Rahim's blinder helped Bangladesh chase down a mammoth target of 215 with two balls to spare. Gunathilaka scored 26 runs while Kusal Mendis and Kusal Perera recorded impressive half-centuries to bring up the Sri Lankan total to 214 in their 20 overs.
The wicket-keeper batsman has shown the way to utilise footwork to the Bangladesh top order and, as Bangladesh skipper Mahmudullah Riyad described during the post-match presentations, the Tigers think tank knew that the Sri Lankans would open with an off-spinner in the form of Akila Dhananjaya. They lost their opening match against Sri Lanka but bounced back to win their second match of the series against Bangladesh.
In reply Bangladesh started well with Tamim Iqbal (47) and Liton Das (43) getting them off to a flawless start.
In what came as only the fourth highest successful chase in T20 internationals, Bangladesh stunned Sri Lanka by chasing down 215. It is also a must-win game for Bangladesh as another loss will make it very hard for them to make the final on March 18.
A single win would quell worries, Tamim had said after the first practice session in Sri Lanka. Did not bat: Perera, Chameera, Fernando Bowling: Taskin Ahmed 3-0-40-1; Mustafizur Rahman 4-0-48-3; Rubel Hossain 4-0-45-0; Mehedi Hasan 4-0-31-0; Nazmul Islam 2-0-20-0; Soumya Sarkar 1-0-11-0; Mahmudullah 2-0-15-2.
Tamim went on to score 47 off 29 deliveries, which included six boundaries and a six, before he was caught and bowled by Thisara Perera. The left-arm pacer has picked up four wickets in two matches so far but leaked runs which is not expected while spearheading the attack.
On the bowling front, Jaydev Unadkat needs to be more consistent.
