Red-hot Oliver does the 'trick
Skerries flanker Conor Oliver crossed for a hat-trick of tries as Leinster crushed Connacht at Naas RFC.
Conor O'Brien had put Leinster in front with a fine effort and David McDermott's 64th-minute try put the seal on a fine win after Michael Green's penalties had kept Connacht on the board.
Leinster take on Munster at Thomond Park next week.
Munster were always in control after building up an early 15-point advantage in this clash.
Fionn McGibney converted Ronan O'Hara's try; Eoin O'Carroll went over and McGibney kicked a penalty before Ulster, after missing a couple of kickable penalties, had a Graham Currie try before the interval to make 15-5.
A 40-metre dash by scrum-half Conor Crilly nearly led to a home try, but a Tobi Ademakin score increased the visitors' advantage, although Ulster deservedly came back with a converted Geoff Harkin score.
Two late tries from replacements Luke O'Leary and Cain Kearney sealed the fate of Ulster, who now travel to Galway on Saturday.
