Young India A side had a day to forget as Australia A dominated Day 1 of the 1st unofficial Test. Sam Konstas bludgeoned an aggressive century to take them to 337/5 at Stumps in Lucknow. For India, Harsh Dubey made his point with 3 wickets. Here are all the India A vs Australia A match highlights: Australia have found it difficult to fill David Warner's boots at the top of the order. To compound their miseries, Khawaja at 38 is not young anymore. Konstas started his career during the Border Gavaskar Trophy, famously battling Jasprit Bumrah. He was however not preferred over with Marnus Labuschagne being one of the many options experimented with. Konstas hammered a century in a mere 120 deliveries on Tuesday, against some of the IPL veterans. A call to the side ahead of the Ashes would be no shock.

The left-arm spinner returned 3/88 from his 21 overs, providing guile and wicket-taking potential that was sorely lacking in the attack. Dubey topped the Ranji Trophy last season as the top wicket taker, even shattering records for most scalps in a single season. He takes the further steps with a brief stint at Sunrisers Hyderabad. India have a deep bowling lineup in Test matches, including Ravindra Jadeja, Kuldeep Yadav, Washinton Sundar and Axar Patel in the running. It may be sometime before Dubey gets into the queue but he is sending all the right signals to do just that.
