was arrested Sunday and accused of choking and restraining his girlfriend, reality TV star Tila Tequila, as she tried to leave his suburban home.

Tequila, 27, signed a citizen’s arrest warrant, charging Merriman with battery and false imprisonment, San Diego County Sheriff’s Lt. Gary Steadman said.

Merriman, 25, was taken into custody and booked into the central jail at about 8:30 a.m. He was released shortly after 11 a.m. Sheriff’s Department spokesman Jan Caldwell said she didn’t know if he posted bail or was released on his own recognizance.

Raiders acquire Seymour

Alameda, Calif. — The Oakland Raiders took a big step toward improving their struggling run defense by acquiring five-time Pro Bowl defensive lineman Richard Seymour from the New England Patriots on Sunday.

The move does not come without its risks as the Raiders gave up a first-round pick in 2011, which could be in the top 10 based on Oakland’s recent history, to acquire a lineman who turns 30 next month and is in the final year of a contract paying him $3.7 million this season.

It wasn’t immediately clear what the Lions received for the former New England backup. O’Connell’s arrival gives the Jets four quarterbacks on the roster, with rookie starter Mark Sanchez, veteran Kellen Clemens and Erik Ainge.
