Western Australian coach Justin Langer likened 19-year-old all-rounder Ashton Agar to some West Indian greats as he continues to marvel at his remarkable performances with bat and ball.

The left-arm orthodox spinner and left-handed lower-order batsman only made his Sheffield Shield debut late last month, but already has two half-centuries to his credit with the bat at an average of 46.5 and 15 wickets with the ball at 29.8.

He was superb in WA’s remarkable Shield win at the WACA Ground against Tasmania that finished on Sunday when the Warriors successfully chased down 357 to win by two wickets and remain a chance to qualify for next month’s final.

Agar also claimed 3-47 and 1-52, but it was his unbeaten 71 that was a match-winning performance along with 83 from Sam Whiteman late on the third day.

Langer has never doubted Agar’s ability with bat and ball from the moment he laid eyes on him.

“Ever since I threw balls to him the first time I saw him I thought he’s got extraordinary talent with the bat,” Langer said.

“He’s so loose and is like an old-fashioned player. He is actually like one of the old West Indian players like Roy Fredericks or Clive Lloyd and those guys who were so loose in their hands and so relaxed.”

Langer now hopes fellow WA youngsters Marcus Harris, Luke Towers, John Rogers and others can follow in Agar’s footsteps.

“He is actually a great example to all our other young guys because blokes want it so much and they are so tense,” Langer said.

“It’s the same when he bats and all the great sportsmen whether it’s Roger Federer or Usain Bolt, they are always so loose and that’s how he is. He’s got great competitive instincts as well and that’s why he’s got such a bright future.”
