THE highs and lows of Durham cricket were encapsulated on Saturday by Liam Plunkett's five-wicket haul and Ian Pattison's cruel injury.

The incredible injury jinx continued when Pattison suffered similar damage to Paul Collingwood, falling down in his follow through while bowling and dislocating his shoulder.

As with Collingwood, who hopes to be back in early August, there is cartilage damage and just when he was starting to look the part Pattison is out for at least two months.

He was in the sixth over of a tidy spell of medium pace which had earned him one for seven, the wicket coming when Scott Richardson edged a drive into his stumps.

It broke a second wicket stand of 66 with Yuvraj Singh, whose powerful driving was largely responsible for Plunkett conceding 29 runs in his opening four-over spell.

But after Pattison struck and Dewald Pretorius had Singh caught behind for 56, Plunkett returned at the Kirkstall Lane end and had four wickets in nine balls during a spell of five for 24 in eight overs.

He is the third Durham bowler to take five wickets on his championship debut after John Wood and James Brinkley, the difference being that he can be confidently tipped to go on to repeat the feat many times.

Less than two months after his 18th birthday, Plunkett made a huge impression but refused to get carried away.

"I'm glad I did it, but I'm not too excited because I know I might not take a wicket in the second innings," he said.

"I felt nervous and probably tried too hard in my first spell, when I couldn't find a line. The switch of ends didn't help because I struggled with my run-up at first, but I just tried to bowl a good line and shape the ball away from the batsmen.

"I thought I had a decent tour of Australia with the Under 19s and I just hoped to get a couple of games for Durham at the end of the season. To get my chance so early is brilliant."

Encouraged by his father, Alan, who bowled for Marske, Plunkett played for Middlesbrough in his early teens and was spotted by Durham's Director of Cricket, Geoff Cook. "I came to Yorkshire's indoor nets a few times but they didn't pursue it," he said. "I was batting at No 3 at the time, but Geoff must have seen something in my bowling."

Plunkett, who went to Nunthorpe School, remains eligible for England Under 19s until next summer. He played in three Tests last season against India and after two more against South Africa this summer he can be released from Under 19 duties if Durham require him for championship cricket.

On the strength of Saturday's showing he could soon become a fixture in the side. He achieved good pace and moved the perfect ball away from Richard Blakey to have him well caught by Phil Mustard for his first wicket.

Then Gary Fellows sliced to gully and Richard Dawson edged the next ball to second slip. The hat-trick ball was a full toss to Darren Gough, who went for such a big drive two overs later that the edge carried all the way into Pretorius's hands at third man.

Plunkett completed his haul by yorking Chris Silverwood and it was surprising that he wasn't called on again as Yorkshire recovered from 115 for eight through an excellent 132-ball century from Michael Lumb. With Pattison out of the attack and Neil Killeen and Nicky Phillips both bowling poorly, it was left to Pretorius to end a ninth wicket stand of 79 by removing Pieter Swanepoel.

Phillips continually fed left-hander Lumb's leg-side strength and he had scored 105 out of 154 since coming to the wicket when he tried to smash Phillips for his 17th four and was bowled.
