Who will open the batting for England in The Ashes?
England look to have one of the strongest opening pairs they have had for some time and they will be hoping that Ben Duckett and Zak Crawley will continue their strong form in the Ashes.
England go into an eagerly anticipated summer of Test cricket hoping Ben Duckett and Zak Crawley have finally solved their long-standing problems at the top of the order.
Duckett's average of 56.44 is by far the highest of any England opener since Sir Alastair Cook's retirement nearly five years ago, while his strike rate of 95.49 is arguably of even greater importance in the Brendon McCullum/Ben Stokes era.
He and Crawley average over 48 as a partnership, albeit in just five matches to date, and here the PA news agency looks at their record in contrast to what has gone before.
Immediate impact
Crawley and Duckett's first innings together set the bar high as they put on 233 against Pakistan in Rawalpindi in December.
Those runs came in just 35.4 overs at a rate of 6.7 per over as both men scored centuries - as did Ollie Pope and Harry Brook, all at over a run a ball apart from Duckett's 107 from 110 balls.
It would be asking a lot for their partnership to live up to those heights since, and Duckett was dismissed first ball in the second innings, but in two of the four Tests since they have a fifty partnership to their name - 87 in Karachi and 52 against New Zealand at Mount Maunganui.
Even their 38 in Multan and 39 in Wellington would be an improvement on England's average opening partnership of 28.40 since Cook retired, while their strike rate has settled at a still-impressive 5.70 per over.
The last five years
Duckett is the 12th opener used by England in 56 Tests since Cook's departure, with only five of those even averaging over 30.
His average is almost 10 runs clear of the field, though second is regular tail-ender Jack Leach whose 46.50 comes from scores of 92 and one in two innings as a nightwatchman. Captain Ben Stokes has no average as an opener, having scored 78 not out from 57 balls in his only innings.
Keaton Jennings, Joe Denly and Rory Burns average narrowly over 30 while Crawley is at 25.19, which also ranks him behind Dom Sibley. His strike rate of 57.90, while pedestrian by England's new standard, ranks third in that time and rises to 83.47 in innings partnering Duckett.
Haseeb Hameed limped to an average of 19.18 and a strike rate of 30.80, Alex Lees was not much better at 23.84 and 43.06, Jason Roy made only 62 runs in seven innings and Jos Buttler was promoted once as a pinch-hitter but failed to score.
The only other post-Cook pairings to average even 30 are Burns' partnerships with Hameed (39.14) and Crawley (35.00).
Long-term trend
The issue has existed ever since the departure of Cook's predecessor as captain, Sir Andrew Strauss, back in August 2012.
Cook averaged 42.52 from 144 innings in that time but only three other openers hit the 40 mark.
Encouragingly, one of those is Duckett with 46.15 for his full 14 innings as an international opener. His strike rate across that whole period sits at 89.55.
Joe Root spent 11 innings at the top of the order and while his average of 41.70 was more than creditable, it was well down on his overall Test average of 50.22. Leach is the third name on the list, in the two aforementioned innings.
