QINGDAO, China - Defending champions the Guangdong Southern Tigers came back from 19 points down to beat the Beijing Ducks 111-109 in overtime, and take a 1-0 lead in the best-of-three Chinese Basketball Association (CBA) semifinals here on Tuesday.

Ekpe Udoh shone in the following quarter with 15 points and helped Beijing take a nine-point advantage, while Guangdong center Zeng Fanri received a disqualifying foul.

After Zhai Xiaochuan scored eight points in a row, the Ducks enlarged their margin to 17 points in the third quarter and seemed in control.

However, with the help of a 15-0 run in the last quarter, Guangdong managed to narrow the gap from 19 points to just four.

Weems hit a buzzer-beater to tie the game 104-104 and force the overtime, in which Taruike Jianiyou and Lin were fouled out and Guangdong maintained a two-point lead until the end.

For Beijing, Fang Shuo had a team-high 28 points, Lin finished with 23 points, Zhai notched 18 points, and Udoh collected 17 points.

"It was such a hard game. Despite falling behind with 19 points, the players didn't give up and fought back. I am so proud of my brothers," said Guangdong head coach Du Feng.

"When the opponents changed their defense to full-court press, we got too many fouls. We still have a chance to bounce back as this is a best-of-three series," said Xie Libin, acting head coach of Beijing.
