Kayla Day – Solid service 3.0

As a wild-card entry, young Kayla Day (*99 / USA) have had a great run at the 2017 Indian Wells tournament. Here she won 2 main draw rounds (both matches against WTA top 100 players) to later narrowly lose only in a tough 3 set match against WTA #7 Garbine Muguruza (ESP). Left-handed Californian Kayla, daughter of a Czech mother and an American father, is former #1 in the Junior ITF rankings and 2016 Junior US.Open Champion. Her forehand and service can be considered as her biggest weapons.

The photos shown below are documenting Kayla’s service during the 2015 Orange Bowl, where she narrowly lost in a rainy and thus a couple of times interrupted finals to Bianca Andreescu (*00 / CAN). The very well developed essential elements of an efficient body energy driven service (=Service 3.0) are here mainly a well-controlled (stable) toss, excellent eye control of the ball, a good build-up of a tension in the body and a sound understanding of the targeted pronation channeling the stored body energy against the target in the first part of the follow through. Such a solid Service 3.0 is an excellent base for further growth and shows that good developmental technical work on the service was done with Kayla in the past. Just the quite big glenohumeral angle, mostly well above 130° (up to 110° is considered as safe for the shoulder) can be considered as a certain risk for the future.

To document that the practically perfect execution of certain elements was not by case, the key moments around the targeted pronation are shown several times.
