In the round of 16 of the ATP tournament in Rotterdam, it was 5-5 in the first set between Andy Murray and world eighth Andrej Rublev.
The British served, and the Russian had a chance to break.
Murray missed his first serve, and so did others who went straight into the net.
In frustration, Murray swung his racket rock hard straight into the ground - and was forced to change.
- I should have won the first set.
I was not good enough in my server game that I lost.
I'm not used to making mistakes at that stage of the match, says Andy Murray.
"Affected me"
Rublev then kept his serve and won the first set 7-5.
The second set was far from as even, and Rublev took it home with 6-2.
- Then he was much better than me.
Plus I have a tendency to dwell on mistakes, and that affected me.
In the quarterfinals, Rublev will face the winner between David Goffin, Belgium, and Jeremy Chardy, France.
