Hardy Norseman Casper Ruud felt nothing but comfortable on Friday as Monte Carlo spring conditions turned chilly during his 6-4, 6-3 upset of holder Fabio Fognini.
The tennis Viking took little notice of 12 Celsius conditions, which arrived to replace the warmer feel of earlier rounds.
For the 27th-ranked Ruud, conditions were close to perfect.
“I grew up playing tennis like this in the spring and summertime in Norway. It’s usually cold,” he said.
“It’s not as cold as today in the summertime in Norway, but in the spring and early summer it’s usually like that: 12, 13, 14 degrees with rain in the air.”
While Fognini from just down the Mediterranean coast over the Italian border, may not have found all to his liking, Ruud lapped it up.
But he also admitted that training in warm-weather Spain is also a big part of his regular programme.
“I’ve escaped a little bit to Spain to get good practices down there. Tour players are usually in hot places, big cities, where it’s warm.
“Fognini is from Italy, so probably didn’t experience these conditions too much.”
Ruud said that it’s his tennis and not the weather that will ultimately make the difference.
“We’re here in Monte-Carlo, and you think it will be 20 degrees and sunny, no wind. The last days have been cold, windy, not what you’re expecting.
“But I guess I’m liking it so far.”
