Alexandra Eala capped her giant-killing run at the Washington Open with a 4-6, 6-4, 6-0 victory over top-seeded Jessica Pegula on Monday to become the first player from the Philippines to win a WTA title.Eala, now ranked world No 20, overpowered Pegula over the final two sets as play resumed in the final, suspended after lengthy weather delays on Sunday.The 21-year-old left-hander produced a rock-solid service display and an impressive array of winners to deny world No 3 Pegula a 12th career title and a third this year.She won the last nine games of the contest, surrendering just eight points in the third set.“Just pure happiness,” Eala said of her first title, which comes after she agonisingly failed to convert four championship points in her only prior final at Eastbourne last year.“Oh my gosh, winning a [WTA] 500, it’s insane. It’s an incredible milestone for me,” she added.
