After an offseason in which the Mets added several veteran middle infielders on minor league contracts to their Triple-A roster, it was unclear if there would be any room for Luis Guillorme at the big league level in 2019. Guillorme entered spring training coming off of a 2018 season in which he performed well with Triple-A Las Vegas - posting a 114 wRC+ with a batting line of .304/.380/.417 in 281 plate appearances in the Pacific Coast League - and earned a promotion to the big leagues to make his big league debut in the middle of May.
