We would all love for Lyon to be taking 5 wicket hauls and winners us games but ts rare that any spinner does so early in there test career. I think lyon looks a good bowler considering his only 25 and has a lot of improvement left in him. The best three spinners in the world Swann(33),Herath(34) and Ajmal(35) have not really been match winners till there 30s so to have Lyon already performing an important role in the team can only be positive. Yesterday he played better then he is getting credit for thou by shutting down one end and allowing the quicks a chance at the another, a similar role to what Hilfy does when he bowls with Siddle and Starc.
