Mosaddek Hossain Saikat is a cricketer who has played first-class and List A cricket in Bangladesh since 2013. In 2014-15 he made 250 and 282 in consecutive first-class innings and passed 1000 first-class runs in his 10th match. In October 2015, in his 12th first-class match, he became the first Bangladeshi player to score three double-centuries. He made his Test debut in March 2017.
Under-19 career
Hossain is a right-handed batsman and off-spin bowler. He played for Bangladesh in two ICC Under-19 World Cups: in Australia in 2012 and in Abu Dhabi in 2013-14. He captained Bangladesh Under-19 in a two-match series of four-day matches against Sri Lanka Under-19 in April 2013, scoring 107 in the first match and 74 in the second. He then captained the team again in a five-match series of limited-overs matches immediately afterwards, scoring more than 200 runs, including 98 in the third match which Bangladesh win by one wicket. In England later that year, in a "superb all-round performance", he scored 110 not out off 113 balls then took 3 for 38 off 10 overs in a 38-run victory over England Under-19.
Senior career
At the age of 17 he made a century in his second List A match when he scored 100 for Abahani Limited against Prime Doleshwar Sporting Club in 2013-14. He played one first-class match for Dhaka Division in 2013-14 and was selected to play for East Zone at the end of the season, when he took 3 for 65 and 4 for 33 against South Zone. After the 2013-14 season Cricinfo named him as one of Bangladesh's most promising young players, noting that as a batsman he impressed "with his footwork against spin and ease against pace". He played for Barisal Division in the 2014-15 National Cricket League. Against Rangpur Division at Savar he scored 250 off 448 balls, adding 423 for the fifth wicket with Al-Amin. His previous highest first-class score had been 13, and Al-Amin's was 64. In his next innings a few days later on the neighbouring cricket ground, Hossain scored 282 off 309 balls. Both matches were drawn. In the second innings of the last match of the season he scored 119 for South Zone in the Bangladesh Cricket League, taking him past 1000 for the season and his career. He began 2015-16 with 122 and 40 for Barisal Division, top-scoring in each innings, and scoring the first century of the worldwide 2015-16 season. In the next match he scored 200 not out and 61, again top-scoring in each innings. Both matches were drawn. His 200 not out made him the first Bangladesh batsman to score three first-class double-centuries. He toured South Africa and Zimbabwe with Bangladesh A in October–November 2015. He was Bangladesh A's top-scorer in the two first-class matches, against Zimbabwe A, with 194 runs at 64.66. In October 2018, he was named in the squad for the Chittagong Vikings team, following the draft for the 2018–19 Bangladesh Premier League. He captained Abahani Limited to victory in the 2018–19 Dhaka Premier Division Cricket League. In November 2019, he was selected to play for the Sylhet Thunder in the 2019–20 Bangladesh Premier League.
