The facts

The victory put the 29-year-old German into the quarterfinals of the Erste Bank Open. It was a second-round match, not the tournament final. ^[1][2]
Zverev will become the 30th man to hold the ATP No. 1 ranking and the first German since Boris Becker in 1991. ^[1][2]
He had already secured the year-end No. 1 position earlier in October. The new milestone is the guaranteed date of his first ascent to the weekly top ranking. ^[2]
