Ross stunned a home crowd this afternoon by qualifying first in the men's 200m breaststroke, breaking the Commonwealth Games record in a new personal best of 2:08.78.
Ross took the lead off of Olympic silver medallist Michael Jamieson in the heats, who qualified second in a time of 2:10.17, with another Scottish swimmer, Callum Tait, taking third place.
His victory came after a strong second half in which Ross closed down Jamieson in the second half after he had taken out an early lead.
Ross seemed confident with the result after the race, "I feel great, and I feel I've got more in the tank." Everyone will be watching to see if he can best his own record tomorrow evening in the 200m final starting after 19:00.
