Purple rucksack

LUNCH: Warwickshire 428 for 9 (137 overs). Clarke 52, Rankin 1.

Clarke reached 50 from 63 balls with seven fours and one six. Since returning from a broken hand he has batted 12 times in the championship, failed to reach 20 only twice and scored five 50s.

His intelligent manipulation of the strike added another 15 runs for the last wicket in the last two overs before lunch to increase the lead to an imposing 174.

People playing on the outfield. Man with purple rucksack studying the pitch. Allan Donald, on his last first-class assignment with Warwickshire, striding purposefully across the field.
