LeBron James dominated the game with his size and strength on both ends, and Dwyane Wade scored 19 points to give the United States a 97-76 victory over Angola on Tuesday at the Olympics. Dwight Howard added 14 points and James finished with 12 for the Americans, who had another rough night from 3-point range but don't appear to be stoppable in the open court. Wade was perfect from the field until missing in the third quarter. Earlier, Pau Gasol scored 29 points to lead world champion Spain over Yao Ming and host China 85-75 in overtime. Spain, which finished out of the medals at Athens in 2004, remains unbeaten in Group B with four points and next faces Germany on Thursday. China is without a win after two games, including a 101-80 drubbing at the hands of tournament favorites the United States. Also in Group B, Vasileios Spanoulis and a dogged Greek defense curbed Dirk Nowitzki in a 87-64 win over Germany in Group B. The United States improved to 4-0 against Angola, starting with the Dream Team's Olympic debut in 1992. The Americans (2-0) moved on to face Greece, the team that stunned them two years ago in the semifinals of the world championship. Two days later comes a matchup with Spain, the team that won that tournament and is also 2-0 in this one. Greece stunned the United States 101-95 two years ago in the semifinals of the world championships in Japan. This US team is much deeper, and James is a whole lot stronger. The Spaniards showed their quality in a dramatic game that had them trailing for much of the last three quarters. Battling back from a 14-point deficit at the end of the third period, Juan Carlos Navarro tied the score at 70-70 with two minutes to go. In Group A, Linas Kleiza scored 22 points to lead unbeaten Lithuania to a 99-67 victory over Asian champion Iran. Sarunas Jasikevicius added 20 points while Hamed Ehadadi had 21 points for Iran, which is winless after two games. Croatia beat European champion Russia 85-78. Marko Popovic led Croatia with 22 points, while captain Andrey Kirilenko led Russia with 18. – AP __
