Riding on Ajinkya Rahane's fifty Rajasthan Royals beat SunRisers Hyderabad by six wickets to notch up their fourth consecutive win in this edition of the IPL cricket tournament here on Thursday. Chasing a modest 128 for a win, the table-toppers made heavy weather of the run chase, achieving the target on the last delivery of the match. The SRH bowlers did well to take the match thus far but Rahane's 56-ball 62 proved to be the difference between the two sides. Man-of-the-match Rahane, who registered his first half-century of the this season, and Sanju Samson (26) worked well for their 64-run opening stand before a few wickets made the match exciting in the end. A chance for SRH came in the seventh over when Samson clubbed the ball in the mid-off region but the skier was floored by Ashish Reddy after the fielder got to the ball by making good ground but failed to pouch it. The unlucky bowler was Praveen Kumar. But come the 11th over and Ravi Bopara was more than lucky as wicketkeeper Naman Ojha came up with a brilliant diving catch to send back Samson back in the dug out to give SRH some hope. The wicket did dry up the flow of runs for the visitors, but the lack of runs on the board helped their cause as Rahane stayed on with skipper Steven Smith (13) to bring them closer to a win. Smith (135 in 4 matches), who was overtaken by opposition captain David Warner (131 in 3 matches) in the first innings, edged out the Australian in the run-scorers list but Rahane (155) it was who surpassed the two to wear the Orange Cap.
