Injury pain but batting gain for Cummins

Pat Cummins has posted his highest Test score of 42, a reward for all the time he spent working on his batting during a series of major injury setbacks.

If there was one upside to Pat Cummins' six years of injury hell it was the chance to improve his batting.

Cummins' name has rarely been mentioned in Australia's seemingly never-ending search for an allrounder, with his express pace viewed as far too important to consider the notion.

But the 24-year-old spelled out his credentials in a vital 66-run partnership with Steve Smith at the Gabba that shifted momentum in the topsy-turvy Ashes opener.

Cummins' knock of 42, the highest of his stop-start Test career, could hardly have come at a more important time given Australia faced a major first innings deficit when came to the crease.

"He's got plenty of power but he has balance. No doubt he could be an allrounder," former skipper Mark Taylor said on the Nine Network.

"I reckon he's good enough to get a Test hundred."

Shane Warne wouldn't go that far but sensed Cummins, who played an ODI as an allrounder earlier this year in New Zealand, would soon be promoted up the order.

The gutsy knock featured a textbook cover drive off Chris Woakes plus a lofted six off Moeen Ali, but also the sort of restraint that Smith craved so dearly.

Cummins made headlines around the world in 2011, when he was 18 and earned man-of-the-match honours on Test debut in South Africa.

A series of serious foot and back injuries meant he didn't play another Test until 2017, with the current match in Brisbane being his first home Test.

The right-armer was often unable to bowl during that stretch, when Cricket Australia managed his body like a fine piece of china.

But batting was a different story, Cummins played some grade cricket as a batsman and spent quality time at the crease.

"I've always enjoyed batting, so every opportunity I have to get a hit in the nets, work with coaches, bat in games, I will do," Cummins said in 2014.

"I've done a lot of work (with NSW coaches) ... we've put an emphasis on the fact that it's also my job to score runs and I need to take a bit more ownership."

The reward was obvious during the most recent Big Bash League season, when he clobbered 134 runs at 33.5 for Sydney Thunder.

"The last probably three or four months I feel I've learnt a lot more about my batting," Cummins said earlier this year.
