Mets prospect Francisco Alvarez may fill in for injured Narvaez.

Mets catching prospect Francisco Alvarez may be called up to the majors if Omar Narvaez goes on the injured list due to calf tightness. Alvarez is one of the top prospects in the sport and hit 27 home runs in the minors last year. Marlins outfielder Jazz Chisholm Jr. left the game with an apparent injury but was later listed as day-to-day with a stinger. The Giants recently signed Gary Sanchez to a minor league deal to bolster their catching depth, and president of baseball operations Farhan Zaidi is excited to see how he performs. Sanchez has a May 1 opt-out on his contract.
