What happened: The Mets designated infielder Zack Short for assignment and reinstated Marcus Semien from the injured list, per Bob Nightengale. The move opens a 40-man roster spot as New York brings Semien back into the infield mix. New York beat Philadelphia 4-1, though the Phillies still lead the series 2-1.

Why it matters: Semien's activation gives the Mets an established option back in the infield as the Aug. 3 trade deadline approaches. Short's designation shows New York prioritizing the returning regular over a depth piece on a 36-52 club looking to sort its roster before the deadline.

What to watch: The Mets and Phillies continue their series with Philadelphia still holding a 2-1 edge, and Short now faces a waiver claim or outright assignment within the DFA window.
