Yashasvi Jaiswal, all of 21, oozes maturity in his method and approach at the crease. He says that he is never unsure of his decisions while batting and that the clarity of the Indian team management's expectations of him have helped.

The opener played a boundary-laden 25-ball 53 against Australia in the second T20I on Sunday. He shared 77 runs with fellow opener Ruturaj Gaikwad (58) before getting out in the sixth over. But the platform laid by him helped India post a mammoth 235/4.

"It was really special for me. I was trying to play all my shots, be fearless, take bowlers on. I was fully sure with my decisions," Jaiswal said after the match.

"I have been told by (captain) Surya (Kumar Yadav) and (coach) VVS (Laxman) bhai to express myself. I always think of how I can improve myself around experienced players and nothing else. Still learning."

Jaiswal, who was named player-of-the-match, said he was working on improving his fitness level as well as mental strength.

"I really worked on my fitness and shots. I feel the mental stuff is more important at this level. I try to get better each and every day," said the youngster.

Jaiswal has played two Tests and 10 T20Is so far in his career.

Asked about his mix-up with Gaikwad in the first T20I in Visakhapatnam, which led to the latter's run-out, Jaiswal said: "It was my mistake. I went to him and said sorry. (Marcus) Stoinis was between me, I was sure but then not sure. I made the wrong call.

"I accepted that it was a mistake and it happens. Rutubhai was humble and said in the gym that next time we are running, we will take secure singles."

If Jaiswal has been providing India with great starts, Rinku Singh has been finishing off games smartly. A left-hander like Jaiswal, Rinku too is enjoying his game.

"I bat at this number (No. 5) a lot so I am calm knowing this position. I like to play each ball according to where it lands. I try to notice whether it's a slower ball or a faster ball, and I respond accordingly.

"I am enjoying with everyone. Feeling good," said Rinku.

Rinku said he practises knowing well that he wouldn't get much time to bat. "I know I'll get 5-6 overs sometimes or maybe 2 overs... That's exactly how I practice. As if I'm batting in the last five. That's how VVS Sir has also told me to play in the nets," he said.
