Last year, one of the weakest positions for the Pittsburgh Pirates was catcher. They entered the year with Francisco Cervelli and Elias Diaz behind the plate, which was a productive tandem in 2018.
Throughout the 2018 season, the duo combined for a 4.8 bWAR in 681 plate appearances. But Cervelli played only 34 games with the Pittsburgh Pirates in 2019 before being released to sign with the Atlanta Braves, and Diaz was flat out awful.
Diaz got the lion’s share of playing time behind the plate, appearing in 101 games and receiving 332 plate appearances.
