Tour match, Colombo (day two, stumps): Sri Lanka Board XI 298-9d & 77-8 v England 134
Vaughan looks back in horror to find he has been bowled
Matthew Hoggard took 5-25 after England had been bowled out for just 134 in the match against the Sri Lanka Cricket President's XI in Colombo.
Ravi Bopara boosted his claims for a Test debut this Saturday by top-scoring with 47, and the Essex youngster then had to take the new ball with Hoggard.
England were two bowlers light in the absence of seamers James Anderson (ankle) and Steve Harmison (back).
But Hoggard did the work of three men as the hosts reached stumps on 77-8.
The President's XI declared on their overnight score of 298-9 and left-arm seamer Sujeewa de Silva soon beat a defensive push from Michael Vaughan to clip the stumps.
He then ended the charmed but short innings of Ian Bell, who was dropped at slip and then caught off a no-ball, by finding the inside edge on the way through to wicket-keeper Kaushal Silva.
When the other left-arm seamer, Chanaka Welegedara, had Pietersen caught behind in the next over, the seventh of the innings, England were 21-3.
Alastair Cook had provided the bulk of that total and he clipped de Silva handsomely through the on-side for two boundaries as he looked to press on.
But he was lbw on the sweep to leg-spinner Kaushal Lokuarachchi just before lunch, falling for 35.
Owais Shah needed 34 balls to get off the mark, eventually making 26 before he was bowled aiming a loose drive at the third seamer, Ishara Amerasinghe.
Bopara, batting one place below Shah at six, survived a confident lbw shout second ball to prosper after lunch by working the ball into gaps.
But he was forced to change the pace of his innings as the lower order became exposed.
Matt Prior (10) was caught at slip off medium-pacer Chamara Kapugedera and Hoggard was castled by De Silva, angling the ball in from around the wicket.
Bopara proved to be the most successful of the batsmen
Having flashed a pull and a drive to the boundary in response to the sudden clatter of wickets, Bopara picked out extra-cover with another attacking stroke to give De Silva his fourth wicket.
The innings was wrapped up when Anderson was yorked by Welegedara.
Harmison received treatment throughout the morning and went swimming after lunch in a bid to loosen his stiff lower back, after pulling up in mid-over on Sunday.
But he was in no shape to bat, and could not bowl either.
It was then revealed Anderson had injured his ankle during practice between the innings, so Bopara had to bowl the second over.
The unlikely new-ball attack of Hoggard and Bopara proved to be an inspired pairing, however.
Hoggard swiftly removed four batsmen with Test experience, plus Silva, while Bopara chipped in with the wickets of top-scorer Mahela Udawatte (45) and number three Malinda Warnapura.
Cook added another wicket by running out De Silva, and the hosts were clinging on when bad light ended play early, though they did hold a more than useful lead of 241.
When the chips are down you've got to pull the team together but as a whole we are very positive and very upbeat
Hoggard, who has started in just two of England's eight Tests this calendar year because of injury problems, will arrive in Kandy in excellent form.
Finding swing, the Yorkshireman bowled the left-handed Upul Tharanga before taking three more wickets in four deliveries.
Tillakaratne Dilshan flashed low to second slip, Jehan Mubarak padded up to one which shaped back and Kapugedera sliced his first ball to gully.
After the day's play he said: "It was nice to pick up the wickets, but I didnt do much different than in the first innings.
"Thankfully they nicked it a bit more often than they did in the first innings - sometimes shape is better than swinging it around corners.
"When the chips are down you've got to pull the team together but I think the team as a whole are very positive and very upbeat.
"Hopefully we can pile on the runs tomorrow.
"The Sri Lanka bowlers bowled well, they put in a performance and it's a different game when you lose a few wickets and come under pressure."
