Pietersen lined up for Surrey against former side Hampshire in the Clydesdale Bank 40, his first outing since being left out of England's third Investec Test against South Africa at Lord's.
Pietersen has shown a weakness against slow left-armers in the past and it was to prove his undoing once more as he was bowled pushing forward to Liam Dawson off his first delivery.
A great cheer rang around the ground following the dismissal, although that may have had more to do with his acrimonious departure from Hampshire in 2010.
Pietersen has been involved in a stand-off with the England and Wales Cricket Board. He initially retired from limited-overs cricket and hinted at quitting the Test arena too before performing a U-turn and announcing he wanted to play in all formats for his adopted country.
However, he still faces questions over text messages he sent to members of the South African team during the second Test at Headingley.
It was reported on Sunday one of the texts described England captain Andrew Strauss in offensive terms and that he also offered advice to the South Africans on how to dismiss the skipper.
Press Association Sport understands Pietersen and Strauss will meet following the conclusion of the third Test at Lord's.
