Harden hurting the Mavs

OKLAHOMA CITY -- Kevin Durant has 20 points and 10 rebounds, but the Mavs have done another solid defensive job on the Thunder star, who is 7-of-22 from the floor.

It's rookie swingman James Harden who is really hurting the Mavs.

Harden has 17 points (5-7 FG), six assists and five rebounds in 29 minutes off the bench. Oklahoma City has a 20-point advantage with him on the floor.

The Mavs managed to cut the Thunder's lead to single digits midway through the fourth quarter. Harden responded with a 3-pointer the next possession.
