OKLAHOMA — The Oklahoma City Thunder traded James Harden to the Houston Rockets Saturday after the Western Conference champions were unable to reach an extension agreement with NBA's Sixth Man of the Year. In the multi-player trade, the Thunder acquired guards Kevin Martin and Jeremy Lamb, two first round picks and a second round pick while center Cole Aldrich and forwards Daequan Cook and Lazar Hayward went the other way along with Harden. “We wanted to sign James to an extension, but in the end, these situations have to work for all those involved,” Thunder GM said. — AP
