These photographs feature the home run baseball hit by Kansan Gil Carter on August 11, 1959 while playing for the minor league Carlsbad Potashers in New Mexico. The official scorer put the home run distance at 650 feet. However, estimates based on aerial photograph measurements were reported at 700-733 feet, which would make it the longest home run in baseball history. The opposing pitcher was Wayne Schaper of the Odessa Dodgers. Carter was an outfielder for the Potashers in 1958-59, and the St. Cloud Rox in 1960. In his three years in the minors, Carter batted for a .264 average, hit 72 home runs, and had 266 RBIs. He led the Sophomore League in home runs in 1959, with 34; he was named to the Northern League All-Star Team in 1960. In the early 1960s, Carter also was the starting left fielder for the Wichita Rapid Transit Dreamliners, a team that won national semi-pro baseball championships in 1962 and 1963. His national tournament performance (.484 batting average and six home runs) earned him a spot on the National Baseball Congress All-American Team in 1962. Carter was born and raised in Topeka. He lived in Wichita for nearly four decades before returning to Topeka in 2000. Digital images of the baseball were created through a joint project sponsored by the Kansas Historical Society and the Shawnee County Baseball Hall of Fame.
