''I feel I'm in a pretty good groove serving right now,'' Roddick said. ''It feels comfortable ... the percentages seem like they're there. And it certainly gives you a decent opportunity when you serve well.''
And Roddick, the 2002 RMKC champion and a two-time Memphis finalist, appears to be on a quiet, determined trek to win an elusive second title on the indoor courts at The Racquet Club. Although Thursday night's victory placed him in the quarterfinals for the eighth time in nine Memphis appearances, he's been, in his evaluation, a too-infrequent finalist.
''I actually look back and feel like I could have played better,'' Roddick said. ''There's not a lot of American tournaments that I've played this many times and have only one win to show for it. I feel like I've definitely left some matches out on the table here.''
''Even though I was down a break, I felt I was playing the better of the two of us,'' Roddick said. ''It's a big difference when you can bounce back and kind of retake control of the match. I thought that was a good sign.''
''To be honest, the year before we didn't have much of an offseason because of the Davis Cup (final),'' Roddick said. ''To have six weeks where you can actually plan workouts on a daily basis and really get out in front of it is something that is rare for us.
''I just took advantage of it. I was able to schedule track workouts and practices and not worry about anything else getting in the way. And I was pretty disciplined about not missing any and doing work on a daily basis and, all of a sudden, six weeks later you see the results.''
"I (could) sense that (Ginepri) was kind of like, 'we both know you're not this good,'" Roddick said. "I wish I could play like that every time."
