|Close, day two: Durham 62-3 v Warwickshire 472|
|Durham 2 pt, Warwickshire 5 pts|
Teenager Sam Hain claimed the second County Championship century of his career to boost Warwickshire on day two at the Chester-le-Street.
Hain formed an effective partnership of 101 with Rikki Clarke (54), who fell to fast bowler John Hastings (5-94).
But the 18-year-old reached a total of 109 as he powered Warwickshire to a finish of 472 on day two.
In reply, Durham suffered a slow start with Chris Wright dismissing Mark Stoneman for five as they reached 62-3.
Durham opener Keaton Jennings (12) and Michael Richardson (2) both fell to Keith Barker (2-22), with the hosts trailing by 410 runs.
Hain, who celebrates his 19th birthday on Wednesday, has now recorded a second century in his debut season.
His first came against Northamptonshire earlier this season, which made him the youngest player ever to score a first-class century for the Bears.
Durham captain Paul Collingwood:
"Sam Hain showed great concentration. We tested him with all sorts, but he came through it.
"He's a bit like Jonathan Trott with some of his mannerisms.
"It was a tricky decision whether to take the new ball in the morning. The old ball was giving us some reverse swing but when we did take the new one nothing happened."
BBC Newcastle's Martin Emmerson:
"For the second week in a row Durham have seen their opponents take maximum batting points after putting them in. Although Paul Collingwood says this is a completely different wicket to last week's at Headingley, the outcome has been more or less the same.
"Warwickshire made 472 - their highest score in Chester-le-Street - and again Durham are up against it as they try to rescue the game.
"They need to make 323 to avoid the follow-on, but with their first three batsmen back in the pavilion inside 17 overs that will be tough to reach, unless they can show some grit and determination.
"There are 17-year-olds who haven't seen Warwickshire win here, such has been their poor run of form in the north east, with seven defeats and two draws from their last nine visits. But they must fancy their chances of a rare victory now, with Durham 62-3 at the close of day two and still 410 behind."
