My partner played really well and I played very inconsistently. Other than that no other explanation needs to be made.
The first set was a bit closer than it seems with several game points for me in vain. Clinching the point at 40-0 or 40-15 makes all the difference to the score.
In the second set, I started the set trying to slow down the pace of the game. It was initially successful with me going up 2-0. Then I guess my partner figured out my strategy and countered it well winning the next 5 games to go up 5-2. I then started to swing freely to win another consolation game. The next game was won and the game was over.
