In boxing and some other sports, a southpaw stance is where the boxer has their right hand and right foot forward, leading with right jabs, and following with a left crossright hook. It is the normal stance for a left-handed boxer. The corresponding boxing designation for a right-handed boxer is orthodox and is generally a mirror-image of the southpaw stance. In American English, "southpaw" generally refers to a person who is left handed. It is widely regarded that 19th century prizefighter William 'Bendigo' Thompson is credited for introducing the southpaw stance.
Strategy
Left-handed boxers are usually taught to fight in a southpaw stance, but right-handed fighters can also fight in the southpaw stance for many reasons. Fighting in a southpaw stance is believed to give the fighter a strategic advantage because of the tactical and cognitive difficulties of coping with a fighter who moves in a mirror-reverse of the norm. Left-handed fighters are often taught to fight in orthodox stance despite their dominant side being their left, either because of the overriding need to best counter a fighter who uses an orthodox stance, or because of the limited number of trainers who specialize in training the southpaw stance. A skilled right-hander, such as Roy Jones Jr., Terence Crawford or Marvin Hagler, may switch to the left-handed stance to take advantage of the fact that most fighters lack experience against lefties. In addition, a right-hander in southpaw with a powerful left cross obtains an explosively different combination. The converted southpaw may use a right jab followed by a left cross, with the intention of making the opponent slip to the outside of their left side. Then the converted right-hander can simply turn their body left and face their opponent, placing them in orthodox, and follow up with an unexpected right cross. If the southpaw fighter is right-hand dominant with a strong left cross, this puts the opponent in danger of knockout from each punch in the combination, as jabs with the power hand can stun or knock out in heavier weight classes. While rare, the reverse is also true for left-handers; left-hand dominant fighters like Oscar De La Hoya and Miguel Cotto who fight from an orthodox stance give up the so-called "southpaw advantage" strategically, but are gifted with heavier lead hands. Consequently, in MMA if one stands in a southpaw stance, one must train one's cross and left low kick to make it fast, hard and dangerous. While rare, cross-dominant MMA fighters and kickboxers could also benefit from fighting from a southpaw stance.
Previous uses of the term southpaw
The "American Heritage Dictionary of the English Language" cites the conventional wisdom that the word "southpaw" originated "from the practice in baseball of arranging the diamond with the batter facing east to avoid the afternoon sun." Though many claim that the term originated due to the orientation of baseball playing fields in order to keep the sun out of the players' eyes and the resulting alignment of a left-handed pitcher's throwing arm causing the pitcher to have his left hand on the south side of his body, the term had been used decades prior to that to indicate "not-usual".
