A sloppy finish cost Rory McIlroy the chance of a second straight day in the outright lead at the DP World Tour Championship, while a lucky break kept Collin Morikawa on course to become the first American to win the Race to Dubai.
The drama in the second round of the European Tour's season-ending event was reserved for the final hour at Jumeirah Golf Estates -- and the tournament's two headline players were at the centre of it.
Morikawa pushed his tee shot at the par-3 17th hole and the ball bounced in the rough toward the water, only for it to hit a hazard post and stay dry.
An up-and-down for par followed by a final-hole birdie saw the British Open champion shoot a second straight 4-under 68, leaving him three shots off the lead and in a strong position to finish the season as European No. 1.
McIlroy, the first-round leader, reached the 18th tee with a one-stroke advantage but after driving into a bunker, his third shot kicked left short of the green and dribbled into the water.
McIlroy, seeking back-to-back wins after victory at the CJ Cup on the U.S. PGA Tour last month, will play with Morikawa in the third round.
