[...] they've done just that, winning six of their last seven games, capped by a 102-93 victory over the Houston Rockets on Wednesday night to improve to 9-7. Jeff Green scored 20 points and Courtney Lee had 10 of his 17 in the fourth quarter to help the Grizzlies beat the struggling Rockets. The Grizzlies led for most of the game despite playing without Zach Randolph, who missed his fourth straight game with soreness in his right knee. The Rockets made eight free throws in the first almost 10 minutes of the fourth quarter, but did not make a field goal until a 3-pointer by Jason Terry cut it to 98-88 with 2:01 remaining. Corey Brewer made a 3-pointer after that, but Lee struck again, making a jump shot seconds later to make it 100-91 with just over a minute left. About the only excitement in the beginning of that quarter came when Dwight Howard and JaMychal Green got tangled up fighting for a rebound and pushed each other, drawing a technical foul for both players. Harden hit a 3-pointer soon after that, but Houston's offense went cold after that and the Rockets didn't make another field goal until a layup by Pat Beverley with 2:18 left in the quarter. Houston rookie first-round pick Sam Dekker was back with the team on Wednesday after having surgery on Friday to repair a herniated disk in his back.
