The Mets went into spring training last season with veteran Adrian Gonzalez and former first-round draft pick Dominic Smith fighting for the starting first baseman role, and there was every reason to be optimistic about the latter’s potential to win the job. He hadn’t impressed too much in his limited major league action in 2017, but he was still a young player with a lot of upside, and he impressed many by coming into camp in noticeably improved physical shape. There was a clear opening for Smith to establish himself as a player who would hold down the first baseman job for the Mets not just in 2018, but for years to come.
