Stand-in coach VVS Laxman praised the growing maturity of Vaibhav Sooryavanshi, after the 15-year-old's 81 off 49 balls helped India complete a Twenty20 series sweep against Zimbabwe.

Sooryavanshi's second half-century in four days steered India to 192/5 before Zimbabwe were restricted to 157/7 to complete a 3-0 series win on Sunday.

"Very mature. And that's what I really appreciate about Vaibhav," said Laxman.

Sooryavanshi tempered his natural attacking instincts in an innings containing eight fours and four sixes on a sluggish surface.
