Frances Tiafoe (*98 / USA) – 1st service in practice – 3 of 4 – follow through 1 = targeted pronation, which looks very nice, but the right hip doesn’t seem to get fully involved and the hitting (right) shoulder didn’t come much to the front, also the left palm seem to stay open and far in the front for  a bit too long – 2015 US.Open – NYC

Andy Roddick (*82 / USA) – 1st service in a match – follow through 1 = targeted pronation – Andy has almost the same body parameters like Frances, but he seems to integrate the body energy into the stroke more – his right hip and right shoulder go more to the front – already 3 years later Andy won the 2003 US.Open – 2000 Junior French Open – Paris / France

Frances Tiafoe (*98 / USA) vs.  John Isner (*85 / USA) – service speed comparisons around the middle of their epic 5-set match in the 1st round of the 2016 US.Open – it’s surely tough to measure up to John Isner, but mainly the 24 mph difference in the 2nd service has surely played quite a role –  by the way, they both clocked their fastest service at 142 mph during this event – NYC

Frances Tiafoe (*98 / USA) – 1st service in the match – 1 of 3 – toss – the arch in the low-back area (=hyperlordosis – red arrow) might be part of the mentioned limited hip integration and could also lead to several health issues in both low-back as well as shoulder area after years – 2016 US.Open – NYC

Frances Tiafoe (*98 / USA) – 2nd service-topspin in the match – 2 of 2 – end of follow through 1 – right hip and shoulder stay significantly back, this might be the main reason why the 2nd service is rather slower, left arm far in the front can also have rather slowing effect – 2016 US.Open – NYC
