Britain's Andy Murray will have to overcome the big serving of Canadian Milos Raonic if he is to win a record fifth Queen's Club title on Sunday.
Top seed Murray and third seed Raonic meet in the Aegon Championships final at 14:00 BST.
A win would take Murray past four-time champions Boris Becker, Lleyton Hewitt, Andy Roddick and Roy Emerson.
The final will also be the first meeting of former rivals Ivan Lendl and John McEnroe as opposing coaches.
Murray reunited with Lendl this week after the pair split two years ago, while McEnroe - another four-time winner at Queen's - began working with Raonic last month.
