Scarlets moved back to the top of the Pro12 thanks to their third win of the season against Zebre in Parma.
The Welsh region trailed 8-6 at the interval after wing Mattia Bellini crossed for the Italian side.
Flanker James Davies sparked a Scarlets revival with a try early after the break with Dan Jones and Steven Shingler kicking the remaining points.
A yellow card for second row George Earle made for a frantic finish, with Zebre battering a stubborn defence.
Scarlets coach Wayne Pivac: "We're happy with the points, but not happy with the performance, particularly in the first half - across the park.
"We spoke at half time and rectified some of it in the second half, but we fell away from the standards we set in the first two games of the season and as a result it was stop start and there were too many turnovers.
"We've set a target of being in the top four when the players come back from the World Cup, but hopefully they won't be back for a while yet."
