Jamieson celebrates 200m gold with some of mum's home cooking

The 22-year-old, who mostly trains in Bath, was a comfortable winner over Stirling's Jamie Ross (2:16.19) with Edinburgh University's Andrew Rodgie third in 2:16.21

It's been a tough few months for Jamieson, who qualified for the World Championships in Manchester in March but then had to pull out of a GB training camp in Cyprus in May and also missed the ASA National Championships in Sheffield two weeks ago.

"I ruptured ankle ligaments the day after the World trials and I knew it was a really serous injury," he said. "But I had three weeks of intensive physiotherapy at Bath. The support staff were great and now it's absolutely fine.

"It's great to be swimming in Scotland again this week. This is my first Scottish Championships for two years and it's the first time since Christmas since I've seen my family in Robroyston. It's lovely to be staying at home and getting my Mum's home cooking."

Scotland's Hannah Miley had the perfect boost when she cruised to victory over world No.?1 Mireia Belmonte to win the 400m individual medley.

Miley, only third after qualifying, did trail Belmonte after the butterfly leg in the final but the European and Commonwealth Games Champion pulled away to win in 4:37.24. The European short-course champion touched in second in 4:43.36.

"I was very happy with the time and it was good for the confidence," she said.

"It's bound to put fire in her belly for the Worlds but now it's back to some more training before heading China."

City of Glasgow's Robbie Renwick, another of the seven Scots heading for Shanghai, scored a bronze medal in the 100m freestyle behind Preston's Ryan Bennett, who claimed the gold in 50.60.

Renwick set a Scottish record of 49.53 in the event at last month's ASA National Championships, and he admitted he had hoped to go a little faster than his 50.77.
