Second Test, Headingley, day one (close):
England 366-5 v West Indies
Vaughan's century was met enthusaistically by Pietersen
Captain Michael Vaughan returned with a stylish 103 as England posted 366-5 on the opening day of the second Test against West Indies at Headingley.
In his first Test for 18 months because of injury, Vaughan hit some classical strokes to record his 16th century.
He shared a commanding 131 in 27 overs with Kevin Pietersen, who survived a stumping off a no-ball when 20 to record his second successive hundred.
Pietersen struck 15 boundaries and was undefeated on 130 at stumps.
Vaughan's first success was to win the toss and he chose to bat on a flat-looking surface when he was satisfied that early cloud had given way to sunshine.
England recalled seamer Ryan Sidebottom after a six-year gap, while West Indies were without injured Shiv Chanderpaul.
Andrew Strauss might have gone first ball when he fended a short ball from Daren Powell uppishly but Daren Ganga at deep short-leg could not gather diving forward.
Vaughan played some classical strokes on his home ground
Strauss struck two trademark square cuts but, attempting another one at a wide delivery from Powell, got a bottom edge and was caught behind.
Vaughan took 34 balls to record his first boundary, swivelling to pull Powell through mid-wicket.
Contrasting, consecutive boundaries came off Jerome Taylor, a thick edge through the gully followed by a sumptuous off-drive as the captain began to find his touch.
Alastair Cook, who has yet to score a duck in Test cricket and has been dismissed in single figures only five times in 28 innings, was progressing comfortably until Chris Gayle, given the almost customary pre-lunch over of spin, trapped him lbw for 42.
Umpire Asad Rauf continued his policy of giving spinners decisions that often used to be denied them when he gave Cook out propping forward.
After lunch, Vaughan and Pietersen accelerated with some fluent strokes.
The captain was gifted the single he needed to reach fifty when counterpart Ramnaresh Sarwan fumbled at mid-off, one of several fielding blemishes that again tarnished the West Indian performance.
Pietersen dominated the West Indies attack once again
When Gayle returned for his second over there was more action, Pietersen reprieved when the slow bowler over-stepped.
Pietersen might well have heard the call as he sauntered way down the wicket and casually returned to his crease when the stumps were broken.
It was one of the few times he failed to make contact as England's most attractive strokeplayers required only 43 balls to take England from 150 to 200, Vaughan proving his fitness by picking off a series of twos.
As the confidence of the tourists drained, and the field spread to leave just a solitary slip, Pietersen notched his fifty from 67 balls with his sixth four, even a mis-hit having enough force to reach the long-on boundary.
There were signs of fatigue from the captain towards the end of the afternoon session, with a loose play and miss at a wide one from Taylor followed by a speculative prod at a slower one that sailed through the slip cordon.
Vaughan reached three figures with one of few unconvincing strokes, a thick edge sailing through the vacant slip area for four.
The landmark was warmly greeted by the partisan crowd and Pietersen risked further alarm for England's injury-jinxed captain by lifting him off the ground in an exuberant bear hug.
Shortly afterwards Vaughan's accomplished innings ended when another well struck pull was smartly pouched on the mid-wicket fence.
Bouncers were used sparingly but Paul Collingwood received a good one on nought from Taylor second ball which he fended just wide of slip.
He also edged through the slips and was dropped at first slip by Gayle, who later atoned with a low catch to dismiss the all-rounder for a sketchy 29.
By that stage West Indian misery had been compounded when Sarwan fell awkwardly on the rope attempting to cut off a boundary and had to be led from the field with his right arm precariously encased in his sweater.
But with Ganga taking the reins they were rewarded for their perserverence with late wickets, even though a slow over rate will result in a financial penalty.
Finding some movement with the old ball, Corey Collymore produced a fine delivery to catch Ian Bell's edge but it could not take the gloss from England's day.
