Mumbai, April 22 : Jos Buttler’s third IPL 2022 century followed by Prasidh Krishna’s three-wicket haul guided Rajasthan Royals (RR) to a 15-run victory over Delhi Capitals (DC) here at the Wankhede Stadium on Friday. Buttler (116 off 65) powered Royals to 222/2, the season’s highest total. The Englishman now has four tons in 71 innings in his all-time IPL career, needing one to move past Virat Kohli (5 hundreds in 206 innings) and two more to displace Chris Gayle (6 centuries in 141 innings). At one point 223-run target looked imposing, but Rovman Powell brought it down to 36 off 6 balls. Royals skipper Sanju Samson handed the ball to Obed McCoy. Powell got entire stadium on its toes as he whacked three consecutive sixes. With three maximums needed, Capitals dugout lost its cool, demanding a check for a no-ball on height. However, the on-field umpire declared it a legal delivery. This made DC skipper Rishabh Pant angry and he signalled his batters to leave the field, before sending coaching staff member Praveen Amre in the middle to question the umpire. At last the match resumed and a dot ball by McCoy ruled out Capitals’ chance to win the match. Powell’s (36 off 15) heroics came to an end on the final ball as he was caught behind. Early wickets by Prasidh (3/22) and Ravichandran Ashwin (2/32) dented Capitals’ chase. In-form opener David Warner (28) was the first one to fall. The dismissal of Prithvi Shaw (37) and Pant (44) tilted the match in favour of Royals. With the run rate climbing up and lack of support at the other end, Capitals’ chase looked like a far fetched dream. Earlier in the day, Royals openers Buttler (116 off 65) and Devdutt Padikkal (54 off 35) took calculated risk after being put into bat, with Buttler playing second fiddle to Padikkal thanks to Shardul Thakur who conceded just six runs in his two overs in the powerplay. Buttler, who was relatively slow initially, caught up with Padikkal once the restrictions were lifted. Although Royals scored 87 runs in the first 10 overs, their batters were merciless in their approach against Capitals bowlers. Some poor fielding on Delhi Capitals’ part besides Khaleel Ahmed (4/47), Mustafizur Rahman (4/43), Lalit (4/41) and Kuldeep Yadav (3/40) leaking too many runs added to Royals’ advantage. Khaleel finally gave Capitals some relief as he ended the 155-run opening partnership. The left-arm pacer trapped Padikkal soon after his fifty on the first delivery of the 16th over. Skipper Samson joined Buttler for the final five overs, which saw Royals add 67 runs. The Englishman raced to his century off 57 balls. In the penultimate over, Mustafizur got rid of Buttler, whose 65-ball innings was decorated with nine sixes and nine boundaries. Shardul, who wasn’t handed the ball after the powerplay, returned for the final over, raising questions surrounding Pant’s captaincy plans. Samson smashed 18 runs, including two fours and one maximum, to finish on 46 not out off 19 balls.
