NEW YORK -- Mets right-hander Kodai Senga was diagnosed with a Grade 1 hamstring strain Friday and will be reevaluated in two weeks, manager Carlos Mendoza said after the team's 7-5 loss to the Tampa Bay Rays.
Senga, the Mets' top starter this season, suffered the injury running to cover first base in the sixth inning of Thursday's win against the Washington Nationals. He was placed on the injured list Friday morning, but the Mets didn't know the extent of the setback until he was examined in the afternoon.
