Mets target Ryan Mountcastle, consider trades for All-Star upgrades

The New York Mets are exploring options to fill the void left by first baseman Pete Alonso, who remains unsigned. A recent mock trade suggests acquiring Baltimore Orioles' Ryan Mountcastle as a potential replacement, offering two prospects in return. Alternatively, the Mets could utilize Jesse Winker, who expressed willingness to play first base, as well as internal options like Mark Vientos or Brett Baty. The Mets are also considering signing Jurickson Profar, who had a strong season, and trading either Starling Marte or Jeff McNeil to create roster space. The ongoing uncertainty around Alonso's future complicates the Mets' offseason strategy, as they aim to build a competitive roster for the upcoming season. In addition, the Mets are reportedly eyeing a trade for Seattle Mariners ace Luis Castillo, which could further bolster their pitching staff.
