The pair were tied for the lead through 36 holes but although Yang fell behind Lee early in her round she produced a run of five consecutive birdies from the 4th which swept her to a three-shot lead at that point.
Lee though would reel off a back nine of 32 and all but catch Yang who was forced to birdie two of her last three holes to hold Lee at bay.
Lee actually drew level mid-way through the final nine but the lady with an amazing record in this event and one of the game’s best swings of either gender was up to the task over the closing few holes.
Lee's game appears to be now on song following a slow start to the year in events in Australia and now she has found form then yet another LPGA Tour title seems close at hand
Spain’s Carlota Ciganda put the cat amongst the pigeons when she too moved into a share of the lead with a birdie at the 14th and an eagle 2 at the 16th to move to 20 under par but she would eventually finish in third place two from the lead.
It was Yang’s fifth LPGA Tour title but she is undoubtedly a much better player than her winning record would suggest although she has also won three Ladies European Tour titles, one of those as an amateur when winning the Australian Ladies Masters in 2006.
Katherine Kirk was the next best of the Australians behind Lee sharing 19th place with New Zealand’s Lydia Ko.
Sarah-Jane Smith was 58th and Su Oh 67th.
The LPGA Tour now heads south to Singapore for the rather grandly named HSBC Women’s World Championship.
