Meh, young fast bowlers are a rarity. Mithun is solid, but has played only one season. Lately, Unadkat has been hyped, but he hasn't played any Ranji cricket yet. From what I saw in the U-19 World Cup though, I can say that Unadkat has potential, but lacks control at this stage.
Watching today's match, Tyagi's lost pace, going down the traditional Indian bowler route, Rahane is in some awesome form, but got out to the short ball, Jadeja is awesome against domestic attacks, Saurabh Tiwary was looking good until he got run out and as long as Indian domestic teams consist of medium pacers and spinners, Yusuf Pathan will be dangerous.
Bit disappointed with Pandey and Kohli, hope they come good later in the tournament. Pandey needs to stop being so circumspect at the start of an innings, it's his main weakness imo(Dhawan took a brilliant reflex catch to dismiss him today though), and Kohli looked good today while he was out there.
India Red's fielding was highly impressive, except for Yusuf Pathan, and they have a lot of players from that U-19 Winning team - Pandey, Kohli, S Tiwary, Abdulla. Mukund was a part of India Red before his call-up to the national side as well. Goswami and Jadeja from that squad are a part of India Blue, and I believe Srivastava is a part of India Green. Sangwan's fall has been disappointing though, hope he gets his act together this season.
