Second-half tries from wingers Adam Byrne and Barry Daly helped Leinster to a convincing 24-13 win over Connacht at the RDS and send them to the top of the Guinness Pro12.
A injury-time consolation score from Connacht's Shane Delahunt put a better gloss on the scoreline, but Leo Cullen's side were full value for the win and sit joint-top with the Ospreys and Glasgow Warriors on 26 points.
Connacht enetered the game on the back of four successive wins in all competitions and made the early inroads on the scoreboard.
Craig Ronaldson slotted over two early penalty attempts before Isa Nacewa continued where he left off in Montpellier with Leinster’s first three-pointer in the 23rd minute.
Seán O’Brien’s recent return to competitive action came to a premature end in the 27th minute when referee John Lacey deemed the flanker had led illegally with a shoulder charge on Connacht centre Peter Robb and showed the Tullow man a yellow card.
While Pat Lam’s side had the numerical advantage, it was Leinster who added two penalties during the 10-minute spell, which also saw Robb himself yellow carded for a deliberate knock-on.
O’Brien returned shortly before the interval as a crowd of 18,200 in the capital cheered the hosts off with a 9-6 lead.
Winger Adam Byrne claimed the game's opening try in his first Leinster appearance of the season as the home side's pressure eventually paid off.
Joey Carbery drew in the cover and Jamison Gibson-Park's quick pass to Seán Cronin allowed the hooker deliver an admittedly ugly pass to Byrne who slid over in the right corner, with Nacewa adding the extras.
Ten minutes later and the lead was out to 11 points as Connacht struggled to get their hands on the ball.
In truth, the visitors never looked like closing the gap and Barry Daly sealed the win with five minutes remaining of his first ever Leinster start. Carbery's perfectly weighted pass allowed the winger to brush off the challenge of Kieran Marmion to dot down.
Substitute hooker Delahunt grabbed a late try with the clock in the red but it was Leinster's night as Connacht's search for a first win at the RDS continues for at least another season.
