Japan midfielder Yasuhito Endo stroked home a late penalty to rescue Gamba Osaka a 1-1 draw in the first leg of its Asian Champions League semifinal against bitter J. League rival Urawa Reds on Wednesday.

Defending champion Urawa looked to have gained the upper hand and a measure of revenge for an ugly defeat at home to Gamba in the J. League in the summer through Hajime Hosogai's well-taken strike after 22 minutes.

But Endo ensured it was honors even when he sent Ryota Tsuzuki the wrong way from the spot nine minutes from time after Takahito Soma had been penalized for pushing over Ryuji Bando in the box.
