Tour match, The Waca, day one (close): Western Australia 309-8 v England
Anderson managed to combine swing with a superb economy rate
England had a promising opening day in their two-day tour match at the Waca, restricting Western Australia to 309-8.
James Anderson, who took only 2-303 in the first two Ashes Tests, was the pick of the attack with 3-47 from 23 overs.
Sajid Mahmood found two edges in his second spell, one superbly caught by Chris Read, while Steve Harmison and Monty Panesar also claimed wickets.
WA left-hander Luke Pomersbach hit an unbeaten 90 on his first-class debut, with 10 fours and two sixes.
Anderson found some early movement at the venue for next week's third Test, and a fine away-swinger accounted for David Bandy in the ninth over.
In the next, Harmison should have been rewarded for extracting some pace from a surface widely thought to have slowed in recent years.
But Ashley Giles put down a regulation chance off Chris Rogers, who hit successive fours after his reprieve and went on to make a fluent 66.
More movement from Anderson saw Rogers nibble a catch to Read, giving the Lancastrian figures of 2-19 from 16 overs after his second spell.
His encouragingly economic return should have been even more impressive, but Panesar put down Shaun Marsh on eight at short mid-wicket.

Marsh eventually fell to a spectacular low one-handed diving catch by Read, who retained the gloves with Geraint Jones playing as a specialist batsman, while North gave a more routine chance to Ed Joyce at second slip.
Andrew Strauss captained a flexible England 12 featuring six players from the second Ashes Test debacle in Adelaide.
Skipper Andrew Flintoff, who was hit on the head by Matthew Hoggard in the nets, chose to rest his ankle ahead of next week's Perth Test, but fielded for a short period after his batting scare.
Seamer Liam Plunkett was named in the 12 but did not participate on the opening day because of a dislocated finger.
When Strauss was briefly off the field, Michael Vaughan, in his first match for England since February after knee surgery, directed operations.
Panesar was the more successful spinner, having numerous lbw appeals rejected before he had Luke Ronchi caught at slip.
The slow bowler was earlier convinced he had North caught at slip, and had begun his celebrations only to see that umpire Bruce Bennett had not given the batsman out.
Panesar endured frustration before taking a wicket and a run out
In a display of petulance, he snatched his sweater from the official at the end of the over.
Giles, meanwhile, with 3-262 from the first two Ashes Tests, returned 0-33 from his eight overs.
In his third spell, Harmison collected the wicket his endeavour deserved when he trapped Australia's latest Test squad member Adam Voges with a full-length delivery angling in.
The Western Australia team included several players who turned out for the Chairman's XI in Friday's one-day game at nearby Lilac Hill.
But they were without Test batsman Mike Hussey, who withdrew shortly before the match began.
Despite him being one of his main rivals for a Test place, Mahmood was quick to pay tribute to his Lancashire colleague Anderson.
"I thought he bowled brilliantly," said Mahmood, who took 2-61.
"He put the ball in the right areas and beat the bat quite a lot of time.
"It's good to be in competition with him and the other bowlers because it makes me work that bit harder and makes me want to perform that extra bit more."
