3 1/2 hours in a second round. Lost 7-6 in the third. Then the guy had to play the second seeded who was ranked top 50 in Australia with a 15 minute break. Ouch! Relaxing at changes was real important to help re-focus during the match.
Also, focusing on really stroking through the ball, not just smacking the crap out of it.
Never give up.Never,never,never,never.
