Kodai Senga, who has not pitched for the New York Mets this season, is scheduled to throw a bullpen session on Wednesday that could determine how soon he returns to game action.

Senga said that he is overhauling his mechanics as part of his rehab process: "With my current mechanics, I didn't think I'd be able to come back at 100%."

The 31-year-old was shut down in February because of a shoulder strain.

He received a PRP injection and was initially shut down for three weeks. Senga's mechanical reinvention has prolonged his absence.
