MITCHELL Starc is built for speed but this year the Australian fast bowler has been asked to turn endurance athlete.
The man accused by Shane Warne of having soft body language last summer has featured in every international played this year across all three forms. 
His 23 matches far exceeds the workload of the other quicks. Starc is the only frontline Australian paceman backing up after the Ashes for this limited-overs series, yet it's understood he is also pencilled in for the   October Test tour of Bangladesh, which Mitchell Johnson and Josh Hazlewood could be rested from.
By the end of   December, Australia will have played 35 internationals and, even if Starc is rested from the odd one-dayer, he is still on track to battle through more Test matches than any fast bowler in recent history - with home series against New Zealand and the West Indies to come.
In 2010, Johnson played 36 matches, and 11 of those were Tests. Starc has already played eight Tests this calendar year and could get through a whopping 15 by Boxing Day if his body holds up.
The 25-year-old was Australia's leading wicket-taker in the World Cup, the Ashes and the 2014 World Twenty20 - making him the nation's most valuable bowling commodity.
But with the international schedule relentless for the next 12 months, selectors face a conundrum over whether to continue playing their No.1 strike weapon at every opportunity or find a period to rest him up so as not to burn him out. Starc picked up a niggle in his ankle during the Ashes and has extensive strapping on his right knee, but he he won't be asking for a spell - he'll leave his management up to selectors and medical staff.
"There's a lot of cricket this summer especially, it's pretty much non-stop until the end of   March," Starc said."As I have done the last few months, I'll monitor my body and make sure I'm 100 per cent ready to go for every game that I can."
