Australian batsmen have been tormented by two-metre tall West Indians before but the current crop thinks the challenge posed by Sulieman Benn is a unique one.

The towering spinner took five for 155 off 53 overs during the home side's first innings of the second Test at Adelaide Oval and is poised to have an impact in the final two days of the contest.

His contribution helped dismiss Australia for 439, while the 23 run stand late in the day stretched the tourists' lead to 35 runs at stumps.

Baggy Greens batsman Mike Hussey admitted the 28-year-old was difficult to score against.

"It's probably the most unique sort of spinner I've faced in my career really, he does use bounce very, very well obviously with his height," Hussey said.

"I think he's pretty wily with his changes of length and changes of pace as well. Certainly the more you get to face him the more comfortable you feel with it.

"I thought he bowled outstandingly well and he bowled 50 overs which is a huge effort and I think he stuck to his disciplines pretty well throughout that whole 50 overs."

"He was still landing that ball pretty consistently and he was difficult to get away, that's for sure."

Benn says his five-wicket performance has given him a "sense of belonging" and a newfound confidence after putting the hosts under serious pressure.

And the wearing Adelaide Oval track could enhance his input during the home side's second dig.

"It's always nice to know you've got some assistance in the pitch, obviously pitches around the world are really flat now. If you are going to get a pitch that is going to assist you I think you should make full use of it," Benn said.

"I tend to get the ball to bounce on most tracks but obviously because of my height a little spin in the pitch is a bonus for me."

Standing 201cm tall, Benn carries his giant frame like Curtly Ambrose or Courtney Walsh and doesn't mind getting into verbal battles with batsmen.

As such it can be hard to believe that tweakers are his game.

Benn experienced a growth spurt as a teenager but by that stage he was already hooked on the deception and guile of spin bowling.

"I can't say anything attracted me to it; it's just something I started doing from very young, eight or nine years old," he said.

"I never thought about bowling fast, I never had a passion for it, when I started bowling spin I liked it and continued.

"I got tall when I was 14 years old, obviously then you have a crossroads where you want to know what you're supposed to do after that but as I said I had no passion to be a fast bowler."
