England's victory margin was eventually a convincing one, but they made life hard for themselves before finally putting away a side 136 places below them in the world rankings.
It was no surprise that England's vast superiority and fitness finally proved all too much, despite the visitors' determined defence.
Once Kane doubled England's advantage midway through the second half, it became even more of a damage limitation exercise for Latvia, who adopted the same strategy as Albania here on Friday by building a very low block and seeing how long it survived.
The fact that is did for so long was not just a testimony to their determination, but also England's bad habit of firing in aimless crosses, while failing to move the ball quickly and decisively in danger areas.
Tuchel kept faith with Rashford on the left, while replacing Phil Foden with West Ham United's Jarrod Bowen on the right, but once again the new head coach would surely have expected more from the wide positions.
The six-point haul was fully expected from Tuchel's first two games against such opposition, and he will be satisfied with two clean sheets, but it will prove a highly valuable exercise in informing him where England must improve if they are to fulfil his single mission - which is to win the 2026 World Cup at the conclusion of his 18-month contract.
