Carlos Lopez was a Mexican outfielder, a right-handed hitter who played three major league seasons: California Angels in 1976, Seattle Mariners in 1977 and Baltimore Orioles in 1978. Born in Mazatlan, Sinaloa, he began his professional career in 1969 with the Aguascalientes Tigres of the Mexican Center League and later played for the Mexico City Tigres, who sold him to the Angels on December 3, 1973. In the California system he hit .295 at Double-A El Paso in 1974 and .327 there in 1975, leading the Texas League in triples. He then batted .350 at Triple-A Salt Lake City in 1976, third in the Pacific Coast League in batting average. Seattle took him in the 1976 expansion draft, and Baltimore acquired him after the 1977 season. His last major league game came on October 1, 1978. In 237 major league games he batted .260 with 12 home runs and 54 RBI. He stole 23 bases.
