Mets placed INF Marcus Semien on the 10-day injured list with a left hip flexor strain.
Semien’s injury comes a bit out of nowhere, and the 35-year-old veteran will now be out of action for at least a week-plus; likely longer as flexor strains don’t often suggest a minimum stint on the injured list. There should be further updates on Semien in the coming days,, but for now, Ronny Mauricio is up from Triple-A to take his place on the roster and potentially in the lineup.
