Tennis extends use of Hawk-Eye in Davis, Fed Cup
LONDON (AP) -- The International Tennis Federation says it is expanding the use of Hawk-Eye replay technology to all rounds of the Davis Cup and Fed Cup World Groups.
Last year, the ITF used the system from the Davis Cup quarterfinals and Fed Cup semifinals. But the federation has now added Hawk-Eye to the first rounds in both competitions as well as the Fed Cup playoffs.
Hawk-Eye was first used in the Davis Cup for the 2006 final, and was extended to the Fed Cup for the 2007 final.
The replay technology is used only for matches on hard and grass courts.
