The last time the Ulstermen started a PRO12 campaign with three straight victories was in season 2012/13, where they did not lose their first match until round 12.

Ulster have lost just once at Kingspan Stadium since early January: 20-21 to Scarlets on 21 February.

Scarlets have won only one of their last six Guinness PRO12 fixtures: over Newport Gwent Dragons on "Judgement Day" in April.

Scarlets only victory in their last twelve visits to an Irish province in any tournament was in Belfast in February.

Scarlets won both matches against Ulster in the Guinness PRO12 last season but have never won three in a row against the Irish province.

Overall Guinness PRO12 head to head record:
Played 27, Ulster won 14, Scarlets won 11 and 2 games drawn.
