3- vs Sri Lanka, April 2012 - 151, England won by eight wickets
Pietersen had begun his most turbulent year with a miserable run of scores, along with most of his team-mates, in a 3-0 drubbing against Pakistan in the United Arab Emirates.
Here, in searing and stamina-sapping heat, he dominated the Sri Lankans on their home turf to lead England to a series-levelling and face-saving victory.
