McIlroy and Westwood now have a chance to replace Donald at No. 1 in the world if either were to win Titleist - 712 AP2 Forged Irons
this week.
"Obviously, it's another incentive waking up each morning and knowing that if you win your match at the end of that day, at the end of the week you could be world No. 1," McIlroy said.
Donald will head home to Florida to shake off a poor start to his season.
"It's a terrible ride home, believe me," said Els, who has lost five times in the opening round. "I feel for Luke. He's got a lot of pressure on him. Yeah, I know exactly what it feels like." Titleist - 712 AP2 Forged Irons

Fernandez-Castano got some attention this week for saying Woods was "beatable" and not at his best. "He's beatable, too," Woods replied, and the way they played, both were right.
Woods lost the opening two holes and looked as though he might fall 3 down until making a 10-foot par save. Woods won three of the next five holes, one of them with a 50-foot birdie putt, and that's when the match became a case of give-and-take.
He wasn't wild all the time, but it cost him when he was: a left-handed shot out of the desert on No. 2; too much club that sent him over the 11th green and into the desert. But he settled down right about the time the Spaniard began to struggle with the Titleist - 712 AP2 Forged Irons , missing putts inside 10 feet on the 15th and 16th holes that enabled Woods to take the lead.
"I think if there was one day to beat Tiger Woods, this was it," Fernandez-Castano said. "I didn't take the opportunity. I missed a few shots. And of course, you can't miss spots if you want to beat one of the greatest in history."
Johnson had no business winning his Titleist - 712 AP2 Forged Irons .
He already was 3 down when he drove into the desert. He was given relief, but didn't check the path of his swing, and his club hit a cactus on the way back, leading to a muffed shot that stayed in the desert and required a penalty drop. He was hitting his fourth shot from the desert. Furyk was hitting his third from the desert.
Johnson wound up winning the hole with a bogey.
He managed to take the lead going to the 18th, only to bogey. Then, on the par-5 second hole, Johnson had to take another penalty drop from the desert and appeared to be beaten until Furyk chopped up the rest of the hole for bogey Titleist - 712 AP2 Forged Irons
