Puerto Rico advanced the finals again in 2017, falling to the United States 8−0 in earning their second consecutive silver medal, and only loss of the tournament. Molina made a strong case to be named Most Valuable Player (MVP) of the entire tournament, batting .333 with two home runs and a .583 slugging percentage in six games. After collecting three hits and a home run in eight at bats over two games in Pool F competition, he was named that group's MVP. In the semifinal game against the Netherlands, he picked two runners off base in one inning. He was named the catcher of 2017 All-World Baseball Classic team, his second All-WBC honor. Also, the coaching staff often allowed him to conduct the preparation meetings, took his advice on construction of the starting rotation, and when to remove tiring pitchers.
