The 2019 World Cup hosts have just a few days to recover from a stunning one-day global defeat before they face title-holders Australia in the first of a five-match series at The Oval on Wednesday.
'We're delighted to be working with Cricket Scotland and to have Calum, Safyaan and Grant on board for our Vitality Blast campaign, ' said Derbyshire cricket advisor Kim Barnett.
"To be captain of the team is a huge honour and massive privilege, so I am just looking forward to getting into it on Wednesday", he said.
But Derbyshire have moved quickly to secure the 85-cap global batsman on the back of his seventh ODI hundred as part of a new relationship between the midlands county and Cricket Scotland.
He will be up against Jonny Bairstow who is enjoying a rich vein of form and will be taking guard in the match after scoring three successive hundreds in this format.
Touring captain Tim Paine has asked England counterpart Eoin Morgan if both sets of players can indulge in the football-style ritual, as part of the visitors' charm offensive. First of all, it's great for Scotland.
"Our bowlers missed their lengths and lines a little bit and with the bat we didn't play as good cricket as we would have liked. I think it's going to be a good series".
The International Cricket Council's decision to shrink the World Cup from 14 teams to 10 had already been heavily criticised long before Scotland and their fellow associate or non-Test nations impressed with the quality of their play in Zimbabwe. "It is up to us now to build on it", he said.
"We were miles off where we expect to be and didn't do enough to win".
Scotland's shock one-day global win over England has boosted their chances of securing test-playing status, the country's cricket board has said.
