Learn the overhead smash: footwork, contact above the hitting shoulder and safe placement, with milestones, common mistakes and an honest note on shoulder load.
The honest answer: the overhead, short smash, is the shot with which you hammer a high ball over your head with a throwing motion into the opponent's court, usually at the net. The British governing body describes it like this: contact above the head in the 12 o'clock position, racket path like an overarm throw [1]. That sounds like half a serve, but it is harder because you do not toss the ball yourself, you have to catch up with it above your head.
How important is it? Rare, but often decisive. In 21 women's doubles matches at three Grand Slam tournaments, the overhead ended 5.2% of points, about one in twenty [2]. If you stand at the net and cannot cash in on your opponent's lob, you give away exactly these points. Overall, 36.1% of points ended in the net zone [2].
How hard is it really? The technique takes one or two sessions to learn, while footwork and timing take much longer, expect several weeks of regular practice (experience value). An honest note: I found no study specifically on smash technique in recreational players. Technique cues come from governing-body material [1], and shoulder load is classified below as a transfer from the serve.
As soon as you recognise the high ball, you turn sideways to the net, raise your hitting arm and point at the ball with your free hand. The governing-body materials say exactly that: track the ball with the non-hitting hand [1]. Milestone: on the side video, shoulder turn and free hand are clearly visible before the ball reaches its highest point.
Do not run backwards, use sideways adjustment steps (practice). Running backwards tips you back, side steps keep your shoulder turned to the net. Drill: your partner throws high balls over your head, you catch them with your free hand above your hitting shoulder. Milestone: you catch 8 out of 10 balls without running a single step backwards.
Hit the ball high in the 12 o'clock position [1], above your hitting shoulder and slightly in front of your body (practice). The motion is an overarm throw, like the serve [1]. The ball does not come from your hand but falls from the air, so you decide the contact point with your feet, not with your arm. Milestone: you hit 8 out of 10 fed balls cleanly in the middle of the racket.
Play the first 10 smashes into the middle of the court, not for pace. Then switch to targets, first cross-court, then down the line. Milestone: 7 out of 10 smashes into the opponent's court. In the governing body's practice format your partner lobs, you smash and the point then continues [1].
After the shot, move straight back into the volley position [1]. Your opponent can still return the ball. Drill: your partner lobs, you smash, the point is played out. Milestone: 5 points in a row in which you are back at the front after every smash.
The smash is rare, but it is an overhead shot and your shoulder carries the load. I found no direct study on smash shoulder loads. As a transfer from the serve: a meta-analysis lists rotation strength of the hitting shoulder, internal rotation range of motion, weekly tennis volume, age and body measures as risk factors for injury in the serve [3]. The rotator cuff reaches peak activity of 40 to 113% of maximum voluntary contraction in the serve and volley [6]. A review of arm injuries in tennis sees overuse as the most common cause and names a lot of tennis, fatigue and disturbed shoulder blade movement (dyskinesis) as risk factors, but the study quality is moderate to low [4]. For shoulder injuries in overhead sports, the evidence for prevention is thin overall [5]. For you that means: raise the number of smashes slowly, warm up the shoulder and stop if it hurts. In doubles, call "mine" to avoid collisions. This guide explains and motivates, it does not replace supervised training.
Read the lob before you run. The governing body names five characteristics you read off the incoming ball: height, depth, direction, speed and spin [1]. On a lob, height and depth matter most: if the ball drops in front of you, you move forward and smash; if it flies deep behind you, you decide beforehand whether to play it after the bounce or run back. This decision before the first step makes the difference (practice).
The overhead, also called smash, is a shot at high balls above the head with a throwing motion [1]. You hit the ball in the 12 o'clock position high above your hitting shoulder and mostly play it as a point-winning shot.
High above the head in the 12 o'clock position [1]. In practice it is above the hitting shoulder and slightly in front of the body. What matters is that you reach the contact point with your feet, not with your arm.
Rarely. In Grand Slam women's doubles it ended 5.2% of points [2]. I found no numbers for other levels or for singles. It is still worth learning, because it lets you cash in on exactly the balls your opponent offers.
Mostly it is the feet, not the arm. If you run backwards, you stand crooked at the contact point and hit too low. Try sideways adjustment steps and the free hand pointing at the ball [1].
It is an overhead shot, and for the serve it is known that high load and factors such as shoulder strength and mobility are linked to injury [3]. I found nothing reliable on smash data. Raise the number of smashes slowly and warm up the shoulder.
