San Juan hosted the Caribbean Series for the second time in 1954, and Puerto Rico again took home the championship, this time through the Criollos de Caguas rather than the Cangrejeros de Santurce. Back-to-back Puerto Rican titles suggested that the island was entering a period of genuine regional strength, built on a winter circuit that was drawing quality players and developing homegrown talent at an accelerating pace. Winning on home soil added a particular satisfaction to the Criollos' title. This edition carries some unverified details and no Most Valuable Player was officially recorded. The Criollos' championship nonetheless confirmed that Puerto Rico could sustain excellence across consecutive years and across different clubs, not merely ride the strength of a single dominant roster. The 1954 result also interrupted what might otherwise have been a longer run of Cuban dominance in the tournament's early years, keeping the regional competition genuinely open heading into the second half of the founding decade.
