Mets RHP Noah Syndergaard will be placed on the 10-day disabled list after an MRI revealed a partially torn right lat muscle, the team announced..
Syndergaard, who refused an MRI last week despite having his start pushed back from Thursday to Sunday due to discomfort in his biceps and shoulder, left Sunday's start in the second inning.
There is no timetable for his return, according to the team, and GM Sandy Alderson will discuss Syndergaard's status at 4 p.m. Monday.
The 24-year-old Syndergaard gave up five runs and five hits in just 1 1/3 innings on Sunday and saw his ERA jump from 1.
