Russell restart try 'big moment' in Scotland win, says Townsend
The Scots trailed for most of the game as they took on a Wales side who had lost 23 of their last 25 Tests, only taking the lead with George Turner's 75th-minute try.
"That was some game. It would have been great for the neutrals," Townsend told the BBC.
"We left it late but I'm really proud of the effort in the second half.
"It's not just a physical effort, it's a mental effort too; finding solutions, staying together and riding momentum waves."
The match turned on two Scotland tries in the space of three minutes...
