The yips are involuntary muscle spasms, jerks, or freezing that strike athletes during fine motor tasks they’ve performed thousands of times before. A golfer’s hands twitch mid-putt, a baseball player suddenly can’t make a routine throw, a darts player freezes at the release point. The condition sits on a spectrum between a neurological problem (focal dystonia) and a psychological one (performance anxiety), and in many cases, both are happening at once.
How the Yips Feel and Look
The most recognizable symptom is an involuntary wrist spasm, but the yips can also show up as tremors, twitches, or a sudden inability to release the ball or follow through on a swing. In golf, where the condition is most studied, it typically hits during putting or chipping, the moments requiring the most delicate touch. In baseball, it tends to surface on routine throws across the diamond. In cricket, darts, and archery, the pattern is similar: a simple, well-practiced motion suddenly becomes impossible to execute.
What makes the yips different from a normal bad day is that the athlete isn’t just performing poorly. Their body is actively working against them. The muscles fire at the wrong time or lock up entirely, and conscious effort to correct the problem usually makes it worse.
What Causes Them
For some athletes, the yips are a form of focal dystonia, a condition where involuntary muscle contractions happen during one specific task. It’s closely related to overuse of a particular set of muscles, similar to writer’s cramp. Years of repeating the same precise motion can essentially rewire the brain’s motor pathways in ways that produce unwanted movement.
For others, the root is psychological. Stress and anxiety activate the body’s fight-or-flight response, which can disrupt the deeply ingrained motor patterns that make athletic movements feel automatic. When an athlete starts consciously thinking about a motion that should be unconscious, the result can look identical to a neurological problem: jerky, hesitant, uncontrolled.
Most cases involve both elements feeding each other. An athlete experiences a few bad outcomes, develops anxiety about repeating them, and the anxiety triggers more involuntary spasms. While most cases have a psychological basis, researchers estimate that a small percentage of athletes have a genuine neurological disorder, either a tremor or dystonia, driving their symptoms.
How Common Are They
The yips are far more prevalent than most people realize. Studies of professional golfers have found that between 20 and 48 percent of elite players experience the yips at some point in their careers, with a mean prevalence around 35 percent. The odds increase with experience and age, peaking in the 50 to 64 age group. This makes sense given the overuse mechanism: the more years you’ve repeated a motion, the more opportunity your brain has to develop a faulty pattern. Higher predisposition to anxiety also correlates with higher rates of the yips.
Athletes Whose Careers Were Changed
Some of the most dramatic examples come from baseball. Rick Ankiel was a promising young pitcher for the St. Louis Cardinals who suddenly lost the ability to throw strikes during the 2000 playoffs, uncorking wild pitch after wild pitch on national television. He eventually abandoned pitching entirely, reinvented himself as an outfielder, and played until 2013, finishing with 76 career home runs. Steve Blass, a World Series hero for the Pittsburgh Pirates, developed a similar inability to control his pitches and retired in 1974, never recovering.
Chuck Knoblauch, a Gold Glove second baseman for the New York Yankees, began making errant throws to first base on routine grounders. He was eventually moved to the outfield and designated hitter for his final two seasons. Steve Sax had the same problem at second base for the Dodgers but represents a rarer outcome: he fully recovered and went on to post the highest fielding percentage among second basemen in 1989.
NBA player Nick Anderson of the Orlando Magic missed four consecutive free throws in a crucial moment of the 1995 NBA Finals. His free throw percentage cratered to around 40 percent in the following seasons, and his career never fully recovered.
The Yips vs. the Twisties
When Simone Biles withdrew from events at the 2021 Olympics, the public learned about “the twisties,” a phenomenon where gymnasts lose their sense of body position mid-air. They spin too many or too few times, which at elite levels can be genuinely dangerous. The twisties and the yips share an underlying mechanism: external stress disrupts automated motor patterns, causing the athlete to lose control of movements that were once effortless.
The key difference is context. The yips affect fine motor skills in relatively low-speed situations like putting, throwing, or releasing a dart. The twisties affect whole-body spatial awareness during high-speed acrobatics. Researchers currently can’t study the twisties directly because tracking brain activity or muscle movements during a backflip is beyond available technology, so less is known about the precise mechanism compared to the yips.
How Athletes Manage and Recover
There’s no single cure, but treatment typically targets whichever end of the spectrum is most involved.
On the psychological side, cognitive behavioral approaches have shown promise. One documented intervention combined work with a sport psychologist and a golf coach over 10 hours, focusing on five core techniques: goal setting, pre-performance routines, mental rehearsal, centering (a way of grounding attention in the body), and instructional self-talk. A key element was challenging irrational beliefs, like catastrophic worrying about letting a playing partner down. The psychologist and coach also normalized the experience by sharing their own stories of similar difficulties, which helped reduce the shame that often intensifies the problem.
One of the most practical tools is a structured pre-performance routine that redirects attention away from the feared movement. In golf, this might look like shuffling the feet to feel leg tension, taking practice swings focused on arm sensation, glancing at the target between each step, and consciously relaxing the dominant hand before striking the ball. The goal is to replace anxious internal monitoring with a repeatable external focus.
Equipment and Technique Changes
Many golfers find relief by changing their grip or putting style to break the association with the old motor pattern. Switching to a lead-hand-low grip (where the non-dominant hand is lower on the club) provides more stability and reduces the jittery stroke that characterizes the yips. Practicing with only the trail hand can re-engage a more instinctive, athletic feel. Some players train themselves to look at the hole rather than the ball while putting, shifting focus from mechanics to the target, similar to how you naturally look at a basket when shooting or at a friend when tossing them your keys.
Rhythm counting is another technique that works by giving the conscious mind something to do besides worrying. Counting “one, two, and, three” through the stroke imposes a smooth tempo and crowds out the anxious thoughts that trigger spasms.
Medical Approaches
When the yips involve clear dystonia or cramping, injections that temporarily relax the overactive muscles have been used. For the anxiety component, medications that lower heart rate and reduce physical symptoms of nervousness have been prescribed off-label. Neither approach has FDA approval specifically for the yips, and both treat symptoms rather than the underlying cause.
The most important thing to understand about recovery is that it varies enormously. Some athletes, like Steve Sax, work through it and return to full performance. Others, like Steve Blass, never recover. The athletes who fare best tend to combine physical changes (new grip, new routine) with psychological work that addresses the anxiety loop, rather than relying on willpower alone to push through involuntary muscle behavior.
