Despite Pakistan losing three early wickets, the target was never out of reach as Babar and Malik shared an unbroken 119-run fourth-wicket stand. Malik smashed Milinda Siriwardana for a boundary and a six to seal the victory. He hit three sixes in all and two boundaries in his 81-ball knock while Babar, who had scored successive hundreds in the first two matches, had five boundaries off 101 balls.He's the top ODI wicket-taker of 2017 - @RealHa55an has risen 6 places to go top of the @MRFWorldwide ODI bowling rankings for the 1st time! pic.twitter.com/qfREnYLx7P

Pakistan lost Imam-ul-Haq for two after his debut hundred in the last match while Fakhar Zaman fell for 17 and Mohammad Hafeez made nine. This was Pakistan's eighth consecutive win which also included their 2017 Champions Trophy triumph in England and Wales in June while Sri Lanka succumbed to their 11th consecutive ODI defeat. The fifth and final match is also in Sharjah on Monday.Breaking news: Hasan Ali becomes number one bowler in the ICC ODI Rankings. #PakvSL

Earlier, Sri Lanka got off to a disastrous start when their in-form skipper Upul Tharanga was bowled by debutant left-arm pacer Usman Shinwari for nought off his second delivery. Shinwari was one of two changes Pakistan made from the third one-dayer which they won by seven wickets in Abu Dhabi. Also brought back was Wasim. They replaced Fahim Ashraf and Rumman Raees. Sri Lanka had made three changes, with Sadeera Samarawickrama making his debut.I love you Pakistan! Onwards upwards loads more records to achieve loads more records to break loads more records to set!! #NO1 #ICC #2017?? pic.twitter.com/yfUO0eIkDc

Another left-armer Junaid Khan ended Niroshan Dickwella's enterprising 16-ball 22, studded with three boundaries and a six, while Dinesh Chandimal was run out for 16. Samarawickrama lasted just two balls without scoring before Thirimanne and Siriwardana (13) added 32 for the sixth wicket. Shadab then removed Seekuge Prasanna (five) and Thisara Perera off successive deliveries before Hasan came into his wicket-taking acts.Congrats @RealHa55an to become no1 Bowler in Odi rankings, proud of you my boy. we need to even work harder to mentain no1 ranking iA.
