The duo took a guided tour of the cathedral and grounds before setting off the cannon to mark midday in the Russian city.
“It was very, very nice,” said Coric. “This is my first time here. I heard from many people that it’s actually a very nice city. I’ve been really enjoying it. I think this is one of the best 250’s in the whole year.
“I feel quite good. I’ve had a week and a half of preparation. I’m in very good shape and I’ve been playing very well. I hope I can play well here.”
“It was pretty nice,” said Donskoy. “This is my favourite city and I’m from Moscow! I’ve never been to this place and seen these things. I really enjoyed it. My favourite part was firing the cannon.
“It’s a local tournament for me and it’s my favourite tournament because they really do a good job. I really like the city. I have some of my friends here. I’m feeling good in practice, enjoying the place and preparing for the tournament. I’m just trying to do my best. I enjoy being here every year,” added Donskoy, who is making his sixth main draw appearance at this ATP World Tour 250 indoor hard court tournament.
