(CNN) -- The British and Irish Lions swept aside an understrength kwaZulu-Natal Sharks 39-3 in Durban on Wednesday to maintain their unbeaten record in South Africa.
Jamie Heaslip goes over for the British Lions' final try in their victory over the Sharks on Wednesday.
Their fourth win came after a lackluster first half in which they held a 7-3 lead before romping home after the halftime break.
The Sharks were missing the core of their team who have been called up by the Springboks to prepare for the three-Test series against the Lions.
A converted first half try by hooker Lee Mears set the Lions on their way, with scrum-half Mike Phillips, wing Luke Fitzgerald, full-back Lee Byrne and number eight Jamie Heaslip going over after the break.
Irish flyhalf Ronan O'Gara scored 12 points with James Hook adding a late conversion to seal an emphatic success.
"I think a lot of things came together," captain Paul O'Connell told Sky Sports.
"One of the biggest things is the defense, we've got four defensive systems trying to come together and play under one system and it came together well today.
"They had a lot of the ball there at the end and everyone looked very comfortable defending together."
The Super 14 side kept in touch during the first half with a Rory Kockott penalty, but ran out of steam after the break on a breezy evening in ABSA Stadium aside the Indian Ocean.
The Lions play Western Province in Cape Town on Saturday before returning on the following weekend to Durban for the first Test against world champions South Africa.
