Munster too strong for Castres
Munster were far from convincing as a 26-10 victory over Castres at Thomond Park confirmed them as the first qualifiers for the Heineken Cup quarter-finals.
Johne Murphy's eighth-minute try set the Pool One leaders on their way to a 16-7 half-time lead, with Yannick Caballero hitting back for the French outfit.
Although Castres had nothing but pride to play for, their understrength side ensured a frustrating second half for the home faithful until Wian du Preez touched down with 12 minutes to go.
Unforced errors and missed scoring chances made for a poor display from Munster, who will need to up their game at Northampton in round six as they chase a home draw in the last eight.
