Keaton Jennings became the 19th Englishman to score a hundred on Test debut in the fourth match of the five-Test series against India at Mumbai’s Wankhede Stadium today. (Live Scorecard)Jennings, the son of South African former wicketkeeper and coach Ray, arrived in India only on Monday after being called up from the England Lions squad in the United Arab Emirates.Ray was also coach of the Virat Kohli-led Royal Challengers Bangalore.After Cook won the toss and opted to bat, the 24-year-old Jennings survived some nervous moments at the start but grew in confidence as he spent time at the crease.He was dropped by Karun Nair at gully off paceman Umesh Yadav before he had opened his scoring while India also wasted a review after Jennings was given not out to an appeal for leg before off Bhuvneshwar Kumar, who came into the side for the injured Mohammed Shami.Before the match, Cook had promised a more positive approach from his batsmen and it reflected during England’s opening stand of 99.Jennings, 24, was Alastair Cook’s 11th opening partner since Andrew Strauss’ retirement. The tourists, irrespective of what happens in this Test, would be happy to have found two solid young batsmen for the future. Hameed had scored a gritty 82 on debut in Rajkot and a gutsy fifty in Mohali.The left-handed rookie had amassed 1548 runs in county cricket including seven hundreds, the most by any player this season. Jennings repaid the faith by becoming the first England Test debut centurion since Jonathan Trott in 2009. Incidentally, Jennings was dropped even before he had got off the mark this morning.advertisementTwo other players in recent memory, Michael Clarke and Alastair Cook had scored hundreds on Test debut and went on to have great careers. Who knows how far Jennings might go from here? He certainly has the makings of a superb player.
