With a total of seven tie-breaks played in between the men's quarterfinals and women's semifinals, the serve dominated Day Five at the Regions Morgan Keegan Championships and the Cellular South Cup on Friday.

In the ?marquee? match of the day, No. 1 seed Andy Roddick improved to 4-0 against Robby Ginepri with a 7-6(7), 7-6(1) win to advance to the quartefinals. At 4-4 in the first set, Ginepri was able to put pressure on Roddick's serve with three consecutive deep returns that lead to a total of four break points in that game, which Roddick saved with blasting serves. In the tie-break, Roddick won one of the longest rallies in the match at 7-7 and closed out the first set in the next point with a powerful serve.

Both players held serve consistently throughout the second set reaching a second consecutive tie-break, which Roddick easily won 7-1 to claim the victory. With the win, Roddick improves to 13-1 in the year and will now face Kenneth Carlsen for a spot in Sunday's final.

Carlsen advanced with a 7-6(7) 7-5 win over Jan-Michael Gambill. Both players won over 70 percent of their service points in a match that had just four break points. In the first set, only one game lasted to deuce, but Carlsen prevailed despite facing nine aces in the set from Gambill, including the fifth game that Gambill won to love with four straight aces. The second set was similar, until Carlsen faced three break points in the 11th game of the match, saving them all. Gambill, after serving just his second double fault of the match, lost on the only break point he faced all day to drop the match in the 12th game.

No. 2 seed Tommy Haas needed just over an hour to get past Xavier Malisse 6-4 6-3. Haas won 83 percent of his points on serve – losing just one service point in the first set – and did not face a break point in the match. The opening set was decided as Haas broke Malisse in the final game on his only break point of the set. With a break in Malisse’s first service game of the second set, Haas had all the advantage he would need. He will face Max Mirnyi for a spot in Sunday's final.

Mirnyi won 79 percent of his service points in a 7-6(1) 7-6(1) win over Antony Dupuis on Friday. Mirnyi saved all four of the break points he faced in the match while only managing one break chance against Dupuis. Mirnyi fired 18 aces in the match, although only one ace came in the two-tie-breaks. The tie-breaks were one-sided, with the only two points Mirnyi conceded coming on double faults.

On the women's side, Meghann Shaughnessy tied the series 1-1 against No. 7 seed Nicole Vaidisova 7-6(8), 7-6(6). Shaugnessy avanged her previous loss that came in the semifinals of Tashkent last year, where the 15-year-old Czech won 6-1, 5-7, 7-6(1).

No. 1 seed and defending champion Vera Zvonareva played flawless tennis to beat fellow Russian Evgenia Linetskaya 6-4, 6-1 and has now won nine consecutive matches in Memphis.
