Alexander Zverev completed his dominant week at the Western & Southern Open Sunday by cruising past Andrey Rublev 6-2, 6-3 to lift his fifth ATP Masters 1000 title and become the first German champion in Cincinnati since Boris Becker in 1985. The World No. 5 had never won a match in six previous appearances at the tournament, but produced high-quality tennis all week to back up his Olympic singles gold medal in Tokyo and capture his fourth tour-level trophy of the season.
