Just a day after admitting the need to show more responsibility in converting starts into bigger scores, Bangladesh opener Tanzid Hasan Tamim lived up to his words.

The left-hander smashed a blistering 59-ball 103 -- his first List A century in two years -- to power Legends of Rupganj to a thumping ten-wicket victory over Partex Sporting at BKSP Ground 3 in Savar today.

Tanzid's exploits helped his side chase down Partex's 129 all out in just 18.3 overs in the 50-over fixture.

The 24-year-old -- who had not found that elusive three-figure mark in List A in 46 innings, but found starts in international cricket, most recently in the Champions Trophy -- struck a boundary off Md Rakib to bring up his ton and the winning runs.

Rupganj bowlers had set the game up for Tanzid's carnage. Pacers Shoriful Islam and Rejaur Rahman bagged two each, while Mahedi Hasan picked four for 34. The outcome meant they are fifth in the standings, still in line for qualifying for the Super Six with five wins.

Meanwhile, at BKSP Ground 4, Agrani Bank stunned Brothers Union with a four-wicket win, courtesy of Taibur Rahman's four-fer and 35 with the bat.

Asked to bat, Brothers batters managed starts. Mizanur Rahman managed 44, while Aich Mollah notched 33 before veteran Alok Kapali's 57-ball 58 helped them to 238 for nine.

Agrani's chase had a similar look to Brothers' innings, but Taibur and Shuvagata Hom (45 not out off 35) helped avert a collapse after three quick wickets, ensuring they remain fourth in the standings.

Elsewhere, in Mirpur, the focus was very much on Nasir Hossain, who returned to domestic action a day after his two-year ban for breaching ICC's Anti-Corruption Code was lifted.

Nasir appeared for Rupganj Tigers in their fixture against Gazi Group and helped his side upset the third-placed team with an eight-wicket victory, with 16.3 overs to spare.

Electing to bowl, Rupganj operated with Nasir from the start, and the 33-year-old off-spinner conceded 31 runs in the 10-over spell, returning with a wicket, while five others chipped in with wickets to bundle Gazi out for 159 in 42.1 overs.

In reply, Rupganj openers Abdul Majid and Amit Majumder both struck fifties to lay the platform for a smooth chase, before Nasir fell for nine after coming to the middle in the 30th over.
