Houston Rockets coach Mike D'Antoni says his team must eradicate mental mistakes to have any chance of levelling their NBA Western Conference finals series against the Golden State Warriors on Wednesday. The top-seeded Rockets suffered a chastening 119-106 home defeat to the reigning NBA champions in game one on Monday. A second victory for Golden State on Wednesday would leave Houston with a mountain to climb when the best-of-seven series heads back to California for game three on Sunday.
