Ian Poulter shot 7-under 65 and overcame a four-stroke deficit Sunday in China for the WGC-HSBC Champions victory.
Poulter, whose passion and persistence helped catapult the European squad to victory at the Ryder Cup this year, had eight birdies against one bogey in the final round to finish at 21-under 267 overall on the Olazabal Course at Mission Hills Golf Club.
The two-shot victory in China was Poulter's second WGC title, his first coming at the 2010 Accenture Match Play. Poulter’s 21-under-par total also set a new tournament low score in relation to par and is the third-lowest total by a winner in World Golf Championships history.
'It's just so nice to get my hands on another trophy,' Poulter said.
Lee Westwood co-led through 54 holes after a third-round 61 – his lowest round in a World Golf Championships event – but shot 72 Sunday to finish T-6.
Els played the front nine in 18 under par and the back nine in 1 under par en route to his second career runner-up finish at the HSBC Champions. Els also finished runner-up at this event in 2009.
Mickelson, the only two-time winner of the tournament (2007, 2009), battled for the lead but bogeyed the 12th after missing a 5-footer by an inch.
Defending champion Martin Kaymer looked set to make a final-day comeback but was unable to do so. He began Round 4 six shots back, and had five birdies in six holes on the back nine before a triple bogey on the 17th foiled his chances. He ended up in ninth place, one stroke behind Adam Scott (67).
