The secret to Marcus Trescothick's dramatic return to form, it turns out, is nothing to do with a tweak in technique, equipment or training method. It's all about sleeping as far away as possible from his new-born daughter.
The England opener put a poor start to the season behind him on Friday by scoring 194 out of England's 528 for three declared at Lord's against Bangladesh.
"I was batting the other week and yawned as the ball came down," he told a news conference.
"I told my wife I needed a little more sleep so I went up to the top of the house -- fortunately it has three storeys, so you can't hear anything -- a week before the Test.
"Having a daughter is fantastic but having disjointed nights at home has obviously not helped my cricket."
The 29-year-old left-hander, whose daughter was born last month, was on the brink of a second Test double-century when he snicked a catch behind off spinner Mohammad Rafique to end his six-hour, 259-ball marathon.
"I thought I played really well," he added. "It's nice to spend time in the middle. I wanted to make the most of it.
"It began clicking for me on Wednesday (on the eve of the Test match). I stayed back for an hour's batting and got a bit more into the groove. Throughout my innings here it was getting better and better."
Trescothick's hundred was his 11th in his 60th Test.
