Flashback: How's this for a fired-up Andy on clay!?
I had no idea he and DelPo had this history between them.... and I also think Ivan Lendl would disagree with Andy here.
btw.. DelPo retired in the 3rd.
Murray: Del Potro insulted my mum
Andy Murray claimed opponent Juan Martin Del Potro insulted his mother during his ill-tempered win at the Rome Masters.
Murray will play Stanislas Wawrinka in the second round after Del Potro retired with a back injury in the deciding third set of a game also interrupted by rain.
The players exchanged words during an edgy match - some of them seemingly prompted by Del Potro's criticism of Judy Murray's vocal support for her son - and the Scot said in The Times: "I will accept lots of things, but not when someone insults my mum, the nicest person in the world."
The Argentinian had just been broken to go 1-0 down in the third when he immediately called for the trainer at the change of ends.
Del Potro was in significant pain and appeared to be close to tears but after five minutes' treatment he admitted defeat.
The tide had turned for the world number 17 after he had taken the first set 7-5, losing the second 6-4 and then going behind in the third before injury struck.
It was not the best of matches with rain forcing the players off court after just 13 minutes with the score at 1-1.
When they returned Murray was warned for uttering an audible obscenity and in the next the Scot and Del Potro then exchanged words about their respective behaviour.
The tennis was not up to much either with Murray broken three times and his opponent twice as Del Potro forged ahead 7-5 in the first set. The first six games of the second went with serve before Murray claimed the crucial break.
He was immediately broken back but overcame the Del Potro serve once again and closed out the set 6-4. A third successive service break put him ahead in the third before injury struck.

They have known each other since they were pre-teenage tennis brats. But, in an otherwise inconsequential match in Rome two years ago, Andy Murray and Juan Martín Del Potro swapped invective that shocked the few spectators who had lingered in the cool night air at the Foro Italico to watch two young players reckoned to be leaders of the next generation.
"Always the same," Del Potro said, referring to Judy Murray, who was sitting behind the baseline in passionate support of her son. Murray later denied using the F-word in her defence at a changeover in the second set, but what he did not dispute was the flash of mutual anger that lit up a fractious encounter.
After that first-round match, which Murray won when Del Potro retired with back spasms, their friendship has swayed between indifference and mild warmth. Del Potro went on to win his first grand slam, in New York. Murray did not. But he has twice come close to a slam breakthrough.
If they meet in the fourth round of the Australian Open – not exactly a given, as Del Petro, out for a year, would have to get past Dudi Sela, 21st seed Marcos Baghdatis and 11th seed Jürgen Melzer – the Argentinian says there will be no childish animosity, no tantrums. "We are grown up now," says Del Potro. "Is fine."
