Retired vs Kudryavtsev, wonder what happened.
He won the 1st set 7-6 (6), lost the 2nd set 3-6 and then retired in the 3rd at 0-1. He had a medical timeout in the 2nd set.
Edit: It's the shoulder, probably palyed too much lately.
So coming back to Estonia instead of Wolfsburg. Let's hope it's not too serious.
