Richard William Tidrow (born May 14, 1947) is a former Major League Baseball player for the Cleveland Indians, New York Yankees, Chicago Cubs, Chicago White Sox, and New York Mets from 1972 to 1984.
He was primarily known as a setup man, or pitcher before the closer; however, on occasion he would also start games.
His best seasons were with the Yankees when he helped the team to two World Series championships in 1977 and 1978, beating the Los Angeles Dodgers twice in a row.
He was traded the following season to the Cubs for Ray Burris.
He acquired his nickname, "Dirt", while playing for the Yankees, for his somewhat unkempt appearance and his tendency to get his uniform shirt dirty even before the start of a game.
His high kick and sidearm delivery anticipated the style of Dennis Eckersley.
Tidrow joined the San Francisco Giants in 1994, serving two years as Major League scout for the American League before becoming Special Assistant to the General Manager in 1996.
Since being promoted to Director of Player Personnel in 1997, he, along with general manager Brian Sabean, was in charge of building a ballclub which appeared in four World Series, including three Championships (2010, 2012 and 2014) within a span of five seasons.
He oversaw a farm system that produced Tim Lincecum, Matt Cain, Madison Bumgarner, Sergio Romo, Pablo Sandoval and Buster Posey.
Tidrow's current title is Senior Vice President of Player Personnel.
