Germany's Alexander Zverev dominated Japan's Kei Nishikori 6-3, 6-4 Saturday in a showdown of top-10 rivals to reach the ATP and WTA Citi Open final against South Africa's Kevin Anderson. Zverev, ranked a career-best eighth this week, dropped only seven points on his serve and never faced a break point in the 63-minute affair, extending ninth-ranked Nishikori's ATP title drought to 30 events over 18 months. The 20-year-old from Hamburg will try for his fifth career title and fourth of the year Sunday against 45th-ranked Anderson, who ousted 19th-ranked American Jack Sock 6-3, 6-4 on the Washington hardcourts.
