Why Don't More Tennis Players Underarm Serve? The Surprising Reasons Behind a Rare Tactic

It's a play you might see in a movie, a highlight reel, or maybe even a bit of exhibition tennis – the underarm serve. It's that sneaky, low-bouncing shot where a player tosses the ball just a few feet in the air and swings from below. It’s a legitimate serve in tennis, but you rarely see it in professional matches, let alone in your local league. So, the question on many a tennis fan's mind is: why don't more tennis players underarm serve? It seems like an easy way to surprise your opponent, right? The answer is multifaceted, touching on strategy, tradition, physics, and even the perception of the sport.

The Strategic Disadvantage: Less Pace, Less Spin, More Risk

The primary reason the underarm serve isn't a staple of tennis strategy lies in its inherent limitations compared to a traditional overhead serve.

Lack of Pace: A conventional overhead serve generates significant racquet head speed due to the downward motion and the physics of a high toss. This translates to a much faster ball speed. An underarm serve, by its nature, has a much lower ceiling for speed. Professional players rely on the sheer velocity of their serves to win free points, force weak returns, or set up aggressive follow-up shots. An underarm serve simply doesn't have the "oomph" to achieve this.
Limited Spin Potential: While it's possible to impart some spin on an underarm serve, it's far less effective and versatile than the topspin, slice, and kick serves that professional players master. These spins are crucial for controlling the ball's trajectory, making it bounce unpredictably, and keeping it within the lines. An underarm serve often results in a flatter, more predictable bounce, which is easier for an opponent to attack.
Predictable Trajectory: The arc of an underarm serve is generally much lower and flatter than an overhead serve. This makes it easier for an experienced player to read the ball's path and adjust their position accordingly. Instead of reacting to a fast-moving ball dropping from above, they're often looking at a ball coming from a lower, more consistent angle.
Higher Risk of Errors: Executing an underarm serve effectively requires precision. A poorly executed underarm serve can land in the net, go long, or sit up for an easy put-away for the opponent. The margin for error is often smaller when trying to get the ball over the net with sufficient pace and placement from a low position.

The Element of Surprise: A Double-Edged Sword

The allure of the underarm serve, especially in professional tennis, often lies in its surprise factor. Players might consider it when their opponent is standing far behind the baseline, anticipating a powerful serve. However, this element of surprise is often fleeting and can backfire.

"The biggest reason is that it’s a less effective weapon. In professional tennis, you want your serve to be a weapon. An underarm serve is rarely going to be a weapon. It's more of a surprise, and if your opponent is ready for it, it’s usually a bad shot for the server."

If an opponent is indeed caught off guard, the underarm serve might win a point. But the cost of failing to surprise them, or them recovering quickly, is a weak serve that gives them a significant advantage. Professional players are incredibly adept at reading serves and reacting to different speeds and spins. They can often adjust to an underarm serve and exploit its weaknesses.

The Psychological and Societal Factors

Beyond the purely technical aspects, there are also psychological and societal influences at play that discourage the widespread use of the underarm serve.

Perception of "Unfair Play": For a long time, the underarm serve has been seen by some as a bit cheeky or even unsportsmanlike, especially when used against a player who is clearly struggling or injured. While it's a legal shot, it carries a certain connotation that can make players hesitant to use it for fear of being labeled as disrespectful. This perception is slowly changing, especially after Nick Kyrgios's successful use of the tactic.
Tradition and Coaching: Tennis has a rich tradition, and the emphasis in coaching has always been on developing powerful and effective overhead serves. The underarm serve is rarely a focus in standard coaching methods. Players are trained from a young age to master the overhead motion, and deviating from that can feel like a step backward for some.
The "Showmanship" Factor: When an underarm serve is used successfully in a high-stakes match, it often becomes a talking point and is perceived as a display of exceptional skill and nerve. However, this is the exception, not the rule. For most players, the risk of looking foolish or losing a point easily outweighs the potential reward of a surprising winner.

When Does It Make Sense? Niche Scenarios

Despite the general disadvantages, there are indeed situations where an underarm serve can be a viable option, albeit a rare one:

Against a Deep Receiver: As mentioned, if an opponent consistently stands so far behind the baseline that they are practically in the stands, an underarm serve can be an effective way to catch them off guard and force them to sprint forward.
When Injured or Struggling: In rare instances, a player who is physically unable to generate pace on an overhead serve due to injury might resort to an underarm serve to keep the ball in play. This is more about survival than strategy.
Exhibition Matches and Lower Levels: In casual matches, friendly games, or exhibition events where the focus is on entertainment, the underarm serve can be a fun and surprising tactic to employ.

The underarm serve remains a fascinating part of tennis, a legal shot that offers a glimpse into the strategic mind of a player. However, its inherent limitations in pace, spin, and predictability, combined with a lingering perception of unsportsmanlike conduct, ensure it will likely remain a niche tactic rather than a mainstream strategy in the world of professional tennis.

Frequently Asked Questions (FAQ)

Q: How can a tennis player make an underarm serve effective?

A: To make an underarm serve more effective, a player needs to focus on placement and deception. Aiming for the corners of the service box or the body of the opponent can make it difficult to return. Imparting some slice or topspin can also make the ball bounce unpredictably, but this is challenging from an underhand motion.

Q: Why is the underarm serve considered unsportsmanlike by some?

A: Historically, the underarm serve has been seen as a tactic used to exploit a weaker opponent, particularly if they were struggling physically or mentally. It can be perceived as a "cheap" way to win a point rather than through skillful rallying or powerful serving. However, this perception is evolving.

Q: Has the underarm serve ever been a common tactic in tennis?

A: In the very early days of tennis, before the overhead serve became dominant, serves were generally flatter and less powerful. However, as the game evolved and players developed the overhead motion, the underarm serve became increasingly rare as the overhead served proved far more advantageous.

Q: Are there any famous players who use the underarm serve regularly?

A: While not regular, Nick Kyrgios is probably the most well-known modern player to have successfully and strategically employed the underarm serve. His use of it has brought it back into the discussion of viable tactics, though it's still an exception rather than a rule.
