Coming into the season, Flores was expected to serve as a backup utility infielder around the diamond throughout the year, primarily against left-handed pitching. Due to David Wright's chronic spinal condition, Flores has primarily filled in at third base. He has hit .180/.255/.280 with a 49 wRC+ in 55 plate appearances so far this season.
Flores is the most recent in a series of minor but potentially worrisome injuries for the Mets. In addition to the need to spell Wright, Walker had to sit for three games thanks a bruised right shin. Noah Syndergaard had his right elbow examined two weeks ago, but tests came back clean. Steven Matz will skip his next start because of elbow soreness.
The Mets are likely to call up Sean Gilmartin from Triple-A Las Vegas to take Flores's spot on the roster.
