Jeonbuk Hyundai Motors buried Urawa Red Diamonds with a second-half treble and Kashiwa Reysol fired six past hapless Suwon Bluewings in an entertaining evening in the AFC Champions League on Wednesday.
Jeonbuk took a beating from Urawa, their fellow former Asian champions, in the first 45 at Saitama. But the Reds were left to rue a hatful of missed chances when their Korean visitors struck three times in 20 minutes to win the Group F tie 3-1.
But Jeonbuk's flurry of goals was eclipsed in Suwon, where the Korean hosts missed three penalties during a crazy encounter which featured seven second-half goals and ended 6-2 for Kashiwa, who extended their Group H lead.
Earlier, Australia's Central Coast Mariners kept their hopes alive despite a late own goal when they beat Guizhou Renhe 2-1 for their first win. Marcello Lippi's Guangzhou Evergrande were playing Muangthong United in a later kick-off.
In the clash of Jeonbuk and Urawa, the winners in 2006 and 2007 respectively, the Japanese side got on the score sheet early when Genki Haraguchi, capitalising on Tomoaki Makino's mazy dribble into the box, belted them in front on six minutes.
Haraguchi should have doubled the lead five minutes later, and Brazilian Marcio Richardes rifled just wide and then hit the post, as the home team went on the rampage.
Haraguchi was also denied from a close-range header just before the break.
Yosuke Kashiwagi put it over the bar early in the second half, but Jeonbuk came roaring back when Lee Seung-Gi buried a screaming strike, teed up on the edge of the box after a free-kick, on 51 minutes to level the scores at 1-1.
Substitute striker Lee Dong-Gook put the visitors ahead when he arrowed a diving header, from another free-kick, into the top of the Urawa goal.
And Brazilian midfielder Eninho doused any hopes of a comeback with a magical effort with 20 minutes to go, when he spotted the Urawa 'keeper off his line and hit a swerving shot over him and into the goal from a distance.
With the win, Jeonbuk took the provisional lead in Group F ahead of the result between Guangzhou and Thailand's Muangthong.
In Suwon, Junya Tanaka put visitors Kashiwa ahead on 16 minutes but the game suddenly came alive in the second half when Dzenan Radoncic's penalty miss was followed by three goals in quick succession for 3-1.
Jong Tae-Se's fluffed penalty was then followed immediately by Tanaka's second strike to make it 4-1. Stevica Ristic finally scored a penalty for Suwon for 4-2, but there was still time for another penalty miss as Ryoichi Kurisawa and Masato Kudo both grabbed their second goals to round off the scoring.
Earlier Australia's Mariners, who had won only one of 14 previous ACL games, had looked set for further heartbreak against Guizhou after an unfortunate own goal by goalkeeper Mat Ryan cancelled out Pedj Bojic's spectacular 50th-minute opener.
But with nine minutes left, New Zealand international Michael McGlinchey whipped in a tantalising cross for the unmarked Trent Sainsbury to head in at the far post and lift the Mariners to second in Group H, behind runaway leaders Kashiwa.
"We made it real hard for ourselves," Mariners coach Graham Arnold said. "We should have been up 3-0."
