Former U.S. Open champ Andy Roddick may be retired from tennis, but Tuesday morning he put his athletic skills to good use.

"I ran faster than I have in about five years, and this was a good reminder of why I retired," laughed Roddick.

His efforts all went to a good cause.

Alongside RetailMeNot, Roddick and members of the Andy Roddick Foundation (ARF) raced throughout Sam's Club collecting as many materials as they could in two minutes. Those materials will go towards ARF's summer programs this summer, which will work with 1,500 campers.

"It's great. First of all, we have to give a huge thank you to RetailMeNot for allowing us to organize and coordinating with Sam's Club. This is the third year we've been able to come out here and grab the bulk of our supplies," Roddick said as he stood in front of cartloads of goods.

In just two minutes, Roddick and his teammates grabbed nearly $8,400 worth of materials ranging from drinks, classroom utensils and sunscreen.

"Luckily we have a great staff at our foundation, and they kind of plot out the routes based off what they think the kids need the most," Roddick explained.

"It's really interesting because even to us who aren't necessarily on the ground, seeing everything that goes in and out, day to day at the (Andy Roddick Foundation), RetailMeNot knows that behind-the-scenes there's so much work taking place. And it's fantastic that we're able to help out and provide basic, basic supplies like paper towels, paper plates, sunscreen. Sunscreen gets expensive, and not a lot of kids have access every day to it as they should," said Sara Skirboll, a spokesperson with RetailMeNot.

During his illustrious career, Roddick walked off the court as a victor nearly 700 times. But despite his personal success on the court, he stressed the focus of his camp was far-reaching.

"We want to teach life. You know if that's sports and nutrition, great. But just because I played tennis doesn't mean that's what they have to do. I think exposure to financial literacy at a young age, tech literacy at a young age, different sort of STEM programs, working groups - we want them to be able to have a conversation with another person to fix a problem. These are all things that are very important," said Roddick.

This summer, the program has expanded to Harris Elementary, which joins Pecan Springs Elementary as host sites.

"The high-level discussions when we decided to take ownership over our own programs is ‘listen, let’s get it right first, then let’s rinse and repeat and expand without losing the quality of our first programs which have gone over really well.' We look at it as a great opportunity, and we want to expand every summer. That’s the goal," said Roddick.
