Seventh seed Maria Sakkari overcame a 6-1 4-1 deficit and saved four match points to beat top seed Elina Svitolina and reach her second consecutive semifinal in San Jose. After dropping serve five times in her first eight service games, Sakkari got the match back on serve in a seven-deuce ninth game of the second set, in which the Greek saved three match points before breaking Svitolina and then saved one more in the next game before holding serve for 5-5. After winning the second set in a tiebreak, the world No.30 Sakkari dropped serve early in the third set, but recovered from that deficit and never trailed again to progress with a 1-6 7-6(3) 6-3 victory.
