Mets place Tomás Nido on injured list, call up Patrick Mazeika and Trevor Williams

Heading into the first game of their three-game series in San Francisco, the Mets have placed catcher Tomás Nido on the injured list with a sprained left thumb, optioned relief pitcher Geoff Hartlieb to Triple-A Syracuse, and called up catcher Patrick Mazeika and pitcher Trevor Williams to take those two spots on the active roster.

The Nido injury comes as a surprise. The Mets’ backup catcher this year, Nido has hit .231/.275/.343 with three home runs and a 70 wRC+ in 142 plate appearances this year. Mazeika, who is best known for his walk-offs early in the season, has spent the vast majority of his season in Syracuse, but in 24 major league plate appearances, he has a .273/.333/.409 line with a 108 wRC+.

Hartlieb has made just three appearances for the Mets this year and has a 14.54 ERA in them. Williams, who was part of the trade that brought Javier Báez to the Mets at the deadline, has a 5.06 ERA on the season but pitched reasonably well in his first appearance for the Mets, throwing four-and-a-third innings while allowing one run in a spot start.
