Blake lost the first four games of the match and was down 3-1 in the second set. He won five games and jumped out to a 4-1 lead in the final set, only to have Kamke rally.
Kamke, playing here for the first time, won four of the next five games to pull even at 5-all. He then won the final five points of the tiebreaker to hand the 32-year-old Blake his eighth loss in nine matches this year.
"I felt great the last two days of practice and I really don't know what happened. Blake said.
"I started slow. Even when I was winning, I felt like I was just scrapping out points and not dictating the way I wanted to. When I'm not doing that, I'm not playing my best and I'm not confident, and when you're not confident in a tiebreaker you're going to miss a couple of balls by centimeters or millimeters.
"I didn't make a lot of first serves in that tiebreaker and didn't give myself the chances I needed to. I can't do that and expect to win out here."
