ヨエニス・セスペデス
In spring training in 2018, Smith was set to compete with Adrián González to be the Mets' starting first baseman, but he missed most of spring training due to a quadriceps injury. He began the season in Las Vegas, and was promoted on May 11 when Jay Bruce went on the paternity list and demoted when Bruce returned on May 14. Smith was promoted again on June 11 when the Mets released Adrián González. Smith was demoted again on July 20 after Yoenis Céspedes was activated from the disabled list.
