India came into the fourth Test match at the back of 137-run victory in the Boxing Day Test. India could not stick to the same XI due to the unavailability of two players. While Rohit Sharma flew back to India to see his new-born daughter, Ishant Sharma was dropped from the side as he got himself injured.To replace Rohit, India chose to bring back KL Rahul as the opener and that meant that Hanuma Vihari was back at No. 6. The other selection move was a bit of surprise as India opted for the second spinner in the form of Kuldeep Yadav.KL Rahul failed yet again as he got out for just 9 runs. The other Indian opener, Mayank Agarwal then stitched a crucial 116-run partnership with Cheteshwar Pujara.Mayank Agarwal played cautiously throughout the innings. He was tested by some serious Aussie short bowling but the young opener managed to score his second Test fifty. Agarwal tried to up the ante after the landmark but got trying to hit Nathan Lyon for a third six.Kohli and Pujara then steadied the innings by adding another 50 runs before the Tea break. Just after the tea break Kohli and Pujara were expected pile on a lot of runs together but Kohli's soft dismissal in the very first over after Tea ended the partnership worth 54 runs.The Indian vice-captain, Ajinkya Rahane then joined Pujara in the middle. Rahane tried his best to stay in the game but a sharp bouncer from Mitchell Starc shortened his stay in the middle. Even with wickets falling at the other end, Pujara did not lose his composure and notched up his third century of the series.After Rahane's dismissal, Pujara and Hanuma Vihari ensured that India did not lose another wicket before the end of the day. In less than 20 overs, they added 75 runs for the fourth wicket. With Vihari scoring some quick runs and Pujara batting solidly at the other end, India will look to go past the 450-mark on Day 2.Here's how Twitter reacted to Day 1 of the New Year's Test between India and Australia:Most batsmen shadow bat a forceful drive or two when they are walking out. Not Che Pujara. #AUSvIND pic.twitter.com/sFR88bwAkX— Adam Collins (@collinsadam) January 2, 2019You blink your eyes, KL Rahul gets out.You sleep 8 hours, Pujara still playing.#INDvAUS— Sunil- The cricketer (@1sInto2s) January 3, 2019Rahul played six balls:Outside edge, squared-up, inside edge, outside edge, defended off back foot, outside edge (gone).Pujara's first six balls:Tap to leg-side, left alone, defended, left alone, blocked, blocked.#AUSvIND— Suneer (@suneerchowdhary) January 2, 20193 hundreds in the series, more than 400 runs, most of these made in masterly fashion. @cheteshwar1 has not merely blunted the Aussie attack, he’s nade it wilt. In many ways, he’s been the difference between the two sides. Epic performance!👏👏👏— Cricketwallah (@cricketwallah) January 3, 2019Zindagi na milegi Pujara. Brilliant to watch the determination and the consistency has been amazing.Congratulations @cheteshwar1 on your third hundred of the series.— Virender Sehwag (@virendersehwag) January 3, 2019Pujara for endorsing Cement. You won’t find a better brand ambassador 😊🙌👍 #AusvInd #7Cricket @7Cricket @1116sen— Aakash Chopra (@cricketaakash) January 3, 2019#Pujara after he was dropped from the Edgbaston Test against England1, 17, 14, 72, 132*, 5, 37, 0, 86, 10, DNB, 123, 71, 24, 4, 106, 0, 107* (still on)809 runs at an average of 53.93 with FOUR tons. A better average than the skipper and more tons too. #AUSvIND #AUSvsIND— Rohit Sankar (@imRohit_SN) January 3, 2019You look at the tired Australian bowlers, it is a result of the last Test where India had them out for two days. Test cricket is tough on the body.— Nikhil 🏏 (@CricCrazyNIKS) January 3, 2019Delight to watch proper grinding Test Match batting. And we must remember, that while Australia’s batting is depleted, they are playing their full strength bowling attack. Top class from @cheteshwar1 Pujara !— Mohammad Kaif (@MohammadKaif) January 3, 2019Why isn't Pujara doing push ups?— Dennis Pinkjara (@DennisCricket_) January 3, 2019You know you are below average when Pujara is smacking you for three fours in an over in a Test.— Nikhil 🏏 (@CricCrazyNIKS) January 3, 2019Once Agarwal has 10 Tests under his belt and gets comfortable that he belongs, watch him revolutionise opening batting. Sehwag v2.0Will go big. Will go fast. #AudvInd— Dennis Pinkjara (@DennisCricket_) January 3, 2019Both Pant and Paine can go to Dhoni to babysit and learn about DRS?— Nikhil 🏏 (@CricCrazyNIKS) January 3, 2019You know Australian cricket is in a dark place when people are suggesting David Warner as the solution. #AUSvIND— Titus O'Reily (@TitusOReily) January 3, 2019KL Rahul knows something very bad about Kohli or Shastri.— Kuptaan 🇮🇳 (@Kuptaan) January 3, 2019Only year changed and KL Rahul remains the same...— Broken Cricket (@BrokenCricket) January 2, 2019Virat Kohli: What was the need to bat at a strike rate of 150 and lose your wicket?KL Rahul: pic.twitter.com/FDQmR9dScD— Sir Jadeja (@SirJadeja) January 3, 2019KL Rahul's instagram story lasts longer than his inning. #AUSvIND #INDvAUS— Sir Jadeja (@SirJadeja) January 3, 2019BREAKING: ICC accused Australians of fixing as they didn't manage to get KL Rahul out on 0.#AUSvIND pic.twitter.com/tsTyiW6ZoM— Breaking News (@tazaa_samachar) January 2, 201915 years after Steve Waugh played his last Test against India at the SCG, his son Austin is carrying the drinks & reserve fielder.
