Leinster topple unbeaten Scarlets at the RDS Arena
Leinster 19-15 Scarlets
Leinster ended Scarlets' 100% record following a deserved 19-15 triumph at the RDS Arena in the Guinness Pro12.
Tries from centres Hadleigh Parkes and Gareth Owen helped give the Welsh region a 15-9 advantage at the interval.
Ian Madigan kicked three penalties for the Leinster before the break to keep them in contention and they went ahead in the second period through Mike Ross' converted touchdown. Madigan then added another from the tee as Leinster secured the victory.
Leo Cullen named a number of his Ireland internationals in the team to face the side residing at the top of the table, but it had little effect early on as the visitors started the brighter and, after a period of pressure close to the hosts' line, the burly Parkes barged over from close range.
Leinster did hit back, putting together a lengthy drive which resulted in Jake Ball being sin-binned, but a penalty from Madigan was all they could accrue while the lock was off the field.
After Ball returned, the Dublin-based outfit's fly-half added his second from the tee before the Scarlets crossed the whitewash again through Owen.
Although Madigan kicked another three-pointer, Dan Jones was also successful with the boot as Wayne Pivac's team went into the break 15-9 ahead.
The Irish side were second best in the first half but they opened the final 40 minutes on the front foot and Ross' score was the reward for their endeavour.
Leinster were now firmly on top and a penalty from Madigan gave the Irish province a four-point buffer with a quarter of the match remaining.
In-form Connacht moved to the top of the Guinness PRO12 table with a three-try 33-19 victory over Benetton Treviso at the Sportsground.
