I am more happy as long as Mathews doesn't bowl longer spells. He is not a leading bowler al all.But he can play the holding role when his main bowlers get tired. If he gets a wicket, that is a bonus for the team. Prior to this series, Lakmal had been under a severe criticism as he hasn't delivered as expected. But if you closely look at his recent bowling efforts especially in Zimbabwe, he seemed to be gaining some kind of a rhythm (One would say that you can't count Zimbabwe tour but he bowled well in relative less seaming friendly flat hard decks) and it is important for him to keep that rhythm continue longer.
Pradeep has been bit disappointing so far during this tour as he didn't look threatening. In Prasad's case......actually,I don't write off him. He is no doubt a fine bowler who bowled with a lot of heart but, with his age and continuous injury issues, I think we should look for new options beyond him. Lahiru Kumara seems to have taken his chances with both hands. Look, he is still very young and generates decent pace with swing. So why wouldn't we try him as a new ball partner. I think he will be a fast learner and can be useful in challenging conditions.
I don't hesitate to bring Chameera back if he is fully fit. The reason is, we need to have a much more of a settled line up at least by now.I feel we have a settled spin attack and now we need look at our bowling and batting.If Chameera gets fully fit and bowls quickly,I think Lakmal,Kumara and Chameera can be our long term pace bowling options while we have options like Pradeep,Rajitha,Asitha,Vikum Sanjaya etc. Batting would have been settled if the batters didn't play carelessly in first two matches.
