HEAT and dehydration caused Aidan McHugh to vomit three times in the course of his first round boys’s single match but by the end it was his opponent who was sick to the pit of his stomach. McHugh will celebrate his 17th birthday today with his first ever Wimbledon singles win, against an opponent in Gianni Ross of the USA who is two years older than he is.

The Bearsden teenager, whose freckles understandably appeared a little more prominent after this one, said he had probably underestimated the London weather, and would be more scrupulous about applying sun block from now on. But his future in the sport appears bright indeed, as he roared back from a 4-1 deficit in the third set to record a fine 6-2, 2-6, 6-4 win. His wasn’t the only great win from a player from Greater Glasgow yesterday, with Hamish Stewart from Strathblane also rallying superbly for a 4-6, 7-5, 6-1 win on Court No 16 in only marginally less dramatic fashion.

McHugh - who was offered assistance from the on-site medics and his father Chris, who is also a doctor - was delighted afterwards that he displayed the guts to get the win. When it became clear that he had expend less energy, not more, he had the temerity to tell even his support team to calm down.

“I was sick twice on court, and once in the toilet after the second set,” said McHugh, blessed with a particularly Scottish complexion. “I spoke to the doctor after it and obviously my dad is a doctor as well. I’m not too sure what it was, whether it was to do with eating before it, or a combination of things with the heat.

“I didn’t have sun cream on, maybe it is because of that,” he added. “Maybe I underestimated it a little bit because it is England. I’ve played in the 40s before but when I’m abroad I do usually have ice and things to cool me down. I got the ice towel which helped.

“I was just trying to find any way I could to break him and be really efficient with the energy. I started playing a bit quicker, serve and volleying a bit more.”

McHugh, who has been taken by Jamie Murray to Miami and Monte Carlo, and given practice time with Andy Murray at least three times in the last week or so, also got a nudge in the right direction from the World No yesterday. “Andy actually bumped me as a joke just when I was getting my bag to go on court, he poked me in the ribs or something,” said McHugh. “It was just him, being an idiot. No, I told him I was on, and he just said good luck. I came in with a lot of practice and preparation for it on the grass but it was good that I found a way to win because it was obviously very tough to be in that situation.”

While McHugh still has time on his side, this is Stewart’s last chance to make a mark at junior Wimbledon and he did so in style with a 4-6, 7-5, 6-1 win against Tomas Machac of the Czech Republic. Knowing he probably wouldn’t have been a recipient of a wild card were it not for a win against the No 1 seed Corentin Moutet at an ITF junior event in Roehampton last week, Stewart made the most of it.

Next for him once he exits SW19 is a tennis scholarship alongside Ewan Moore at Tulane in the USA and a trip to the Bahamas for the Commonwealth Youth Games. “Before Roehampton I probably wasn’t going to get the wild card but then after qualifying and getting a good win in the first round they took a punt me and I guess it worked out,” he said. “It was an unbelievable experience, so much fun.”
