Perez isn't starting Wednesday against the Cubs.

Perez started in the last three games and went 1-for-7 with two walks and a strikeout. Tyler Heineman will start behind the dish and bat eighth.

Nido isn't starting Wednesday against the Cardinals.

Nido went 0-for-3 with two strikeouts in Tuesday's nightcap, and he'll be on the bench for the third time in the last five games. Patrick Mazeika will start behind the plate and bat ninth.

Nola isn't starting Wednesday against the Phillies, Kevin Acee of The San Diego Union-Tribune reports.

Nola started in the last two games and went 1-for-6 with two RBI. Jorge Alfaro will start behind the dish and bat eighth Wednesday.

The Pirates announced Wednesday that Perez will undergo season-ending surgery on his left hamstring in the near future, Alex Stumpf of DKPittsburghSports.com reports.

Perez, who signed a one-year, $5 million deal with Pittsburgh in November, appeared in just 21 games before hitting the shelf earlier this month with what ultimately proved to be a season-ending injury. The Pirates will likely lean on a platoon of Michael Perez and Tyler Heineman at catcher the rest of the way, barring any further additions to the position group.

Rortvedt (knee) underwent arthroscopic surgery on his left knee Wednesday.

Rortvedt missed the start of the regular season due to an oblique injury, and his rehab assignment was recently paused due to a knee injury that ultimately required surgery. The procedure was classified as a meniscus clean-up, and the backstop is expected to have a recovery timetable of 6-to-8 weeks prior to returning to game action. As a result, the 24-year-old will likely be sidelined until at least late June or sometime in July.

Alvarez is hitting .248/.339/.438 with four homers and a 14:31 BB:K across 28 games for Double-A Binghamton.

He hit all four of those homers in his first six games of the season and has managed none since, with an ugly .210/.313/.272 line across his last 22 contests. That said, Alvarez has been showing signs of emerging from the slump recently, as he actually has a six-game hitting streak going during which he's hit .409 with a couple doubles. If he can keep that up, we might see him come up at some point this season, especially if James McCann's wrist injury lingers or further injuries hit the Mets' catcher corps; however, Alvarez is just 20 years old and would be best served by additional minor-league development time.

Serven is starting at catcher and batting ninth in Wednesday's series finale against the Giants.

After being called up Tuesday, Serven is set to make his MLB debut Wednesday. Through 77 at-bats with Triple-A Albuquerque this season, the catcher produced a .273 average with five homers and 11 RBI.

Murphy is not starting Wednesday's series finale versus the Twins, Matt Kawahara of the San Francisco Chronicle reports.

The catcher will rest after starting six consecutive games, producing just one hit over that stretch while driving in three runs. Christian Bethancourt will draw the start behind the plate and bat fifth Wednesday.

Diaz is out of the lineup for Wednesday's game against the Giants.

Diaz will get a routine breather after he started behind the plate in each of the Rockies' last three games. With Diaz on the bench, Brian Serven -- who was called up from Triple-A Albuquerque on Tuesday -- will make his MLB debut as the Rockies' starting catcher in the series finale.

Narvaez isn't starting in Wednesday's series finale versus the Braves.

With the Brewers facing left-hander Max Fried, Narvaez will stay on the bench for the second straight contest. Victor Caratini will start at catcher and bat ninth in the game.
