Steven Ray Crawford (born April 29, 1958) is a former pitcher in Major League Baseball who played for two teams from 1980 through 1991.

One of his teammates, Michael Moore, called Crawford “Shag” because of his bushy long hair and mustache, and the nickname stuck.

A versatile hard-thrower, Crawford filled various relief roles coming out from the bullpen, as a closer or middle reliever, serving as an emergency starter as well.

He reached the majors in 1980 with the Boston Red Sox, spending seven years with them before moving to the Kansas City Royals (1989–91).

His most productive season came in 1985 with the Red Sox, when he set career-numbers in wins (6), saves (12), strikeouts (58) and innings pitched (91.0).
