These 2 have met 6 times before and it's even stevens at 3-3 in the H2H. They have never played on another one grass (Ljubicic was ill during the 2007 Davis Cup Match) Ljubicic had the last win, in China last year.
Came across this whilst checking out Ljubicic photos:-
In the 3 years and over 16,000 challenges, Hawk-Eye produced its worst error in the Murray vs Ljubicic
match at Indian Wells (2009), when a ball which was OUT was shown on the video screens to be IN.http://www.hawkeyeinnovations.co.uk/UserFiles/File/Ljubicic%20Challenge.pdf
