SAITAMA, Japan (AP) — A’ja Wilson had 19 points and 13 rebounds in her Olympic debut to help the U.S. beat Nigeria 81-72 in the opener for both teams. The win was the Americans’ 50th consecutive victory in the Olympics dating back to a loss in the semifinals of the 1992 Barcelona Games. Diana Taurasi, who was playing in her first game in nearly a month after suffering a hip injury, has competed in the last 33 of those victories to set a record for most games in the Olympics. Ezinne Kalu scored 16 to lead Nigeria.
