Down-the-Line Shot
Also known as: DTL, line shot, down the line
A down-the-line shot travels parallel to the nearest sideline. It changes a crosscourt rally's direction to create a sharper angle or exploit an open court.
The down-the-line shot is a direction-change weapon. It breaks a crosscourt rally pattern by sending the ball along the sideline. That forces the opponent to cover the width of the court they vacated. The sideline is shorter than the diagonal, and the net is higher near the posts. So down-the-line shots carry more risk, demanding precise swing adjustment and better timing than crosscourt shots. The shot is most effective when the opponent is stretched wide to one side, creating a large open court on the other. The backhand down-the-line is often considered more difficult than the forehand version because the swing direction feels counterintuitive. Elite players disguise down-the-line shots by holding shoulder rotation until the last moment.
The technical adjustment required for a down-the-line shot from a crosscourt rally is often underestimated. The swing path must change direction while the mechanics of the stroke remain identical. The racquet face and swing path must both redirect without the player resorting to a pushed or slapped motion. The most reliable down-the-line technique is to contact the ball slightly later than on a crosscourt forehand (farther back relative to the front foot). Swing through at the same pace, and let the contact point shift naturally redirect the ball along the line, rather than consciously steering it.
Tactically, the down-the-line is most powerful when used sparingly in a crosscourt rally pattern. An opponent who has adjusted position to expect crosscourt is caught moving the wrong way when the line shot comes. Players who attempt the line on every second or third shot become predictable. The art is using it as a surprise change of direction precisely when the opponent's positioning is most committed to the crosscourt side. That is usually two or three shots into a consistent crosscourt exchange.
Pick a specific target on the down-the-line side of the court before the shot starts, then focus on contacting the ball slightly later (further behind the ideal forehand contact point) to naturally redirect the ball along the line.
Disguise your down-the-line by holding the shoulder rotation longer than usual. The longer you delay the shoulder turn, the later the opponent reads the direction change.
Example
Pinned in the backhand corner, the player changes direction with a flat backhand down the line, catching the opponent moving the wrong way and winning the point outright.
Why it matters
Knowing when to go down the line separates tactical players from pattern players. Motion Lab estimates your swing direction and whether contact is late. But it does not see where the ball goes. As a result, check your misses on video.
How it shows up on video
On video, check the racquet face and the direction the ball leaves the strings relative to the sideline. Errors show up as the face opening toward the crosscourt target mid-swing, or the swing path drifting outward rather than staying on line, both producing a ball that leaks wide or mid-court.
Common mistakes
- Telegraphing the down-the-line early by rotating the shoulders toward the sideline during the backswing
- Opening the racquet face through contact, sending the ball wide of the sideline rather than along it
- Attempting the down-the-line from a defensive position with insufficient time to change direction cleanly
- Failing to adjust footwork for the changed swing path, producing a body-jammed contact

Motion Lab estimates your swing-path direction and whether your contact is late. Both can cause a down-the-line miss. It does not measure racquet-face angle, so pause your video at contact to check the face.
Frequently asked questions
When is the right moment to go down the line?
Go down the line when the opponent is clearly positioned for a crosscourt reply, when you have a short ball you can take early, or when you're approaching the net and want to use the opponent's momentum against them.
Related terms
- Crosscourt ShotA crosscourt shot travels diagonally across the net to the opposite side of the court. It uses the longest available distance and the lowest part of the net.
- ForehandThe forehand is a groundstroke hit on the dominant-hand side, swinging across the body. It is a player's most natural and usually most powerful shot.
- BackhandThe backhand is a groundstroke hit on the non-dominant side of the body, played either with one hand or two, and can be struck flat, with topspin, or as a slice.
- Approach ShotAn approach shot is struck off a short ball as the player moves toward the net, designed to put the opponent under pressure while allowing time to close into a volley position.
- Shot SelectionShot selection is the real-time choice of shot type, direction, pace, and spin. It depends on court position, ball height, opponent location, and score.
- Passing ShotA passing shot is hit by the baseline player when the opponent has approached the net, aiming to place the ball past the net player through an angle or pace that cannot be volleyed.
