Birmingham: Warwickshire captain Ian Westwood won the toss and chose to field against England in the Ashes warm-up match at Edgbaston on Wednesday.
This three-day game was designed to give England first-class match practice ahead of next week's Ashes opener against Australia at Cardiff.
England captain Andrew Strauss led what was the probable first Test side although left-arm spinner Monty Panesar was under pressure for his place.
Meanwhile across the Midlands players on the fringes of the Test team were pushing for a place as the England Lions took on Australia in a four-day contest at Worcester.
