Head to heads are 1-1. They last met in August 2014 at the US Open. Ebden won in straight sets. Kamke also won on a hard court in 2011 in Canada. He won in 3 sets.
Better overall results from Ebden this year.

Kamke has raised his level this week. His 2 wins this week were his first ATP main draw wins on grass since Eastbourne in June 2014. He has only been broken 3 times in 2 matches this week.
Ebden has done well for me this week and I am going with him to win again today but I think it will be a very close match. The value is on Kamke at the start.
Back Ebden if he loses set 1. Backing both on serve is an option
