After losing to Mandaue City, which eventually emerged as the top team in pool B, Toledo City had to battle it out with Catmon since both are tied with a 3-1 win-loss card in order to secure the semis berth.
Toledo City claimed the first set, 25-23, but the momentum shifted to Catmon's side in the second canto, 25-19.
Good thing, Catmon ran out of gas and gave up the fight to Toledo City in the deciding set, 25-17.
With the win, Toledo City joined Mandaue City in the semifinals.
Mandaue City, on the other hand, still has a game left versus Medellin, but the outcome of the game will no longer affect their bid in the penultimate round.
In pool A, it's the defending champion Lapu-Lapu City and Talisay City advancing to the next round.
Lapu-Lapu got the top spot after winning against Talisay in straight sets.
Lapu-Lapu came out clean after sweeping all qualifying round assignments, the last one of which saw them winning with 25-23, 25-22.
The cross-over semifinal round takes place Friday with the winners going for the overall crown.
