This 'A Team' tour is a good opportunity for young cricketers to make an impact against some talented players. Unadkat's 13fer will surely catapult him into the selectors minds for the medium to long term. Of course, more performances are needed, but such an effort cannot go unnoticed. Dhawal was unsuccessful in this game but performed well in the first, showing that he can be taken seriously both inside and outside of India. A lot of the time, it has been suspected that domestic medium pacers succeed on slow, low tracks through attrition, but in very different English conditions, success can go a long way for him too.
Having seen both bowl, I think both bowlers could have India futures ahead of them. Dhawal has to work somewhat on his speed, but I recall reading that he has intention to do so. Bridging the gap from 125kph to 130-135kph is crucial and is the difference between a journeyman seamer and a genuine international medium pacer, imo. Strength training, numerous years getting truly used to the bowling action (something which, say, Saj Mahmood, still hasn't done) can all add the extra yard of pace. He has had good consistent success in the domestic circuit and if he keeps this up, he may be able to pry the second seamer's spot. Domestic performances are key even for Indian seamers, note how the out of favour Sreesanth never took wickets for Kerala and the formerly prolific RP Singh was poor for UP in FC cricket this year. Zaheer Khan, however, tends to go to domestic cricket and pick up wickets - he is sometimes expensive, but he knows to pitch it up, swing it and ends up with 3 or more. Ishant played a game or two for Delhi this year too, and didn't do too well either, cannot take too much from that, but if someone does not perform domestically, they won't internationally and the opposite is true, at least to some extent.
