For the first time, Vargas got to play winter ball in his home country. Imanol suited up for Gigantes del Cibao in San Francisco de Macoris for four games as a part of the Dominican Winter League.

As a free agent, Vargas signed with the Los Angeles Angels for 2024. In May, he was assigned back to low-A, this time at Inland Empire.
