Richard Avina Renteria (born December 25, 1961 in Harbor City, California) is currently the bench coach for the San Diego Padres. During his playing career, he was usually called "Rich", but now goes by "Rick".
Renteria is of Mexican American descent. He was drafted by the Pittsburgh Pirates 20th overall in the 1980 Major League Baseball Draft. He was an infielder for the Pirates (1986), Seattle Mariners (1987–88) and Florida Marlins (1993–94). While playing for the Florida Marlins, he was nicknamed "The Secret Weapon" for his versatility on the field and his timely pinch hitting. In five major league seasons, he played in 184 games and had 422 at bats and a .237 batting average.
After his playing career, Renteria has remained in baseball ever since. His first minor league managerial job was in 1998 with the Brevard County Manatees in the Marlins organization. He continued to manage in the Marlins system until 2001. In 2003, he was named the hitting coach for the Lake Elsinore Storm in the Padres organization, and in 2004 he became the Storm's manager. After three seasons with the Storm, in 2007 he was moved up to the Triple-A Portland Beavers.
