A baseball term that describes a left-handed throwing pitcher.
The term "southpaw" can be traced back to the late 19th century. Pitchers would traditionally face west, meaning that their left hand was on the south side of their body. Southpaws are a good match-up for left-handed hitters due to the breaking action of pitches like curveballs and sliders. Left-handed pitchers, much like left-handed people, have always been uncommon in baseball, but most clubs have at least one or two in their stable of pitchers.
