Kolkata, July 24 -- Back at the Harare Sports Club where he had helped India win the U-19 World Cup in February, Vaibhav Sooryavanshi became the youngest player to score a T20I half-century and take India to a comfortable seven-wicket win over Zimbabwe. Thursday's victory snapped a six-match losing streak. Sooryavanshi's 18-ball fifty ensured India were never bothered but this win was also set up by their fast bowlers who restricted Zimbabwe to 125/7. Mayank Yadav marked a dream return to international cricket with figures of 2/18 while Prince Yadav impressed with 2/19. Debutant Ashok Sharma also caught the eye despite finishing wicketless (0/29). Mayank's return to international cricket after almost two years out with a stress fracture could hardly have begun more dramatically. His first delivery, clocked at 149 kph, was a reminder of everything India had missed. Landing on a hard length outside off, it straightened just enough to kiss Brian Bennett's outside edge. The umpire heard nothing, but Ishan Kishan was convinced. Shreyas Iyer asked for a review, and UltraEdge confirmed the faint nick to send Bennett back for a golden duck. It set the tone for a spell that combined intimidating pace with impressive control. Mayank consistently operated above 145 kph, extracting awkward bounce and denying Zimbabwe's batters any rhythm. Dion Myers became his second victim, hurried into an ill-timed pull that found a fielder. The pace at the other end was no less significant. Prince, carrying the confidence from an impressive IPL season, rarely allowed Zimbabwe a chance to rebuild. Zimbabwe limped to 26/3 in the Powerplay before Sikandar Raza's dismissal deepened the crisis to 32/4. Ryan Burl offered resistance with 26, Wessly Madhevere compiled a patient 39 and Tadiwanashe Marumani's unbeaten 27 ensured Zimbabwe at least crossed 120. If Zimbabwe harboured hopes of defending the total, Sooryavanshi extinguished them almost immediately. By the time he sliced Richard Ngarava to deep third immediately after reaching his fifty, India had raced to 68 and the result was a mere formality. This despite Abhishek Sharma never looking comfortable, scratching his way to one before slicing Blessing Muzarabani to Brad Evans at the deep. Sharma's early departure handed the centrestage to Sooryavanshi. Richard Ngarava bore the brunt first. A short ball disappeared over deep square-leg. A fuller delivery was driven sweetly through the covers. Then came the shot of the innings: Sooryavanshi rocking back to a ball outside off and launching it over long-off. The left-hander's bat swing combined remarkable power with the fearlessness of youth. Sooryavanshi was on 48 from only 17 deliveries before another towering six off Muzarabani and a sliced boundary took him to the brink of history. His fifty arrived with an ungainly but effective loft over the bowler that fetched two runs, prompting applause from teammates and spectators alike. The celebration was brief. Ngarava tempted him with width next ball and Sooryavanshi, unwilling to retreat into caution, threw his hands at it and found deep third. But Ishan Kishan (35 off 24 balls) and Iyer (28* off 24) ensured India won with 40 balls to spare. Brief scores: Zimbabwe 125/7 in 20 overs (W Madhevere 39; M Yadav 2/18) lost to India 126/3 in 13.2 overs (V Sooryavanshi 50; B Muzarabani 2/26) by 7 wickets....
