Kevin Pietersen put England in firm control of the second Test against Sri Lanka with a sparkling 151.
He shrugged off a warning for time-wasting, after attempting a switch-hit, to hit the highest score by an Englishman in Sri Lanka.
Alastair Cook and Jonathan Trott gave Pietersen the platform to blast the tourists into a 185-run lead with scores of 94 and 64 respectively.
Sri Lanka had to face the final over of the day, which they saw out unscathed.
As dominant as England's batting performance was, Pietersen's warning became the biggest talking point of the day.
He had already used the switch-hit to score one boundary when he got into position to do it again later in his innings, only to see bowler Tillakaratne Dilshan refuse to deliver the ball.
Umpires Asad Rauf and Bruce Oxenford warned Pietersen for time-wasting, to re-open the argument regarding the legitimacy of the shot, but it failed to knock the Surrey star from his stride.
