Australia overcame Steve Smith’s absence and survived another venomous spell from Jofra Archer to draw the second Test with England and retain their slim advantage in the Ashes.An intriguing, rain-affected encounter at Lord’s concluded with neither side able to forge a positive result, despite England bidding to force the issue when declaring on 258-5 in the second session after Ben Stokes (115 not out) had posted a century. Joe Root’s attack had enough incentive with 48 overs remaining, while a target of 267 was also encouraging for the tourists, even if Smith was unavailable having displayed concussion symptoms on Sunday after copping an Archer bouncer on the third day.Archer (3-32) dismissed David Warner and Usman Khawaja inside the opening six overs, but Smith’s concussion replacement Marnus Labuschagne’s gritty half-century effectively ended England’s hopes, despite Jack Leach (3-37) striking with back-to-back deliveries and Joe Denly’s brilliant catch, as Australia ended on 154-6.20 – This is the first drawn Test in England since June 2016 (Eng v SL); ending a run of 20 matches without one.

Labuschagne may be needed at Headingley if Smith cannot return, and here he showed he is up for the fightMOMENT OF THE DAY A diving Denly plucking the ball out of the sky with his left hand after Paine had pulled Archer to the midwicket region. It deserved to be more than just a mere footnote in the contest.KEY OPTA FACTS:— No bowler has taken more Test wickets since the start of 2018 than Pat Cummins (71 — same as Kagiso Rabada).— None of England’s previous 20 Tests on home soil had ended in a draw — the last was against Sri Lanka in 2016.— Warner has been dismissed for single figures in all four innings so far in this Ashes series.— Australia opener Bancroft was dismissed lbw twice in a Test for the first time in his international career.— Stokes recorded his second century at Lord’s — he made 101 against New Zealand back in May 2015.
