It was a tight, tense affair and the Lions played some good rugby but the Springboks prevailed thanks to two late penalties from replacement stand-off Morne Steyn.
The world champions came back from losing the opening match to win the series by two Tests to one.
Here’s how the Lions rated:

2. Ken Owens
Marked his first Lions Test start with a try. The hooker added more assurance at the lineout. 7/10 Photo: David Rogers/Getty Images
