Nathan Lyon hailed fellow Australia spinner Adam Zampa after his team's win over West Indies on Sunday.
Lyon (3-39), Zampa (3-16) and Glenn Maxwell (1-3) spun Australia to a convincing six-wicket victory in their tri-series opener in Guyana.
The trio helped dismiss the hosts for 116 before an unbeaten 55 from David Warner saw Australia complete their chase with 146 balls to spare.
Lyon was thrilled with the performance of Zampa, the 24-year-old who finished with his best international figures.
"He played his role exceptionally," he told a news conference.
"The way he goes about his cricket, even in training, he's always trying to get better.
"It's exciting for a young leg-spinner to come out and show his skills to the world on the big stage and on a turning pitch, it was pretty exciting."
Warner made a run-a-ball 55 in the chase as Australia finished at 117-4 to cruise to victory.
Lyon was full of praise for the explosive opener and said the left-hander made what could have been a tricky chase look easy.
"I thought David was in exceptional form. We've seen the highlights and the results in the IPL [Indian Premier League]," he said.
"He's a world-class player and proven that tonight.
"To chase little totals can be difficult, but the way he went about it and the style of cricket he played, I thought he was exceptional."
