President Obama hit the golf course Saturday for what, by CBS News' Mark Knoller's calculation, was his 52nd such outing since taking office.

According to the White House pool report, Obama went golfing Saturday with his usual partners: trip director Marvin Nicholson, press aide Ben Finkenbinder and the Department of Energy's David Katz.

CBS News Radio White House correspondent Knoller tweeted:

It's a beautiful 77° & sunny in DC and Pres Obama has gone to Andrews AFB for a round of golf. His 52nd since taking office.

Before heading to Andrews Air Force Base for golf, Obama watched his daughter Malia's soccer game in northwest Washington.

Obama heads to Philadelphia with Vice President Biden on Sunday for a DNC "Moving America Forward" campaign rally with Democratic Senate candidate Rep. Joe Sestak (Pa.).
