Lowry leads Irish charge but Yang commands China Open
Yang, who finished eighth at The Masters last week, embarked on a back-nine birdie blitz to close on his equally in-form but lesser known compatriot.
With Kim topping the second round leaderboard at 11-under-par after a three-under 69, Yang closed with four consecutive birdies which keyed a six-under-par 66 to earn a share of second alongside Asian number one Thongchai Jaidee and Welshman Jamie Donaldson.
