David Wiese's tenth first-class century, in an unbroken stand of 153 with captain Ben Brown, took Sussex to a first-innings lead over Warwickshire on the final morning of their rain-ruined Specsavers County Championship match.

In reply to the home side's 299, Sussex went into lunch on 347-7 at Edgbaston with Wiese on 103 (93 balls, 14 fours, three sixes) and Brown on 90 (171 balls, eight fours).

After Sussex resumed this morning on 194-6, Ollie Robinson soon edged Keith Barker behind to give wicketkeeper Tim Ambrose his fifth catch of the innings.

But Brown, in his first knock as Sussex skipper, barely played a false shot while Wiese was more aggressive, clearing the ropes three times on his way to a 91-ball century.
