Munster's Pool 2 rivals Toulon came out on top over Bath in an entertaining nine-try contest and took a 45-34 victory in the Investec Champions Cup at Stade Mayol.
The result means all six teams in the group have a win and a loss to their name after their first two matches but Bath's bonus point means they top the table with six points, with the other sides on five.
Clayton McMillan's Munster side opened their account with a 31-3 victory over Gloucester on Saturday evening.
In France, Finn Russell slotted two penalties either side of Brian Alainu’uese’s try which gave Toulon a 7-6 lead.
Mateo Garcia kicked three points for the hosts following a ruck infringement but Bath went ahead through Ted Hill with their first try of the game before Garcia knocked over his second penalty to make it 13-13.
Toulon went eight points to the good when Juan Ignacio Brex finished off after Kyle Sinckler’s powerful run, that was before Garcia kicked his third penalty of the game – but back came Bath again when Russell’s delayed pass allowed Santi Carreras to cross the whitewash.
Sinckler’s powerful run proved troublesome again in Toulon’s next try as Gael Drean picked a line to race clear and re-establish the French side’s eight point lead but Bath were not going away themselves, Arthur Green dotted down to bring the deficit back to one.
Toulon got their try bonus point through Lewis Ludlam but Max Ojomoh’s short pass let Louie Hennessey cut the gap to four points for Bath before another penalty and Teddy Baubigny’s try finished things off in the French side’s favour.
Elsewhere, Edinburgh were brought back down to earth as they fell to a 33-0 defeat at Castres (above).
The visitors claimed a stunning win over Toulon on their return to the competition last week but they were well beaten in France this time.
Christian Ambadiang's 12th-minute try was the only score of the first half, but the lead extended to 12-0 – six minutes into the second period – when Loris Zarantonello crossed and Pierre Popelin converted.
Tyler Ardron was the third Castres player to score a try as they stretched their advantage even further and Edinburgh’s cause was not helped when Piers O’Conor was shown a yellow card for a dangerous tackle.
Castres took full advantage, Adam Vargas securing the bonus point with the hosts’ fourth try when he crossed in the corner.
And the scoring was complete in the 63rd minute when Popelin sent over his fourth conversion following Vilimoni Botitu’s try.
Meanwhile, in Leinster's Pool 3, Marcus Smith pulled the strings as Harlequins registered the first victory of the campaign by overwhelming Bayonne 68-14 at The Stoop.
Quins made an error-strewn start, but their England playmaker took control by setting up their opening two tries with pinpoint kicks and from there it was one-way traffic, with the visiting whitewash breached 10 times.
Smith, restored at fly-half after sitting out the 45-28 defeat at Leinster, was named man of the match for a performance that was full of clever touches and included nine conversions.
Will Porter, Sam Riley and Kieran Treadwell each ran in two tries on a grim afternoon for Bayonne, who had already folded by half-time.
Yesterday, a weakened La Rochelle side fell to a 42-21 loss to table-toppers Stormers.
