England's former world No.1 Rose carded a one-under-par 71 on Friday to cling to the 36-hole lead at eight under, holing a clutch par putt on the last with his rivals circling.
America's Bryson DeChambeau chipped in from a bunker on the way to a four-under 68, stalking Rose a shot back in outright second.
