"Kodai Senga is injured," MLB .com's Anthony DiComo reported. "He took a fall at first base attempting to beat a runner to the bag, and he spent a long time down on the ground surrounded by coaches and trainers."

If Senga lands on the injured list for an extended period of time, the Mets will likely slide Paul Blackburn back into the rotation and call up reliever. When asked about using Blackburn, Mendoza said the right-hander will be available out of the bullpen for their next series against the Rays, and that they “will go from there.”

New York Mets right-hander Kodai Senga exited Thursday's win against the Washington Nationals ( box score) in the sixth inning after straining his hamstring. After the game, manager Carlos Mendoza announced Senga will head to the injured list and will undergo an MRI on Friday to determine the severity of the injury.
