Luis Ernesto Aparicio Montiel (born April 29, 1934), nicknamed "Little Louie", is a Venezuelan former professional baseball player. He played in Major League Baseball (MLB) as a shortstop from 1956 to 1973 for three American League (AL) teams, most prominently as a member of the Chicago White Sox. During his ten seasons with the team, he became known for his exceptional defensive and base-stealing skills. A 13-time All-Star,, he made an immediate impact with the team, winning the Rookie of the Year Award in 1956 after leading the league in stolen bases and leading AL shortstops in putouts and assists; he was the first Latin American player to win the award.
From 1956 to 1962, Aparicio and second baseman Nellie Fox formed one of the most revered double play duos in major league history. As the team's leadoff hitter and defensive star, he provided a spark to the "Go-Go" White Sox, helping to lead them to their first pennant in 40 years in 1959, finishing second to Fox in the Most Valuable Player (MVP) voting. His 56 stolen bases that season were more than twice as many as any other major league player, and the most by any player in 16 years; he tied the White Sox club record, with the mark not being surpassed until 1983. Aparicio led the AL in stolen bases a record nine consecutive seasons to begin his career, becoming the first player since the 1920s to steal 50 bases four times. Traded to the Baltimore Orioles before the 1963 season, he set a franchise record with 57 steals in 1964, then played a major role in helping the club to its first World Series title in 1966. Aparicio won nine Gold Glove Awards, setting a league record since matched only by Omar Vizquel; he led the AL in fielding percentage eight consecutive years, and in assists seven times, putouts four times and double plays twice, and in 1960 became the first AL shortstop in 25 years to post 550 assists.
When he retired, Aparicio ranked second to Ty Cobb in AL history in career at bats (10,230), fifth in games played (2,599) and seventh in singles (2,108); his 506 stolen bases trailed only Cobb and Eddie Collins among AL players. He set major league records for career hits and total bases as a shortstop that were later broken by Derek Jeter and Cal Ripken Jr. respectively. His 2,581 games as a shortstop were a major league record until 2008, and the AL record until 2014. He held the major league records for career assists (8,016) and double plays (1,553) until Ozzie Smith passed him in 1994 and 1995; he still holds the AL records for assists, putouts (4,548), and total chances (12,930), though Ripken broke his AL double play mark in 1996. Aparicio's career fielding percentage (.972) ranked second in AL history when he retired, one point behind Lou Boudreau. Legendary hitter Ted Williams called Aparicio "the best shortstop he had ever seen".
He was inducted into the National Baseball Hall of Fame in 1984, the first Venezuelan player to be so honored. He is currently the oldest living Hall of Fame player, following the death of Willie Mays in 2024.
Aparicio was born in Maracaibo, Zulia State, Venezuela. His father, Luis Aparicio Sr. (nicknamed Luis Aparicio "El Grande"), was a notable shortstop in Venezuela and owned a Winter League team with Aparicio's uncle, Ernesto Aparicio.
At the age of 19, Aparicio was selected as a member of the Venezuelan national team in the 1953 Amateur World Series held in Caracas; Venezuela took the silver medal in the tournament. He played mainly third base and left field, though took the field at shortstop in the climactic game against Cuba; his selection by manager José Antonio Casanova was criticized (especially because his father was on the team's coaching staff). Nevertheless, Aparicio finished the tournament with a .350 batting average with seven runs batted in, third best on the team.
He signed to play for the Gavilanes de Zulia, the local professional team in Maracaibo, alongside his father in 1953. In a symbolic gesture during the team's home opener on November 18, 1953, his father led off as the first hitter of the game, took the first pitch, and had Aparicio Jr. take his place at bat.
The Cleveland Indians had been negotiating to sign Aparicio, but Indians General Manager Hank Greenberg expressed the opinion that he was too small to play in the major leagues. Chicago White Sox general manager Frank Lane, on the recommendation of fellow Venezuelan shortstop Chico Carrasquel, then signed Aparicio for $5,000 down and $5,000 in first-year salary. After only two years in the minor leagues, he made his major league debut at the age of 22, replacing Carrasquel as the White Sox shortstop in 1956. Aparicio would lead the American League in stolen bases, assists and putouts, and won both the AL Rookie of the Year and The Sporting News Rookie of the Year awards. He was the first Latin American player to win the Rookie of the Year Award.
Aparicio quickly became an integral member of the Go-Go White Sox teams of the mid-1950s, who were known for their speed and strong defense. Over the next decade, Aparicio set the standard for the spray-hitting, slick-fielding, speedy shortstop. He combined with second baseman Nellie Fox to become one of the best double play combinations in the major leagues. Aparicio once again led the AL in stolen bases and assists in 1957 as the White Sox held first place until late June before finishing the season in second place behind the New York Yankees. On September 7 against the Kansas City Athletics, he hit two home runs for the only time in his career, leading off the game with an inside-the-park home run and adding a three-run shot in the 4th inning as the White Sox won 8-2.
In 1958, Aparicio earned recognition as one of the top shortstops in the major leagues when he was selected to be the AL's starting shortstop in the All-Star Game. The White Sox once again finished the season in second place behind the Yankees, after being in last place on June 14. Aparicio again led the league in stolen bases, assists and putouts, and won his first Gold Glove Award.
Aparicio was the team leader when the "Go-Go" White Sox won the AL pennant in 1959, finishing the regular season five games ahead of the Cleveland Indians. After stealing 56 bases to tie Wally Moses' 1943 team record, he was runner-up to Fox in the Most Valuable Player Award balloting. Aparicio was selected as a starting All-Star for the second time and also won a second Gold Glove Award. He posted a .308 batting average in the 1959 World Series as the White Sox were defeated by the Los Angeles Dodgers in a six-game series. The White Sox record stood until Rudy Law stole 77 bases in 1983. When Aparicio stole 50 bases in his first 61 attempts in 1959, the term "Aparicio double" was coined to represent a walk and a stolen base. Since the 2019 death of teammate Johnny Romano, Aparicio has been the last surviving player to play with the White Sox in the 1959 World Series.
In 1960 and 1961, Aparicio continued to be one of the top shortstops in the league, finishing at or near the top in fielding percentage and assists. His 1960 total of 551 assists was the highest in the major leagues since 1943, and the highest AL total since White Sox star Luke Appling recorded 556 in 1935; the last season above 550 previous to that had been in 1911. In 1962, Aparicio showed up overweight and had an off year, and the White Sox offered him a reduction in salary for the 1963 season. An enraged Aparicio said that he would quit rather than accept a decrease in pay and demanded to be traded. The White Sox eventually traded him to the Baltimore Orioles with Al Smith for Hoyt Wilhelm, Ron Hansen, Dave Nicholson and Pete Ward in January 1963.
Aparicio regained his form in Baltimore and continued to lead the league in stolen bases and in fielding percentage, producing a career-high .983 fielding percentage in 1963. Together with Brooks Robinson and Jerry Adair, he was part of one of the better defensive infields in baseball. In 1964, he led the league in stolen bases for a ninth consecutive year, with his 57 steals breaking George Sisler's franchise record of 51 set with the 1922 St. Louis Browns, and won his sixth Gold Glove Award. Aparicio posted a .276 batting average with 182 hits in 1966, tied with teammate Frank Robinson for the second-most hits in the league behind Tony Oliva and won a seventh Gold Glove Award as the Orioles clinched their first American League pennant. He finished ninth in the MVP balloting, in which teammates took the top three spots, and helped the Orioles sweep the Los Angeles Dodgers in the 1966 World Series.
