The left-arm orthodox spinner and left-arm 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 46.5 and 15 wickets with the ball at an impressive 29.8.
He was superb in WA's remarkable Shield win at the WACA against Tasmania that finished Sunday when the Warriors successfully chased down 357 to win by two wickets to 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 his 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 also hopes that 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.
"I had a long session with Luke Towers about trying to relax because if you have a relaxed body you can actually move. Ashton is so relaxed when he bowls as well that he can get flight and he is just so fluid.
"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."
Meanwhile, Tasmanian captain George Bailey was obviously disappointed to lose at the WACA after dominating most of the match.
It ends the Tigers' chances of making the Shield final, but Bailey was more disappointed with the WACA pitch that was so much easier to bat on for WA's second innings than at any other point in the first two days.
"I wasn’t happy with it, but I do understand how hard it can be to create a wicket if you get two or three days that are 39 degrees," Bailey said.
"Personally, the WACA that I would like to see is one where I would like the cracks to come into the play on day three and four, and a bit more turn and for it to break up a little more rather than having it like it was on day one.
"It was a big advantage for Western Australia to win the toss and even getting knocked over as quickly as they did in their first innings was a bit of a blessing in disguise because we had to bat again when it was still at its best for the bowlers.
"There was no doubt yesterday and today was going to be best to bat on."
