Luis Lobo (born 9 November 1970 in Buenos Aires, Argentina) is a professional male tennis player from Argentina, who won the gold medal in the men's doubles competition at the 1995 Pan American Games.

He reached his career high doubles ranking, World No. 12, on 21 July 1997. He is currently a coach, and has worked with players including Spain's Carlos Moyà and Argentina's Juan Mónaco.

The Gauchito Gil (literally "Little Gaucho Gil") is a legendary character of Argentina's popular culture. His full name was Antonio Mamerto Gil Núñez and he was allegedly born in the area of Pay Ubre, nowadays Mercedes, Corrientes, possibly in the 1840s, and died on 8 January 1878. He is regarded as the most prominent gaucho saint in Argentina.

Popular accounts vary, but in broad terms the legend tells that Antonio Gil was a farmworker and that a wealthy widow fell in love, or had an affair, with him. When her brothers and the head of the police (who was also in love with the widow) found out about their relationship, accused him of robbery and tried to kill him. He enlisted in the army to escape from them. In the army, he fought against the Paraguayan army. Finally, he could come back to his village as a hero.

But, when he arrived at his village, he was forced to return to the army to fight in the Argentine Civil War. It was a brother versus brother war and "Gauchito" Gil was tired of fighting. Therefore, he decided to desert. During this time he became an outlaw and acquired a reputation as a Robin Hood figure, for his efforts to protect and help the needy.

Luis Enrique "Tite" Arroyo, (born February 18, 1927), is a former major league baseball pitcher.

Luis Arroyo, from Peñuelas, Puerto Rico, made his Major League Baseball debut on April 20, 1955. A stocky left-hander, he spent one season primarily as a starter with the St. Louis Cardinals. Though he was a member of the National League All-Star team that year, he was traded to the Pittsburgh Pirates the next spring, where he was moved to the bullpen. Struggling to establish himself in the role, he went from the Pirates to first the Cincinnati Reds, then the New York Yankees. Arroyo was the first Puerto Rican to play for the Yankees, and despite his earlier struggles, he quickly became an important contributor to the club.

American League hitters had little success against Arroyo's screwball, and after a solid contribution at the back of their bullpen in 1960, he enjoyed the best season of his career in 1961. That year, Arroyo pitched 119 innings with a 2.19 ERA, while winning 15 games as the team's relief ace. His totals of 65 games pitched and 29 saves both led the league, he surrendered only five home runs in a season where league-wide offensive totals were very high by historical standards, and was named to his second All-Star team while finishing sixth in AL MVP voting.
