Bob Klapisch of the Bergen Record reports that the Mets are expected to option Lucas Duda to Triple-A in order to clear a roster spot for Matt Harvey. They won't need to make a move for a few days, as Harvey isn't starting until Thursday. It's a little surprising given that Duda has been a fixture in the lineup all season, but he has really struggled this month, batting just .140/.260/.233. Jordany Valdespin is getting his first career start in right field Monday.
