A place in the Liguilla is on the line: San Marcos de Arica, strong at home, against a Puerto Montt side with 9 goals in 13 away league games.

San Marcos should edge a tight, low-scoring game, but the quoted prices — 1.75 for a home win and 1.2 for San Marcos to avoid defeat — ask for more than the evidence supports, so nothing reviewed here is worth backing.

Context

With three rounds of the Liga de Ascenso left, San Marcos de Arica sit in the final Liguilla place and Puerto Montt are chasing the same post-season group after a 0-1 home loss to San Luis on 12 October. The hosts also arrive from a 3-0 defeat at Deportes Antofagasta, so this fixture is a direct swing opportunity for two clubs fighting over the last playoff spots. Puerto Montt's own club preview frames it as a must-win to keep the post-season 'dream' alive. Neither side's fate is settled here, and the table can still move across the closing rounds.

The ANFP Tribunal de Disciplina rejected the governing body's first complaint, which sought San Marcos de Arica's expulsion for alleged falsified documentation, and instead fined the club 500 UF for late financial reporting on 2 October. A second accusation was expected during October, and on 15 October reports said the ANFP had dropped the first complaint while other clubs appealed. The unresolved case keeps a possible sporting sanction hanging over the club through the closing rounds. Any outcome is still speculative, since no points penalty or expulsion has been confirmed.

Puerto Montt's Copa Chile quarter-final against Colo Colo was halted at half-time by heavy rain in Santiago on 7 October, and the remaining 45 minutes were fixed for Tuesday 20 October at 18:00 at the Estadio Monumental. That gives the Velero an away league trip to Arica on Sunday followed by a decisive cup game two days later, a schedule that could shape how they set up and rotate here. The club confirmed the cup rescheduling, while Colo Colo hold the tie lead. Whether it actually changes this XI is unclear, since no lineup has been published.
