Liga Occidental de Béisbol Profesional

The Liga Occidental de Béisbol Profesional (Western Professional Baseball League) was a baseball circuit that operated between 1954 and 1963 in Maracaibo, the capital city in the Venezuela state of Zulia. The league played their games at the old olympic stadium of Maracaibo.

The LOBP started to operate as a four-team league on December 7, 1954, and was managed by local entrepreneurs under the guidance of George Trautman, an American baseball executive, who also helped the league to join organized baseball to become a professional baseball circuit.

Throughout the years, the league modified the number of games in the schedule and adopted playoffs. A significant innovation came before the 1953–1954 season, when the Venezuelan Professional Baseball League and the LOBP agreed to have the clubs with the best records from each circuit meet in a National Championship Series called El Rotatorio (the rotational), organized by the VPBL, which was the first and only in the league's history.

By then, both leagues were short of teams to play the regular season. Accordingly, the Cervecería Caracas and Navegantes del Magallanes teams represented the VPBL, while the Gavilanes and Pastora clubs represented the LOBP. Then, the Pastora team won the VPBL championship and advanced to the 1954 Caribbean Series.

Following an agreement between the two leagues, the interleague playoff games would be played immediately following the 1957–1958 season. As a result, the winning team would represent Venezuela in the 1958 Caribbean Series. The Rapiños de Occidente won the LOBP pennant, while the Industriales de Valencia did the same in the VPBL. After that, the Industriales swept the Rapiños, 4–0, in the best-of-seven series.
