Kayla Day edges Elvina Kalieva 7-6 6-4 in Guadalajara

Kayla Day came through an all-American opener at the WTA 1000 in Guadalajara, holding off Elvina Kalieva 7-6, 6-4 in a tight straight-setter decided by the finest margins. Day's serve gave her the platform: she landed 63.2% of her first deliveries and won 71.6% of those points, striking seven aces despite seven double faults. Kalieva actually edged the efficiency battle behind her first ball, winning 74.5% of those points and 47.6% behind her second to Day's 41.0%, but she found the court with only 52.8% of her first serves. That shortfall left her exposed, and Day reached the second round.
