R Ashvin, the tall 24 year old spinner from Chennai and one of the vital cogs of CSK's twin IPL titles. He has been hailed as country's second best spinner after Harbhajan in ODIs at least. He has just played 9 ODIs, 2 in World cup, 5 in NZ series and 2 in that ill fated Zimbabwe tour. But he has earned a place amongst fans to be brave hearted and a constant trier. He doesnt held himself back from tossing the ball up in the powerplays in ODIs and T20s, he gets thrashed but more often than not he picks up wickets.
He proved that in the IPL and CLT20 that he can be a very good new ball bowler and he often started the attack in the world cup (against West Indies and Australia - 2 games he played). Got Watson in the Quarters in the first 10 overs. And then he was dropped for the next 2 games. He again proved his mettle in the IPL when he constantly grabbed Chris Gayle in the final and a game before when later was rampaging.
MSD has handled this man very well and its fortunate for Ashvin that MSD is also India captain. When he returns for the England ODIs, Ashvin would be keen to perform well in the West Indies ODIs and sneak a place in the starting XI ahead of Harbhajan Singh. Its most likely that Harbhajan would always play ahead of him in conditions favoring just one spinner, but if Ashvin could keep Bhajji on toes, only the Indian bowling attack would be benefitted.
After Kumble's shoulder surgery of 2001, India hasnt had an attacking spinner in the ODIs. Harbhajan fitted that role very well in early 2000s but in last few years he has become more of containing bowler than an attacking bowler. He cannot be always relied to grab wickets in pressure situation, something which Kumble always did for Azharuddin and Tendulkar in 90s.
India has tried a lot of spinners in supporting role to Harbhajan after Kumble bowed out of ODIs -- Pragyan Ojha, Amit Mishra (very few ODIs), Yusuf Pathan, Piyush Chawala, Ravinder Jadeja etc. But none of them have been able to cement their places in the starting XI. Also Sehwag's dodgy shoulder in last 2 years havent helped India's cause, he has proved many times he is better off spinner than Harbhajan Singh.
If Ashvin is able to replicate his IPL success in ODIs and T20Is for India then not only he would be a serious contender for Tests but also India would have much better bowling attack as compared to now. He is in the team in West Indies only for the ODIs, but if he puts up a strong performance, say 2 wickets on average per game and giving away 4.5 - 5.5 runs an over, he would be very tough to ignore for the tougher tours coming up later this year.
And thats when Ashvin would be just Ashvin and not IPL Ashvin.
