Daichi Kamada struck a second-half equalizer to earn Sagan Tosu a 1-1 draw away to treble winners Gamba Osaka in the J. League first division on Wednesday night.

Former Japan international Yasuhito Endo put Gamba in front from the penalty spot late in the first half but Kamada lashed home to earn Tosu a share of the spoils with 19 minutes left.

The result leaves both teams with five points from four games in the second stage, four behind leader Sanfrecce Hiroshima, which has played a game less.

Takashi Usami and Hiroyuki Abe both had chances in the first half at a rain-soaked Expo '70 Stadium but Gamba took the lead through Endo's spot kick six minutes before halftime.

Shu Kurata earned the penalty after he was bundled over in the box and Endo made no mistake, drilling his shot past Taku Akahoshi and into the right-hand corner.

Gamba had another penalty shout a minute before the break when Usami went down with Akahoshi diving at his feet, but referee Yoshiro Imamura waved it away.

Patric should have doubled the lead midway through the second half, the burly Brazilian striker squandering a free header and sent it over the bar.

Tosu had a great chance to punish that miss at the other end moments later, Kota Mizunuma scuffing his shot wide from close range, but the visitors leveled on 71 minutes, Kamada drilling home after a cut back from Kim Min-woo.
