Former world number one Marat Safin has joined a high-quality field for this year's Artois Championships at Queen's Club in London.
Safin will try to overcome his well-known dislike for grass
The Russian will line up with world number two Rafael Nadal, defending champion Lleyton Hewitt, Andy Roddick and Britons Andy Murray and Tim Henman.
Hawk-Eye, the electronic line-calling system, will make its British and grass-court debut at the event.
This year's tournament takes place from 11-17 June.
