Yips or the yips is the apparent loss of certain fine motor skills, seemingly without explanation, in one of a number of different sports. The technical term is focal dystonia.

Professional or leading amateur sportsmen affected by the Yips sometimes recover their ability, sometimes compensate by changing technique, or may be forced to abandon their sport at the highest level.

In golf, the yips is a movement disorder known to interfere with putting. The term yips is said to have been popularized by Tommy Armour—a golf champion and later golf teacher—to explain the difficulties that led him to abandon tournament play. In describing the yips, golfers have used terms such as twitches, staggers, jitters and jerks.

The yips affects between one-quarter and one-half of all mature golfers. Researchers at the Mayo Clinic found that 33 percent to 48 percent of all serious golfers have experienced the yips. Golfers who have played for more than 25 years appear to be most prone to the condition. Golfers seriously afflicted by the yips include Bernhard Langer, Ben Hogan, Harry Vardon, and Sam Snead, whose late-career putting was "painful to watch" according to fellow pro golfer Ben Crenshaw.

Eldrick Tont "Tiger" Woods (born December 30, 1975) is an American professional golfer whose achievements to date rank him among the most successful golfers of all time. Formerly the World No. 1, he is the highest-paid professional athlete in the world, having earned an estimated US$90.5 million from winnings and endorsements in 2010.

Woods turned professional in 1996, and by April 1997 he had already won his first major, the 1997 Masters. He first reached the number one position in the world rankings in June 1997. Through the 2000s, Woods was the dominant force in golf, spending 264 weeks from August 1999 to September 2004 and 281 weeks from June 2005 to October 2010 as world number one. From December 2009 to early April 2010, Woods took leave from professional golf to focus on his marriage after he admitted infidelity. His multiple infidelities were revealed by several different women, through many worldwide media sources. This was followed by a loss of form, and his ranking gradually fell to a low of #58 in November 2011. He snapped a career-long winless streak of 107 weeks when he captured the Chevron World Challenge in December 2011. As of April 8, 2012, he is ranked #8.

Jonathan Tyler Lester (born January 7, 1984, in Tacoma, Washington) is an American professional baseball pitcher with the Boston Red Sox. Lester was 7-2 with a 4.76 ERA before and after being diagnosed with lymphoma. Less than two years after being diagnosed with lymphoma, Lester started and won the final game of the 2007 World Series, and in May 2008, pitched a no-hitter against the Kansas City Royals.

Lester attended Bellarmine Prep in Tacoma, Washington, where he was a three-time MVP and three-time All-Area selection. In addition, he was named Gatorade State Player of the Year for Washington in 2000.

The Red Sox drafted Lester in the second round (No. 57 overall) of the 2002 draft and gave him the highest signing bonus of any second-rounder that year, $1 million.

Lester quickly moved through the Red Sox organization, posting an 11–6 record, a league-leading 2.61 ERA and a league-best 163 strikeouts for the AA Portland Sea Dogs in 2005. He was named Eastern League Pitcher of the Year and Red Sox Minor League Pitcher of the Year and was selected as the left-handed pitcher on the Eastern League's year-end All-Star team and on the year-end Topps AA All-Star squad.
