Liga Occidental de Béisbol Profesional

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.

In the next playoff series, the Indios de Oriente VPBL champion team defeated the Rapiños, 4–3, and advanced to the 1959 Caribbean Series. Then, the Rapiños returned in 1959–1960 and won the pennant. This time, the Venezuelan Professional Baseball League season was suspended due to a players' strike, and the Rapiños club was invited to participate in the 1960 Caribbean Series.

During its 10 years of existence, the Zulia league confronted many crises, big and small, in that short period. For a time in the late 1950s, a lack of competitive balance seemed to pose the greatest threat to the league.

The beginning of the end came when the 1961–1962 season was cancelled. After that, the league resumed operations in 1962–1963, but the average attendance was less than half what it was in previous years.

Due to economic pressure, the LOBP folded on December 3, 1963, just one month after starting the 1963–1964 season.

Pastora was the only club that participated in all seasons of the league, winning two pennants, while the most successful team was the Rapiños, who collected a total of five titles during its six seasons in the circuit.
