Wozniacki broke Osaka in five of the six games in which she held a break opportunity in the Tokyo final. In all five of the games she won, Wozniacki won on the first break point she had.
SAP Coaches View shows that Wozniacki was particularly aggressive facing Osaka's second serve. The former World No. 1 returned 92% of Osaka's second serves from inside the baseline. That helped her to win 66% of the second-serve points she faced.
An interesting contrast is to see how Wozniacki used her second serve. Looking at Osaka's service return positioning, it is apparent that Wozniacki was intent on keeping her second serves out wide on both sides of the court.
Based on these views from SAP Coaches View, the patterns of how Wozniacki dictated play on second serve points are apparent.
The SAP Coaches View combines scoring information direct from the chair umpire with tracking data from HawkEye to allow for an in depth look at five different aspects of a match. Each tracking option can be filtered to narrow the focus to specific situations within a match, such as break points. This information is available directly to coaches in real-time during a match on their SAP tablet and also available to them online after matches.
"Return of serve" tracking shows where each service return was struck, differentiating between first and second serves, with an emphasis on how many serves are returned from inside the baseline. This data can be filtered by a particular score.
Wozniacki's consistency, particularly on second-serve points, helped the veteran secure the title against her teenaged opponent Sunday in Tokyo.
