Australia's veteran off-spinner Nathan Lyon was still in a state of disbelief after completing 500 Test wickets during their thumping 360-run victory over Pakistan on Sunday in the first Test of the three-match series. The 35-year-old walked into his first Test for Australia after picking up an injury during the Ashes earlier this year. He entered the Optus Stadium just four wickets shy of the 500-wicket landmark. In the first session, he scalped three, needing just one wicket in the second session to reach the remarkable feat. With Australia pacers removing Pakistan batters at a brisk pace, it seemed as if Lyon would have to wait for another Test to pick his 500th Test wicket.
