The Mets reinstated Guillorme (groin) from the 10-day injured list Monday.
Guillorme had been on the IL with a strained groin since Aug. 15. Having hit .283/.355/.357 and provided solid defense around the infield this season, the 27-year-old should get plenty of playing time for the remainder of the season, especially while Starling Marte (finger) is out of the lineup.
