Beijing Olympic gold medallist Elena Dementieva dug her own grave to go down to Kateryna Bondarenko of the Ukraine in the second round at the Pan Pacific Open tennis tournament on Tuesday.

The Russian third seed, the champion here in 2006, committed a double fault twice on a break point and once on a match point to lose 2-6, 7-6 (7/3), 1-6 to the 33rd-ranked Bondarenko.
