1957 Caribbean Series

Balboa most prominent player was Winston Brown, who pitched a six-hit, one run complete game and a four-hit shutout, in both cases against Venezuela.

Another gem game from George Brunet (1–1, 17 SO, 1.76 ERA), who pitched the first shutout for a Panamanian team in Series history, and also hit one of the club's two homers.

The Mayagüez team was piloted by Mickey Owen, while RF Canena Márquez provided the support attack (375, three HR, five runs, .792 SLG).

The other major contributors were 1B Bob Speake (.391, one HR, five RBI, .652 SLG) and P José Santiago, who handed Marianao their only lost, throwing a three-hit shutout.

Emilio Cueche took a complete-game loss after giving up two unearned runs in Game 5, and later hurled two scoreless innings of relief for a perfect 0.00 ERA, the best for the Series.
