This is WEEKEND EDITION from NPR News. Good morning, I'm David Greene.
It's been pretty warm here on the East Coast the last few days. No, check that - it has been downright scorching. Temperatures have climbed so high many cities warned residents that they should avoid strenuous activity and stay hydrated.
From member station WHYY, Elizabeth Fiedler reports on how some are beating the heat in Philadelphia.
SISTER WINONA CARR: (Singing) Life is a ball game being played each day. Life is a ball game...
DAVID GREENE, HOST:
That big stadium organ in that tune seems so appropriate this week because the Major League Baseball is heading into its All-Star break. And WEEKEND EDITION star, Mike Pesca joins us now to talk sports.
MIKE PESCA, BYLINE: Thanks. I was named in fan balloting. I don't really deserve it.
The men's Wimbledon final has just ended, and Swiss star Roger Federer has now tied Pete Sampras' all-time record of seven Wimbledon victories in the modern era. It was a dramatic win for Federer, but also a dramatic loss for Britain's Andy Murray, who had a whole country watching today. He was the first British man to even reach the Wimbledon finals in 74 years. Like millions of people all over Britain, NPR's Philip Reeves tuned in. And, Phil, are you still breathless after that match?
And let's talk about the presidential campaign with Mara Liasson, NPR's national political correspondent. Mara, good morning.
MARA LIASSON, BYLINE: Good morning, David.

Old Crow Medicine Show didn't count on the runaway success of its 2004 song "Wagon Wheel." In fact, say members Ketch Secor and Critter Fuqua, the Nashville band was just trying to finish a job Bob Dylan had started.
The NAACP, the nation's oldest civil rights organization, holds its annual convention in Houston this week. As in any election season, the group is focused on voting rights and voter turnout.

Presidential candidate Mitt Romney will address the NAACP convention on Wednesday, and Vice President Joe Biden is scheduled to speak the following day. NAACP members are ready to hear their plans.
