Big picture - The ODI learning curve

And they said the middle overs in an ODI are dull. India and Sri Lanka are playing a series where all of the action is contained in the exact period where the 50-over format tends to be dull. And that's largely because they have been playing these games - the first of which ended in a tie - on pitches that challenge a batter, in ways that extend far beyond technique.

The Khettarama is asking people to play cricket thinking two overs ahead; to avoid the expansive drive just even if the ball seems to be tossed up, because that juicy half-volley is actually going to dip and turn to go past the middle of the bat and take the edge through to slip.

Restraint is the very thing that India have spent the better part of two years beating out of themselves, but now it is the very thing that stands between them and a bit of a black mark on a very proud record. They have lost only five out of 22 bilateral ODI series. They have won the last 10 rubbers against Sri Lanka - a streak that will come to an end regardless of the result on Wednesday - and that is tribute to the way this Sri Lanka side has performed even though it is missing several first-teamers. They are certainly shading the middle-overs battle, averaging 24.7 and losing only 10 wickets to India's 17.8 and 14 wickets.

Throughout the series, the aggression of Rohit Sharma at the top of the order has made Sri Lankan fans wax nostalgic about the days when their line-up was littered with all-time greats too. In the same way perhaps, India fans might be looking at Dunith Wellalage, all of 21 years old, shepherding Sri Lanka through back-to-back collapses like someone who used to do it for them. He is one of two men in this series to strike at better than run a ball and the other one has been playing this format for almost as long as he has been alive.

Whether India win and level the series or Sri Lanka win and claim it 2-0, these three games are likely to be an important learning curve for both teams and that is a check in the box next to why bilateral ODI cricket is still worth it (just, does it have to be eight hours long?).

In the spotlight - Virat Kohli and Avishka Fernando

Virat Kohli has only one fifty in his last 15 innings for India across formats. But here's the thing. He doesn't look out of form. And this is ODI cricket as well. He could probably write five different books about it - and star in their movie adaptations - and still not be done explaining how well he knows it. So a big score is probably on the horizon, and even if it isn't, he isn't the sort to be fussed about his numbers, not as long as he feels good in training and doesn't have to force himself to be involved. That's when there will be cause for worry.

Avishka Fernando is the best of both worlds. He can finesse the ball to the boundary, or if the mood strikes him, inflict that same ball to a whole lot worse. He puts attacking shots together like the rest of us put two and two together. It's just that natural to him. Except sometimes he might get carried away, which is why 26 of his 40 innings have ended at or before the 30-run mark and 17 of those innings have been single-digits. He'll be pushing himself to justify the talent he has and take his place as one of Sri Lanka's mainstays.

Team news - Does Parag have a chance?

Sri Lanka hit a sweet combination packing their side with spinners for the last game, which helped them drag India down from 97 for 0 to 147 for 6.

Sri Lanka (probable): 1 Pathum Nissanka, 2 Avishka Fernando, 3 Kusal Mendis (wk), 4 Sadeera Samarawickrama, 5 Charith Asalanka (capt), 6 Janith Liyanage, 7 Dunith Wellalage, 8 Kamindu Mendis, 9 Jeffrey Vandersay, 10 Akila Dananjaya, 11 Asitha Fernando

India might weigh up the pros and cons of Shivam Dube and Riyan Parag. Dube is a proven spin-hitter, which is sure to come in handy, but Parag offers them a bowling option that is better suited to the conditions. Or if they're feeling really funky, they might drop a quick bowler to bring in Parag and hand Dube the new ball.

India (probable): 1 Rohit Sharma (capt), 2 Shubman Gill, 3 Virat Kohli, 4 Shreyas Iyer, 5 KL Rahul (wk), 6 Shivam Dube/Riyan Parag, 7 Axar Patel, 8 Washington Sundar, 9 Kuldeep Yadav, 10 Mohammed Siraj, 11 Arshdeep Singh

Pitch and conditions: Bit of rain around

There are chances of showers in Colombo both leading up to and during the game, but it is unlikely that the whole thing will be washed off. Spinners have bowled twice as many balls (812 vs 351) as the quicks and picked up almost four times as many wickets (29 vs 8). Consider yourself warned.

Quotes

"We have very good batters. When it comes to their attack they've got great variety in legspin, offspin and left-arm spin. We need to find a way to put them under pressure. That's why a left-hander is in the middle in the middle overs."
