Darren Lehmann has mixed feelings about becoming the greatest run-scorer in Australian domestic cricket.

While the record marks an outstanding achievement, it also illustrates the fact the South Australian captain and dual domestic cricketer of the year has not represented his country as often as he would have liked.

Poised to pass former SA skipper Jamie Siddons' record of 10,643 runs in the domestic four-day competition, Lehmann has a typically laconic attitude towards the milestone.

"It's nothing that really worries me, if it's next week or the week after, whenever it is, it's just one of those things that happens," Lehmann said.

"It's a pat on the back and obviously it's a personal achievement to overtake such a great player like Jamie.

"We've spoken about it, him and I, over the last couple of days and I'd be very happy to do it if it happens.

"But it would be nice to have had more Test cricket and one-day cricket but that's they way it goes. I can't complain, I'm having a good time playing cricket still and I'm enjoying every moment."

Lehmann enters the Pura Cup match against Western Australia in Adelaide starting Sunday needing just 43 runs to pass Siddons' mark.

The exciting left-hander raced towards the total with a blazing 246 from 238 balls against Tasmania earlier this month.

"It will be great when it comes along and I'm looking forward to it," he said. "I'll just enjoy the moment when it happens and then move on, put it in the past and away we go again."

With two young children and twins due this summer, the recently named captain of English county side Yorkshire said family commitments would feature in any decision on his future.

But after Australian captain Steve Waugh's revelation last week he wants to continue playing to late 2004, 31-year-old Lehmann indicated he had plenty of cricket ahead of him domestically and overseas.

"Four kids is going to make it hard work to keep travelling away all the time so I'll have to look at that and see what happens but at the moment there's no problems playing all year round," he said.

"I've definitely got a three-year plan in mind at the moment and that's as far as I'm looking ahead.

"Come the end of those three years I'll look again. The next three years is just full-on cricket and I'll enjoy every moment."
