Ciaran Frawley’s 76th-minute penalty ensured Leinster beat a wasteful Connacht 10-0 at the Sportsground. The wet and windy conditions made for a scrappy first half, scrum-half Cormac Foley scoring off an early lineout to give Leinster a seven-point advantage.
Connacht were left to rue their missed opportunities as a break from Player of the Match Josh van der Flier set up replacement Frawley to kick the visitors to their fifth victory of the new season.
Leinster cracked open the home defence inside the first three minutes, Van der Flier breaking off a maul and feeding Foley for a simple finish.
Ross Byrne expertly converted from out wide. Two Niall Murray lineout steals lifted Connacht, as well as his charge-down on Foley, but a subsequent knock-on spoiled their first visit to Leinster 22.
