Michael Grant Marshall was an American professional baseball pitcher. He played in Major League Baseball (MLB) in 1967 and from 1969 through 1981 for nine different teams. Marshall won the National League Cy Young Award in 1974 as a Los Angeles Dodger and was a two-time All-Star selection. He was the first relief pitcher to receive the Cy Young Award.

The Sporting News Reliever of the Year Award was an annual award presented to the best relief pitcher in each league in Major League Baseball (MLB). It was established in 1960 by The Sporting News (TSN) as the Fireman of the Year Award. At the time, no reliever had ever received a Cy Young Award vote. The Fireman of the Year Award originally recognized the reliever with the most combined saves and wins in each league in MLB. The magazine had started publishing the then-unofficial save statistic that same year. Later, a save was worth two points compared to one for a win in determining the winner. In 2001 the award was chosen based on consensus from TSN editors, and it was renamed to Reliever of the Year Award. The award was last issued in 2010 before being discontinued.
