Harrington, who has won three majors, said in August that Tiger Woods will win again someday.
"I still believe when he turns up and plays well in a given week, I think he's well capable of winning any major he plays in. He still has a good ball flight. He still hits it well. Once he puts it together in a given week, he can win and will going forward. ... OK, it wasn't his week that week. But when it is his week, he will win again," Harrington said.
