Beijing Guoan battled from behind to edge Shanghai Port 2-1 on the road in Shanghai on Thursday, remaining undefeated after nine matches and leapfrogging the two-time defending champions for third place in the Chinese Super League (CSL) table.Beijing had to make an early substitution in the 22nd minute, after sending on Wu Shaocong to replace injured captain Wang Gang.Shanghai scored first in the 40th minute, when Mateus Vital's corner found Liu Ruofan for a header.
But the home side's advantage lasted less than 120 seconds.
Dawhan's long pass to Lin Liangming resulted in a close-range shot that was denied by Port goalkeeper Yan Junling, only for Fabio Abreu to knock in the rebound and bring Guoan level.Yan also appeared to have injured himself in the play and was replaced by Chen Wei after halftime.Beijing took the lead 10 minutes into the second 45, as Lin broke into the box and fired a powerful shot into the far top corner of the net.
Guoan had several chances to extend their lead as the game went on.
In the 60th minute, Zhang Yuning's long pass found Abreu, who got past both his defender and the goalkeeper, but sailed his shot wide.Seven minutes later, a mistake by Chen nearly cost Shanghai a third goal.
The substitute  goalkeeper kicked the ball right at Beijing midfielder Zhang Yuan inside the box, but atoned for his error by successfully blocking the ensuing shot.Port had a chance to equalize in the first minute of stoppage time, but Zhang Fanlin's header was parried away by Guoan goalkeeper Hou Sen and the visitors escaped with a hard fought one-goal victory.
