Hawk-Eye on Federer's dominant serve
Roger Federer beats Lleyton Hewitt 6-3 6-4 7-6 (7-5) to reach his third straight Wimbledon final.
Here Hawk-Eye helps demonstrate how the defending champion's serve helped him dominate the match.
In the first set, Federer got just 37% of first serves in, giving Hewitt lots of opportunities at the Swiss' second serve, but he failed to take advantage. Hewitt only won 53% of points on Federer's second serve - disappointing for one of the best returners in the game.
While Federer improved his first serve in the second set, Hewitt won just 12% when returning the second serve, so still could not exploit Federer's weakness.
Hewitt tried to be more effective in the third set by stepping inside the baseline in the third set, but he failed to get any break points in the second or third sets. Because his return was so ineffective (Federer won 86% of points on his first serve) and Hewitt's own first serve was so poor - he made just 46% of first serves - he could simply not compete with Federer.
