Suryakumar Yadav is only five-innings-old in international cricket. You wouldn't know that, looking at him bat in any of those games. He's looked nerve-less, decisive and crisp in his stroke-play, calm and confident in his batting.

Having made his debut when already past 30 has meant, perhaps, that Yadav might not have the same length of international cricket to look forward to that the Prithvi Shaws and Ishan Kishans have, but it's also meant he's come into international cricket with a greater understanding of his game. He made an immediate impact in the T20Is against England in March, and given a go in the ODI side, he's returned a Player-of-the-Series performance against Sri Lanka.

India lost the third one-dayer, but took the series 2-1, and Yadav played a key hand in each of the three games. Starting out in his career, Yadav has got the fine balance of soaking it all in after years of waiting for it, versus the hunger because of a wait that lasted as long as it did.

"Obviously, everyone dreams of playing for India. It has been a lot of effort, lot of grind, lot of patience behind this," Yadav said after the third ODI against Sri Lanka. "It has been worth the wait, and I'm really happy about it. From here on, how I build it is all in my hands. I'm really excited for the journey ahead."

Yadav had always been a batter with plenty of sparkle. But he pinpointed returning to Mumbai Indians in 2018 as the turning point, after which his game has gone to a new level. It's borne out by the numbers too. Since the 2018-19 season, Yadav has averaged 55.56 in List A cricket, at a strike rate of 131.88. In T20 cricket, his average has been 37.60 at a strike rate of 147.30.

"I've always been batting the same way as I am now," Yadav said. "But yes, after I came to Mumbai Indians in 2018, things started changing a bit. I got to know what my responsibility is, how do I go about my game, how can I take it one step ahead. That's when I started practicing even more. Talked to all the players who knew me really well from the last five-six years."

Yadav's scores in the ODIs, 31*, 53, and 40 - all scored at better than a run-a-ball - point to how quickly he got into the groove, although he did express disappointment at not carrying on in the second and third games. He was looking in command during the second game, steering India's chase after half the side had been out, when one moment of indecision meant he was trapped in front. While India won that match on the back of Deepak Chahar's heroics with the bat, Yadav's fall in the third ODI - he was once again the key wicket - meant there was no similar recovery.

"I'm disappointed about that," Yadav said. "The way I started in the first game, I got good confidence. In the second game, it was the perfect situation to win a game for the team. But that time too, it was not the way I play and I got out. Really disappointed with that. In the third game too, there was a good opportunity today to hold one end and try and play till the end, but couldn't do it. That's two things I'm really keeping in mind, how do I build from here? But that's how you learn and move forward."

It's perhaps a sign of the new-found consistency that Yadav has found in his game. He's in a patch of form where he's not had a 'bad' season, but cutting down on failures has not come at the expense of any inventiveness. Yadav still executes the ramps, the paddle-scoops, the drives, the flicks through the on-side while seemingly off balance.

"I've been a Mumbai boy," he said. "Growing up in Mumbai, the types of pitches you get in club games and in domestic cricket are very challenging. So there you automatically think what strokes you have to play on those kinds of wickets, and the same thing I've been carrying to the international stage. I'll be doing the same thing. Just trying to keep things simple, following my routines.

"The game remains the same. There's no change in the game, you play against any team, any level, you just have to go out and do the same things. What I do in domestic cricket, what I do in the nets, I try and do the same thing be it IPL, be it an international game. I just like to be myself. I like to go out there and enjoy. You must have seen, I just like to run when I get an opportunity to bat. I really enjoy that moment."

For now, Yadav is doing the running, and ensuring that even when India field a full-strength team, he's in serious contention to be part of it, whether in ODIs or T20Is. Like he said, how he builds his career is in his hands. So far, those hands have done a pretty good job.
