Teenage sensation Sam Konstas announced his arrival on the international stage with a stunning half-century on debut as Australia raced to 112 for 1 at lunch on the opening day of the fourth Test against India at the Melbourne Cricket Ground (MCG) on Thursday.

The 19-year-old Konstas dazzled with a quick-fire 60 off just 65 deliveries, showcasing the fearless stroke play that has earned him much acclaim. Australia, opting to bat on a pitch that promised runs, saw Konstas form an 89-run stand with veteran Usman Khawaja, who remained unbeaten on 38 at the break. Khawaja was joined by Marnus Labuschagne (12 not out) as the hosts looked to consolidate their strong start.
