By the numbers: Eala holds off Valentova to reach seventh quarterfinal of season

No. 2 seed Alexandra Eala held off a spirited challenge from fellow teenager Tereza Valentova to win in straight sets and advance to the quarterfinals of the Prudential Hong Kong Open on Thursday.

Eala made a strong start, breaking early to race to a 3-0 lead before Valentova fought back to level the opening set at 4-4. Eala saved three break points in a crucial ninth game before breaking her opponent at love to claim the set 6-4.

In the second set, Valentova struck first, breaking to take a 4-2 lead, but Eala battled back to level the score at 5-5 and force a tiebreak.

Eala raced to a 5-0 lead in the tiebreak before Valentova mounted another comeback, saving three match points. However, the Filipino held her nerve to complete a 6-4, 7-6 (9-7) victory in one hour, 54 minutes.
