TOM Latham collected his second century in three games and Paul Collingwood passed 1,000 championship runs for the season as Durham piled on the runs against Kent.

On the final day of the Specsavers County Championship match at Emirates Riverside they stretched their lead from 156 overnight to 308 at lunch, when they were 297 for five.

In the race to be the first in division two to 1,000 Collingwood was narrowly beaten by Worcestershire's Daryl Mitchell on his way to a match-winning 133 not out against Nottinghamshire.

The lead was 293 when Collingwood departed 20 minutes before lunch for 35, bowled when he went down the pitch to left-arm spinner Imran Qayyum.

Earlier Graham Clark fell for 86, ending a stand of 180 when he skied an attempted pull off Mitch Claydon to mid-off.

Only nine runs were added in the day's first five overs, but 37 came off the next five as Latham pressed the accelerator and survived a sliced drive to Joe Denly at gully off the luckless Adam Milne.

Latham cover drove two fours off his fellow Kiwi in the same over before a bouncer cleared reserve wicketkeeper Adam Rouse for four byes.

He travelled up yesterday to deputise for migraine victim Sam Billings and just failed to grab an edge by Clark off Milne on 71, which arrived at the keeper on the half volley.

A fierce pull for four off the next ball took Clark level with Latham on 75 as he became the chief aggressor. His downfall brought in Collingwood, who got of the mark by lifting Qayyum over long-off for six.

Latham was becalmed in the 90s, tied down by Claydon and spending 21 balls between 93 and 96 before a back-foot four through the covers off the ex-Durham seamer gave him his 13th four and took him to his hundred off 221 balls. He was on 114 at lunch.
