An impressive 22-9 victory over Ospreys at the Liberty Stadium saw Leinster move to the top of the Pro12 table.
The Irish side extended their winning streak to seven games, with Dan Biggar's lacklustre kicking costing Ospreys - who were without Rhys Webb due to injury.
Dave Kearney responded to Biggar's opening drop goal with the first try of the night for Leinster, which Jonathan Sexton converted.
Biggar missed a drop goal before trading penalties with Sexton, but the Wales international missed a penalty on the stroke of half-time to leave his side trailing by four points at the interval.
The fly-half scored one of two penalties within 15 minutes of the restart to edge the Welsh region closer, but Noel Reid went over to make Leinster comfortable again.
Although Sexton was unable to convert that time, he was successful when kicking after Kearney put the game beyond reach with his second try four minutes from time.
Marius Goosen's reign at Benetton Treviso got off to a losing start as they were beaten 28-13 by Edinburgh.
The former South Africa fly-half took over as head coach this week following the departure of Umberto Casellato, leaving the Italian side winless in 11 matches this season.
Things did not look set to improve under Goosen with Damien Hoyland scoring a try as Edinburgh took a 10-0 lead after 14 minutes.
James Ambrosini scored two penalties to close the gap to four points at half-time, but Sam Hidalgo-Clyne responded with a pair of successful kicks to restore Edinburgh's advantage with 50 minutes on the clock.
Hidalgo-Clyne converted a penalty try before Luke McLean went over to offer Treviso a glimmer of hope with 15 minutes remaining, but Hoyland crossed for the second time on the night at the death.
