Two good causes power the annual “Night at the Net” benefit, whose sporty theme means jeans and tennis duds, not tuxedos, are suggested attire. Celebrities will include Chicago Blackhawk Brent Sopel, television nutritionist Sandy Goldberg and sportscaster and author Rich King.

Hosted by the Hinsdale Racquet Club, the fourth annual event offers women nonstop tennis at all levels of play, with swing advice from the pros. Both genders can head outdoors to a heated tent filled with table games, a cigar area and music. Food, drinks and surprise celebrities round out the event.

“We’ve always done something that would impact both breast cancer and blindness,” said Nancy Pollak of Burr Ridge, who has co-chaired the benefit since its start.

Last year’s event raised $40,000. The Foundation Fighting Blindness, of which Pollak is a volunteer, is a regular recipient. This year’s breast cancer charity is A Silver Lining Foundation, founded by Goldberg.

Co-chairing the benefit is Kelly Sopel of Hinsdale, whose husband, Brent, is lending an assist.

“My wife has been doing a lot of legwork,” said the defenseman for the red-hot Blackhawks. “I’m helping make phone calls to businesses to get some donations and to get some people that I know who haven’t been to this event (before) out there to raise money for a great cause. We’re trying to make this as big as we can.”

Brent Sopel might not be the only pro hockey player at the event.

“I’ve talked to a few teammates,” he said. “It will be a lot of fun.”

Proceeds from the benefit will support A Silver Lining Foundation’s project to provide cost-free mammograms and follow-up diagnostic testing.

Goldberg, a breast cancer survivor, created the foundation after seeing a disparity in medical and preventive care for women with less financial resources.

On her Web site (www.asilverliningfoundation.org), she explains her inspiration.

“At that moment, I heard my mom’s voice: She had two favorite sayings: ‘There is always a silver lining’ and ‘We are all family, and we have to help each other through the tough times.’”

Goldberg crossed paths with Pollak at a fundraiser for the Foundation Fighting Blindness, which targets retinal diseases (www.fightblindness.org).

“We’ve become friends over the years,” Pollak said. “ I think the work she is doing is just tremendous, and we want to help her.”

King, an award-winning sportscaster, wrote the book “My Maggie” about his late wife’s battles with both cancer and with Usher Syndrome, which steals sight and hearing. He will sign copies of his “love story” tribute to her remarkable life, donating a portion of proceeds to the benefit. (Visit www.mymaggieslegacy.com.)

The Blackhawks organization helped arrange for the table games, which will include air hockey, stick hockey and ping pong. Donated by Killerspin and Carrom, the games will be auctioned at the end of the evening, Pollak said.

Businesses generously donated items for the silent auction, spanning diamond earrings, autographed Chicago Cub Alfonso Soriano pink bats (bats tinted pink to raise cancer awareness), a home wine and appetizer party, a Blackhawks package, and restaurant dining, including dinner for 10 at Topaz in Burr Ridge. Among the sponsors is Suburban Life.

“The Hinsdale Racquet Club (has) been gracious enough to allow us to come and use their facilities to make a difference,” Pollak added.

The outdoor tent, a big hit when it debuted last year, was the brainchild of Ted Shepherd of Hinsdale, whose wife, Sarah, co-chaired the benefit the first three years.

“It’s a casual, laid-back event,” Pollak said. “It’s a local grassroots effort, (with the) community coming together for these great causes.”
