Halfpenny converted, before Wales nearly conjured a spectacular try when forwards Shingler, Hill, Rob Evans and Alun Wyn Jones combined brilliantly, but Steff Evans dropped Jones' pass just five metres from Scotland's line.
Rob Evans, Ken Owens and Samson Lee will form the first all-Scarlets front row to have started for Wales since 1891.
"On the back of a year ago, I think that would be fair", said Jones.
There's a fair chance it will be a close game, but I think if Wales play loosely it will suit us because Scotland want to play a very fast game.
"He's probably the best full-back Scotland have ever had and that's a big call when you've got people like Chris Paterson, Gavin Hastings and Andy Irvine", Logan, speaking courtesy of Robert Walters, told Omnisport.
"We knew Wales were going to be unsafe and we missed a lot of tackles in the middle of the pitch". We pride ourselves on our scrummaging and it is something we work hard on.
"We were badly beaten and it was a defeat, but there weren't many away wins in the championship a year ago and now we need to bounce back".
"It's about us sticking to our processes and what we are trying to achieve, although the biggest thing is being disciplined and not giving away penalties".
Someone said to me at the Six Nations launch that apart from the games against Italy, only England won an away game in last year's tournament with that last-minute try in Wales.
In Austin, Rex Tillerson lays out Trump agenda for hemisphere

NOT for the first time - and doubtless not for the last - the promise of Autumn gave way to the harsh reality of Spring, and a rugby nation which has been through this painful process more times than anyone would care to count has been left scratching their collective heads and wondering how they managed to fall into the same trap again.
"Last year, there was X-amount of years they hadn't had a win against us and we went up there and we lost", said the 32-year-old.
"The favourites tag isn't something that we've talked about or worry about".
Scotland's 36-year-old hooker Scott Lawson, who has not played an global since 2014, provides cover on the bench in a further reflection of the selection crisis among the forwards for coach Gregor Townsend.
And there were only five minutes to the break when Wales came under sustained pressure for the first time, facing a five-metre attacking Scottish scrum, but a handling error in midfield thwarted the Scots and Wales surged upfield through centre Hadleigh Parkes' lengthy touch-finder.
Ali Price and Finn Russell form a risky half back partnership.
Scotland: Hogg; Seymour, Harris, H Jones, McGuigan; Russell, Price; Reid, McInally, Welsh, Toolis, Gray, Barclay (captain), Watson, du Preez.
"They have picked a lot of Scarlets players and the Scarlets style is different".
"The best ball you can play off is forcing turnovers and if the opposition are going to play more, that means there are more opportunities for us to get turnovers".
