Pompeyo Antonio "Yo-Yo" Davalillo Romero is a former Major League Baseball player. Listed at 5' 3", 140 lb., Davalillo batted and threw right-handed. He is listed in major league records as having been born on June 30, 1931, in Cabimas, Venezuela (Venezuelan baseball official resources indicate July 5, 1928). His younger brother Vic also played in the majors.
A slick shortstop with a quick bat and feet, Davalillo was drafted by the New York Yankees in 1953 and later transferred to the Washington Senators. He appeared with the Senators late in the season and hit .293 in 19 games. He had a promising future, but his aversion to airplane travel, combined with a severe injury, curtailed his career in the major leagues.
Davalillo played eleven seasons in minor league baseball, nine of them at Triple-A level, and posted a .270 average in 1207 games.
Davalillio also played in Mexico (1962–64) and spent fourteen seasons with the Leones del Caracas of the Venezuelan Winter League (1952–53 and 1965–66). He was a .276 hitter with three home runs and 130 RBI in 469 VWL games, including 246 runs, 58 doubles, 19 triples and 67 stolen bases. He later coached and managed in the league.
