(ESPNCRICINFO) – THE first hour or so of play on the opening day of the Galle Test belonged to Sri Lanka. But after that, it was all Bangladesh, as Najmul Hossain Shanto and Mushfiqur Rahim struck centuries during an unbroken stand of 247, to seize control of day one.

By stumps, Shanto was unbeaten on 136 and had Mushfiqur right behind him on 105 not out. Seamer Milan Rathnayake was the most economical of the Sri Lanka bowlers, his 12 overs going for just 19 runs, but the bulk of the overs were bowled by the spin pair of Prabath Jayasuriya and debutant Tharindu Rathnayake. The wickets were split between Asitha Fernando and debutant Tharindu, but once Shanto and Mushfiqur were set, Sri Lanka rarely caused them trouble.

Winning the toss and opting to bat is usually the obvious call in Galle, but this time in particular, with conditions more favourable than usual for batters, Shanto was rightfully chuffed when the toss fell his way. That smile though, had become closer to a grimace when he stood at the non-striker’s end watching a third Bangladeshi batter fall with not even 50 on the board.
When Mushfiqur walked out to join him, Shanto himself had faced just three deliveries; it took him only until his sixth though to show that he would not be cowed by the situation, skipping down the track and smoking one back over Tharindu’s head. That set the tone, if not outright aggression and displayed resolute confidence.

Tharindu had at that point been building up a head of steam. Mominul Haque had gone after him, but the ambidextrous spinner had the last laugh. And prior to that, he had removed opener Shadman Islam. Shanto though, made it a mission to put Tharindu off his rhythm; he would end the morning session having struck at better than run-a-ball against the spinner, and would continue to target him as a release valve of sorts throughout the day. Of Shanto’s 15 boundaries (14 fours and a six), ten came off Tharindu.

Tharindu eventually settled in and brought down his economy rate, but Shanto and Mushfiqur continued steadily on, the run rate always hovering around 3-3.5 an over. The session counters reflected as much – 90, 92 and 110. The last session might have been less, after Sri Lanka began utilising defensive lines for the first hour, but they got tired in the final hour and it allowed Bangladesh to tick along at nearly four an over during that period.

Considering the batter-friendly nature of the pitch, an argument could be made for Bangladesh perhaps having been able to go harder at the Sri Lankan bowlers, but even with the pitch taking less turn on day one than what it has in the past, the conventional wisdom in Galle has been to bat first and long, and Bangladesh are set up to do just that.
