Scarlets moved above Munster into second place in Conference B of the Guinness Pro14 after a rousing second-half performance saw them overwhelm the Dragons.

Prop Samson Lee, wings Steff Evans and Johnny McNicholl, flanker James Davies and replacements Tom Rogers and Dane Blacker all crossed the line in an impressive display by the visitors, while Dan Jones booted four conversions and a penalty.

The bonus-point lifts the Scarlets above Munster, who need to claim two match points against Connacht on Sunday to book a semi-final date with Leinster.

Wing Jared Rosser, flanker Taine Basham and centre Adam Warren grabbed the Dragons' tries, with fly-half Sam Davies kicking a penalty and conversion, but they came up short after a promising start.
