Jose Maria Olazabal kept his cards close to his chest after opening practice at Medinah

Jose Maria Olazabal would not be drawn on possible Ryder Cup pairings after the first day of practice at Medinah.

Heart

With two caps McDowell is not sure he has a senior role to play, but Olazabal said: "He is one of our main men, to be honest. "He plays with a lot of heart and loves this competition. Those are elements that are crucial and essential to this tournament. "He will fight until the very end, for every shot, for every inch." Olazabal said he was delighted to see McIlroy in such good form coming into the event. "Obviously we have the world number one, he's playing great," he said. "Even though he didn't win the FedEx Cup (despite winning two of the four play-off events), the way he's played the last few months, he's been outstanding. "I would say that he is at this moment very close to how good Tiger was at that stretch of time between 1999 and 2002, the way he's playing. He's full of confidence. "He's got the whole game and in that regard it's great to have players like that on your team."
