Takuma Asano struck twice as J. League champions Sanfreece Hiroshima finally put three points on the board with a 3-0 win over Thailand's Buriram United in Group F in the Asian Champions League on Wednesday night.

Hiroshima had not won in any competition since lifting the Xerox Super Cup in the J. League curtain-raiser against Gamba Osaka last month, but Japan Under-23 striker Asano put Sanfrecce on their way with a fine solo first-half effort.

Asano repeated the feat early in the second period before Kohei Shimizu sealed victory with a clinical strike in the 81st minute.
