Scott William Garrelts (born October 30, 1961) is an American former Major League Baseball pitcher who played for the San Francisco Giants from 1982 to 1991. Garrelts's best year as a Giant came during the 1989 season, when he went 14-5 with a 2.28 ERA, leading his team to the World Series against their Bay Area rivals, the Oakland Athletics.

Garrelts attended high school at Buckley Loda High School in Buckley, Illinois.^[1]

Garrelts was the Giants' lone All-Star in 1985, a season in which he led the team in wins and ERA, and had streak of 24 consecutive scoreless innings, all as a reliever. In 1986, he was second on the Giants in wins and strikeouts. Garrelts missed the final month of the 1987 season with a broken finger tip, but still finished second on the Giants in saves, a stat in which he led the team in 1988. He missed a month of the 1989 season with a pulled hamstring. During the season, Garrelts switched from the bullpen to a starting role and led the N.L. in ERA. He was second on the Giants in wins and strikeouts in 1990.

On July 29, 1990, Garrelts took a no-hitter into the ninth inning at home against the Cincinnati Reds, which was broken up by Paul O'Neill, with a two-out single over shortstop Jose Uribe's head.^[2]

While with the Giants, Garrelts and teammates Dave Dravecky, Atlee Hammaker, and Jeff Brantley became known as the "God Squad" because of their strong Christian faith. Foregoing the hard-partying lifestyle of many of their teammates, they preferred to hold Bible studies in their hotel rooms while on the road.^[3]
