Slice Serve
Also known as: saque cortado, cut serve
A Slice Serve in padel is an underarm serve struck with sidespin. As a result, the ball curves in the air and then skids low and wide off the bounce, drawing the receiver out of position.
The slice serve is the most commonly used spin serve in padel. Brushing the right side of the ball (for a right-handed server) during the underarm motion imparts sidespin. This causes the ball to curve away from the receiver or into their body depending on the target. After bouncing, the slice stays low and skids, especially on synthetic turf, making it harder to return cleanly than a flat serve of equal pace. Targets for the slice serve include the wide corner of the service box (pulling the receiver off the court) and the T junction (keeping them guessing between the body and the line).
Brush around the right side of the ball (for right-handed players) as if you are cutting around an apple. This means the feeling is sideways and slightly downward rather than lifting upward through the ball as in a kick serve.
Combine the slice serve with a wide body position to increase the curve angle. This means serve from the extreme right corner of the service zone on the deuce side to maximise the angle the slice creates as it curves away from the receiver.
Example
The server brushes around the outside of the ball and targets the wide corner of the deuce service box. This means the slice curves away from the receiver, who can only defend weakly from outside the court.
Why it matters
The slice serve is the primary first-serve weapon at intermediate and above. SwingVantage detects the curve trajectory from video to confirm sidespin generation.
How it shows up on video
In video, a slice serve shows the racket brushing around the side of the ball during the underarm delivery. This causes the ball to curve in the air. Watch the ball's flight path from above (or from a rear-court angle). This means a sliced serve curves laterally before the bounce. By contrast, a flat serve travels straight. After the bounce, the slice should skid and stay low rather than rising into the body.
Common mistakes
- Brushing too directly across the ball rather than around it, producing a ball that curves slightly but bounces without the skidding component.
- Hitting the slice serve with reduced pace to the point where receivers simply step in and drive it with plenty of time.
- Always slicing to the same target corner, allowing receivers to anticipate and pre-position wide before the serve is struck.
- Losing accuracy on the slice when nervous — the wrist brushing motion is fine enough that pressure causes grip tightening and reduced spin control.
In SwingVantage Motion Lab
Motion Lab detects lateral ball-flight curvature on serves by tracking the ball's horizontal deviation from the direct line between server and target. Greater than 25 cm of lateral deviation before the bounce confirms active sidespin generation consistent with a slice serve.
Related terms
- ServeThe padel serve is an underarm delivery. This means the ball is bounced once and struck at or below waist height into the diagonal service box. This means making placement and net advancement far more important than pace.
- Kick ServeA Kick Serve in padel is an underarm serve struck with topspin. As a result, after bouncing in the service box it accelerates and kicks up or to the side. This makes the return more awkward than a flat serve.
- Body ServeA Body Serve in padel is a serve directed at the receiver's body. This means typically at the hip or shoulder on the dominant side. This means to jam the swing and prevent a clean, aggressive return.
- Serve PlacementServe Placement in padel is the deliberate targeting of specific zones within the service box. This means the T, the wide corner, or the body. This means to create the weakest possible return and set up an easy net volley.
- Service BoxThe Service Box is the rectangular area diagonally opposite the server into which the underarm padel serve must land after one bounce. This means with pace blunted by the walls, placement beats power. This makes slice and kick serves especially effective.
