A separate tip on this site explains how to line up properly when playing from “misaligned” tee boxes. Sometimes, even perfect alignment can be derailed by a swing that follows the direction of the tee or lines in the grass.
For example, say you’re playing a dogleg-right hole where the tee box points down the right side of the fairway. You want to play a fade that starts down the left side, so you line up accordingly. However, the visual cue of the mowing pattern tells your mind to swing in the direction of the grass line. As a result, you take the club back to match that line – in other words, to the inside of your actual target line – and end up hitting the ball right after all.
In these cases, you must be aware of the tendency to swing the way those external cues are aiming you. To fight this, make a couple of practice swings lined up exactly as you will address the ball, and swing with your body’s alignment, looking up at the target on the finish. Making practice swings while looking at the target, instead of the ground, can also help.
If playing a fade against a right-facing tee box, the correct takeaway may feel like it’s outside the intended target line – it’s probably not, and if it is, that’s okay because the ball will start a bit farther left and fade back to the fairway.
The same concept holds true on the through-swing. In the fade example, focus on firing your right side through the shot to ensure that your swing follows the proper path.
