Test opener Justin Langer says captain Steve Waugh is a "clown" if he doesn't tour the West Indies after leading NSW to a crushing ING Cup final win on Sunday.

The 37-year-old's late season batting blitz catapulted the Blues to their third straight domestic one-day title with a seven-wicket victory over Western Australia at the WACA Ground.

Chasing a modest 208 for victory, the skipper demolished the WA bowling attack, smashing 88 off just 55 balls with 16 fours and a six.

For a man still weighing up his international future it was a massive statement as he guided the Blues to 3-211 off 26.5 overs in 111 minutes.

Carrying a hamstring injury into the match, the elder Waugh twin took up a stand and deliver approach and smashed 18 runs in the 26th over off Brad Williams before being caught behind down the leg side.

Such was the nature of his destructive knock that even a parochial Perth crowd handed Waugh a standing ovation after his innings came to an end.

It even brought a smile to an otherwise downcast WA skipper Langer.

"I'll give you a line about Steve Waugh, if he's not going to the West Indies, he is a clown, he is in the best form of his career," Langer said.

Meanwhile the man himself said he just felt in the groove from the outset.

"From ball one I was seeing the ball really well, I had a good net session yesterday and felt great from the start, some days are like that," he said.
