Acting Australian cricket captain Shane Watson concedes fatigue could be a factor for some members of his team heading into their tour of the West Indies.

The one-day side headed to the West Indies on Friday, just over 12 hours after clinching the tri-series title against Sri Lanka in Adelaide.

Awaiting them is a five-match one-day series crammed into just 10 days, with several players backing up for two Twenty20 internationals in the following five days.

It is the final phase of a packed eight-month schedule which included tours to Sri Lanka, South Africa and the West Indies and a full summer of domestic combat against New Zealand, India and Sri Lanka.

“There’s no doubt there’s some guys that have played the whole summer who are going to be a little bit tired,” Watson said at Sydney Airport on Friday.

“But in the end, that’s part and parcel of playing international cricket.

“You are playing just about all year round, and you’ve got to find ways to be able to freshen up whenever you possibly can and to be able to keep doing everything you can to stay as fresh as you can to be able to perform .”

Apart from dealing with a 5.15am wake-up call on Friday for a flight from Adelaide to Sydney, tiredness isn’t going to be a factor for Watson, who missed most of the international matches due to injury.

“From my perspective, I’m very fresh after missing the majority of the summer so I’m really excited about being able to go and continue to play a lot more cricket,” Watson said.

Watson, who led the team in the last tri-series final, will hold onto the job for at least the early portion of the one-day series in the West Indies, due to a hamstring strain to regular captain Michael Clarke.

“I’ve really enjoyed the captaincy,” Watson said.
