Pitching position
In baseball, there are two legal pitching positions: the windup, and the set. Colloquially, the set is often referred to as "the stretch", although this term actually only refers to one part of the pitching motion when pitching from the set.[1]

Set
A pitcher is in the set when, with the ball, they stand on, or directly in front of—and touching—the pitching rubber, with their toes pointing toward the side (toward
As with the windup, prior to the time of pitch, the pitcher may step toward and throw or feign a throw to a base, subject to the balk rules, or disengage the rubber by stepping back (toward second base) with their pivot foot.
Strengths and weaknesses
Both types of pitching position have their strengths and weaknesses. Compared to the set, the windup has a relatively slower execution, and it is therefore better suited for situations in which there are no
However, some pitchers, particularly relief pitchers, are more comfortable pitching from the set position and thus use it regardless of the situation. Whether a pitcher starts from the windup or the stretch is all about what feels best for their own personal preference. The reason more than half of pitchers start from the windup position is because that type of motion gets a little bit more of a rhythm going before pitching.
Impact
Data analysis indicates that pitch velocity is equivalent whether thrown from the windup or the set position.[2]
Additionally, common wisdom is that the set is less damaging to the connective tissue of a pitcher's arm, but research in this area has been unable to support this hypothesis.[3]
