Mets' Brandon Nimmo: Aggravates hamstring while running

Nimmo (hamstring) aggravated his strained hamstring while running Friday and will not return to Grapefruit League action as expected Saturday, Anthony DiComo of MLB.com reports.

The hope was that Nimmo would be able to get back on the field Saturday, but the recent setback will push back his timetable by a few days. Any further delays in his return to action could put his availability for Opening Day in jeopardy.
