Guillorme was placed on the 10-day injured list Sunday with a strained left hamstring, Anthony DiComo of MLB.com reports.
Guillorme apparently suffered the injury Saturday when he appeared as a pinch runner and came around to score. The 26-year-old's playing time was already set to diminish following the acquisition of Javier Baez, and he'll now be sidelined for at least the next 10 days.
