3 Mets who will be called up by the All-Star break and who they will replace

2) Second New York Mets player who will be called up by the All-Star break - Mark Vientos.

For as long as he has been the property of the Mets, Mark Vientos has been called a man without a position. There are places he can play, but they are not places of need for the team. His best position is first base, where Pete Alonso calls home. His other position is third base where the Mets already have a log jam. Vientos’ lack of defense makes it difficult to see him moving to some other position.
However, the National League has adopted the DH, a position that appears custom made for Mark Vientos.

The New York Mets player that he will replace – Tim Locastro.

The Mets don’t have a right handed DH on their depth chart at this point. While filling that position by committee might be a short term solution, Vientos fills a need here. Much like Brett Baty, the real surprise was that the Mets didn’t choose to bring Vientos with them. Tim Locastro will be the odd man out in this transaction, as carrying a good fielding fifth outfielder who only hit .186 last season is a luxury this team can’t afford. Vientos was selected in the second round of the 2017 Major League draft. He hit 22 home runs at AA Binghamton two years ago and 24 more at AAA Syracuse last year. He’s about as ready as he’s going to get.
