Julio Cesar Baldivieso's Wilstermann came from behind away at Nacional Potosi to post a 2-1 win, and extend their unbeaten streak to five matches.
Nacional led on 14 minutes, when Walter Rioja fired the home side ahead - and they preserved their lead until the break.
But Wilstermann turned the game on its head shortly after the interval, Carlos Neumann and Enrique Diaz's goals firing them ahead by the 53rd minute.
Miguel Angel Zahzu's San Jose had a 2-0 win at home to Sport Boys, Delio Ojeda and Mauro Bustamante scoring first-half goals.
The result was The Strongest's third loss in succession, which leaves them in eighth spot with 14 points - six behind the leaders.
Blooming shot out to a two-goal lead early - Sergio Almiron's penalty was followed up by Joselito Vaca's strike in the 24th minute.
Blooming's Pablo Salinas made it 3-3 in the 74th minute but Rudy Cardozo had the final say seven minutes later with the winner.
