The Australian paceman has dismissed Pietersen for the ninth time in Tests, bowling him for 53 on Sunday in the second Ashes battle.
Siddle also claimed Pietersen in the first innings in Adelaide.
Pietersen has played against Siddle in 14 Tests and fallen to the Victorian more times than any other bowler in his Test career.
And in the times he's been out to Siddle, Pietersen has averaged just 28.22 in those innings.
The next best bowlers in taking the wicket of the South African-born strokeplayer are Brett Lee and Muttiah Muralidaran, who each dismissed Pietersen six times in Tests.
For the record, Australian great Shane Warne's toying with South African batsman Daryl Cullinan has gone down in folklore.
Warne dismissed Cullinan four times in seven Test meetings, and the Australian legspinner claimed the Proteas batsman eight more times in one-day internationals.
