SAITAMA, Japan (AP) — The former champions Urawa Reds scored three second-half goals in a 4-1 Group F win over Thailand's Muangthong United on Tuesday to register their first victory in the Asian Champions League since 2008 while tournament newcomer Tractorsazi of Iran remained undefeated after a 3-3 draw with Qatar's El Jaish.

Yosuke Kashiwagi opened the scoring for the 2007 champions in the eighth minute and Urawa got an added advantage when Muangthong defender Piyaphon Buntao was sent off after collecting his second yellow card, leaving the visitors with 10 men for the last hour.

Kunimitsu Sekiguchi doubled the lead in the 64th minute with a shot from the left side before a header from Genki Haraguchi and an own goal from Thritthi Nonsrichai extended Urawa's lead to 4-0. Siaka Dagno scored a late consolation goal for the Thai champions.

In the other Group F match, striker Muriqui scored a 64th-minute equalizer for Chinese Super League champion Guangzhou Evergrande to secure a 1-1 draw with Jeonbuk Motos of South Korea.

Marcello Lippi's Guangzhou squad, which opened with a 3-0 win over Urawa Reds two weeks ago, leads the group with four points.

There were two 0-0 draws in Group E, with China's Jiangsu Sainty holding J-League club Vegalta Sendai scoreless and Buriram United and K-League champion FC Seoul maintaining their unbeaten starts with a scoreless draw in Thailand.

Seoul opened the tournament with a 5-1 win over Jiangsu Sainty two weeks ago, but was unable to find a breakthrough at Buriram.

"We are not disappointed with the draw. We are very tired but satisfied with the result as this is a very tough away fixture, FC Seoul coach Choi Yong-soo said.

Tractorsazi substitute Geilson scored in stoppage time to earn a draw against El Jaish that kept the Iranian side top of Group A.

Flávio Paixao gave the Iranians a 24th minute lead, only for Wagner Ribeiro to equalize in the 35th with the first of his two goals. Five minutes after the restart, Mehdi Seyed Salehi restored Tractorsazi's lead, which lasted until the 67th when Adriano slotted home a penalty. El Jaish looked set for an unlikely victory when Ribeiro scored in the 87th with a well-taken, left-footed effort, but Geilson's late header made it all-square.

In the other Group A encounter, the United Arab Emirates club Al Jazira earned its first point of the competition with a 1-1 draw with Saudi Arabia's Al Shabab.

The Saudi club opened the scoring a minute before halftime, when Argentine striker Sebastian Tagliabue picked out onrushing defender Hassan Fallatah, who swept the ball into the corner of the net.

But five minutes before the hour mark, Al Jazira equalized courtesy of a 40-yard (meter) strike from Khamis Esmaeel whose long-distance ball deceived Al Shabab's keeper Waleed Abdullah.

Uzbekistan's Pakhtakor remained top of Group B after edging the United Arab Emirates club Al Shabab 1-0. Pakhtakor's Jamshid Isakanderov scored five minutes from time to give the Uzbek champion its second win in a row in the competition.

In the other Group B match, Saudi Arabia's Al Ettifaq and Qatar's Lekhwiya played to a scoreless draw.
