The Japanese, who is ranked 108th in the world, took an early lead after breaking Björklund's serve in the first set, but the Swede managed to turn the deficit around and won the set.

Doi, who won in Båstad in 2019, then equalized to 1-1 in sets but then Björklund was clearly the strongest in third. 

- I'm just super happy right now, the first match is never easy, says Björklund, in 125th place in the world rankings, about the victory.

She is not completely satisfied with her performance - the transition from grass to gravel means a change in the movement schedule and there she believes she can still get better.

But Björklund also states:

- When you meet good opponents, it is like a tug of war all the time, then it is rarely a "perfect performance".

Björklund meets Spanish Rebeka Masarova, ranked 146th, next.

Rebecca Peterson, Sweden's best player in the women's player with her 96th place in the world ranking, easily advanced to the second round after 2-0 in sets against Norwegian Malene Helgo, ranked 348th in the world.
