SINGAPORE - A more targeted approach on her serve led to better results for Agnieszka Radwanska in her 7-6(1) 6-3 win over Garbiñe Muguruza in the White Group round-robin match at the 2016 BNP Paribas WTA Finals Singapore presented by SC Global.

Radwanska's service numbers were improved compared to her opening match in Singapore, a three-set loss to Svetlana Kuznetsova. On Wednesday, Radwanska won 61% of points on serve in the victory, compared to 54% in Monday's loss.

The difference was particularly noticeable on first serves, as she won 72% against Muguruza, up from 57% against Kuznetsova. For the season, Radwanska has won 66% of her first-serve points.

SAP Coaches View technology helps show how Radwanska was more successful on her serve. Looking at her service tracking, it is evident that Radwanska went into the body of Muguruza, particularly on the deuce court.

Against Kuznetsova (see image above), Radwanska seldom went into the body. On the deuce court, she hit 10% of first serves and 5% of second serves into the body. She won just 9% of points off body serves in the deuce court.

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.

"Service" tracking shows the landing point for all serves. The display differentiates between first serves, second serves and aces. Additional data on the screen shows the percentage of overall service points won as well as looking specifically at first and second serves. It can also be narrowed to show the performance on particular points in the match, such as break points.

Radwanska will need her serve to once again be effective when she plays a must-win round-robin finale against Karolina Pliskova on Friday.
