Russell Westbrook had mixed feelings after his Rockets debut ended in defeat to the Raptors in Tokyo.

Lining up alongside James Harden for the first time since the two former NBA MVPs were reunited with his offseason trade, Westbrook scored 13 points, adding six assists, two rebounds and a steal in a 21-minute outing.

Harden impressed with a game-high 34 points, but the Rockets went down 134-129 in Tuesday's preseason game. The two teams will do it all again in Japan's capital on Thursday.

"It wasn't bad -- unfortunately we didn't win and that's the main goal," Westbrook said. "But it was good to get on the floor for the first time, get up and down, try to find a rhythm. We've got a lot of work to do, including myself getting in better shape and game condition, so we'll get it together.
