Sri Lanka suffer 12th straight defeat

Playing just his second ODI, Usman Khan destroyed Sri Lanka's top-order, striking four times in 11 balls and then completing a five-for off his 21st delivery. Since 2001, only two bowlers have completed a five-wicket haul in fewer balls. Chaminda Vaas did it in 16 balls against Bangladesh in Pietermeritzburg in the 2003 World Cup, which included a hat-trick from the first three balls of the innings, and Netherlands' Timm van der Gugten completed a five-for in 20 balls against Canada in 2013. Usman is only the second Pakistan bowler after Bilal Asif to take a five-wicket haul in his first two ODIs. Bilal also did it in his second match, in 2015.

All downhill after winning the toss

Sri Lanka, trailing 4-0, chose to bat first after they called right at the toss. That turned out to be the only good thing to happen to them all day. They lost two wickets in their first over, two in their third and were four down with only eight runs on the board. Only once have they lost their fourth wicket at a lower score. Three of their top five batsmen were out for ducks - Sadeera Samarawickrama, Dinesh Chandimal and Niroshan Dickwella, and this was only their third such instance in ODIs.

The visitors couldn't really recover from that nightmarish start and were eventually all out for 103, in 26.2 overs. It was their shortest innings, and second-lowest score, after choosing to bat first. It was also the fewest overs Pakistan have taken to dismiss their opposition after losing the toss and having to bowl first.

Sri Lanka's innings was the ninth-shortest for any team after electing to bat first.

Five consecutive tons in the UAE for Babar Azam

Pakistan's young sensation Babar Azam raced to his seventh ODI century in just his 33rd innings, making him the quickest to the mark. He got there eight innings quicker than, who scored it in his 41st innings. Among Pakistan batsmen, the quickest was Zaheer Abbas in 42 innings.

The century in the second ODI was Azam's fifth successive one in the UAE. He's the first ever player to score five consecutive centuries in a country. He had hit three in three games against West Indies last year before this series. The previous record holder in this case was AB de Villiers with four tons in a row in India. Among Pakistan players, Zaheer Abbas and Saeed Anwar had scored three successive tons in the UAE. Azam's five tons are now the second-most by any player in the UAE, trailing the seven scored by Anwar and Sachin Tendulkar.

Azam scored his first century on September 30, 2016 and has made seven since. All other Pakistan batsmen have a combined three hundreds in this period: one each for Azhar Ali, Shoaib Malik and Fakhar Zaman. David Warner is the only other player to score seven centuries in this period.

One thing that has stood out in the last 13 months is his Azam's conversion rate of fifties into hundreds. In the 18 innings since the start of series against West Indies last year, Azam has failed to make a century only once after going past 50. That was against Australia at the WACA, when he was dismissed for 84. In 15 innings prior to this period, he had scored five fifties but couldn't convert any of those into hundreds. Out of 11 players who have scored three or more centuries in this period, no other player matches the fifties to hundreds conversion rate of Babar's 87.50%. Warner is next on the list with 77.78% - with seven hundreds from nine 50-plus scores.

Sri Lanka's first-innings feast, second-innings famine

The Sri Lanka batsmen put in contrasting performances in both innings in their first ever day-night Test in Dubai. After putting up 482 runs in 159.2 overs in the first innings, they were bundled for just 96 in 26 overs in the second innings. This was only the sixth instance in Tests when a team was bowled out for under 100 after posting a 400-plus total in their first innings. Sri Lanka were involved in the previous instance as well, with scores of 400 and 82 against England in Cardiff in 2011. No other team has done this after 2000.

The difference in Sri Lanka's totals was 386 runs, which is their highest ever difference in totals of two innings in a Test. Their previous highest was 383 against Australia in Colombo (SSC) in 1992. It was also the first instance of any team having a difference of over 350 runs in their totals in a Test against Pakistan. Sri Lanka had a lead of 220 in the first innings. Their second-innings total of 96 is the lowest for any team after gaining a first-innings lead of over 100 runs. The previous lowest was South Africa's 99 against Australia in Durban in 1950 after having a lead of 236.
