Ryan Harris is in for the long haul with Australia coach Darren Lehmann Australia's Ryan Harris, right, celebrates with teammates after England's Joe Root was caught behind by Brad Haddin. TEST firebrand Ryan Harris believes Darren Lehmann will prove a master mentor and wants to be the Australian coach's trump card for years to come. Harris aggravated a hamstring twinge in a chase to the boundary on the last day of the drawn final Test at The Oval but says a Cricket Australia-enforced, six-week lay-off is purely 'cautious' ahead of this summer's return bout. Harris, 33, should be available for all Queensland's three Sheffield Shield games scheduled before the November 21 Ashes opener at the Gabba and wants to extract every last thunderbolt from his buffeted, 177cm frame. I love playing four-day cricket and Test cricket. I will keep doing it whether that is two, three or five years," revealed Harris, Michael Clarke's strike bowler with 24 English scalps at 19.58 in a 3-0 Ashes series loss. Harris is on the scent of 100 Test wickets. "Until the day I wake up and can't get out of bed or rock up to the ground and think this is too hard I will keep doing it," he said. Former Test batsman Lehmann was given the ultimate "hospital pass" when elevated to unite a fractured Test unit following Mickey Arthur's sacking on Ashes eve. Lehmann could not replicate his instant title magic with Queensland as Australia succumbed to a third consecutive Ashes series defeat. Regardless, Harris insists the new boss galvanised a side that had imploded in a 4-0 Test series loss to India during February and winless Champions Trophy campaign in England. He has taken over, is still finding his feet but the boys love him. He has walked in like he has been there for years and is really enjoying it," said Harris, who was etched on the honour board at Lord's with 5/72 in a second-Test recall against England. I do think he will be good. It is the way he addresses the bad days. He doesn't rant and rave. As long as the guys are learning he is happy. He is big on debriefing after a day's play, having a chat, is honest. That is something he loves and is working well. Harris waits in the outfield.

Harris is uniquely popular with England and Australian fans for his lion-hearted approach and zero histrionics. It was reported that Harris helped Lehmann and pace provocateur Broad smoke the peace pipe but there was no need. Boof being Boof was a bit cheeky. They just had a chat in the rooms and we were having a bit of a laugh about it," said Harris, with a top five world bowling ranking after storming to 71 wickets in just 16 Tests since 2010. I do think the England boys not just Broad will cop a bit here from the crowds this summer, though. Harris said Lehmann, skipper Michael Clarke, bowling coach Ali de Winter, analyst Dene Hills and the bowling group had succeeded in devising the plans to undo England's top order. England skipper Alastair Cook fell to Harris three times while he knocked over No. 3 Jonathan Trott and Joe Root four times apiece with late outswing and killer in-cutters. "We knew Cook obviously after what he did in Australia last time that we if we dried him up we could got him a few times early," said Harris who regularly dragged once impregnable Trott across his stumps. We dried Root up as well and then things went well with Trott and Kevin Pietersen. Ian Bell got away from us but we won't give him as much width next time.
