Sri Lanka suffered an early collapse on day one of their second Test against Australia but steadied the ship late as Kusal Mendis kept the hosts on track.

Australia are not yet a great team but completing a series sweep in Sri Lanka would push them closer, according to spin bowler Nathan Lyon. Australia won the first test by an innings and 242 runs in Galle and will look to wrap up the series 2-0 with another win at the same venue when the second test starts on Thursday.
