• Moeen, Bairstow hit fifties to rescue England
• Off-spinner Mehedi claims 5-64 on debut

Only Root looked comfortable against the spinners, hitting five crisp boundaries in his fluent knock before Mehedi dismissed him to end his 62-run stand with Moeen.

Shakib dismissed Ben Stokes for 18 with a dipping delivery that turned sharply to breach the batsman's defence and hit the top of the off-stump.

Mehedi finally ended Moeen's vigil when he induced an edge which Mushfiqur collected behind the stumps.

Moeen's battling 68 included eight boundaries and a six and he raised 88 runs with Bairstow who became Mehedi's fifth victim.
