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

Though he'll take a seat in the series finale, Diaz may have at least temporarily overtaken Martin Maldonado as the Padres' top catcher. Diaz started in each of the Friars' last three games, going 3-for-12 with a double, five RBI and two runs.

Adams is out of the lineup for Wednesday's game against the Astros.

Adams will receive a routine day off for the afternoon contest after he started in each of the Nationals' previous three games. Drew Millas will replace Adams behind the dish and will bat eighth.

Baldwin is out of the lineup for Wednesday's game against the Royals.

The left-handed-hitting Baldwin will take a seat for the second time in the series while the Royals send another lefty starter (Angel Zerpa) to the bump. Since Zerpa is serving as an opener and may not cover more than an inning or two, Baldwin could be a candidate to replace Sean Murphy at catcher or Marcell Ozuna at designated hitter once Zerpa exits the contest.

Marchan will start at catcher and bat ninth in Wednesday's game against the White Sox.

He'll draw his 20th start of the season while top backstop J.T. Realmuto gets a breather for the day game after a night game. Marchan will head into Wednesday's contest with a .175/.268/.254 slash line to go with one home run, six RBI and five runs over 72 plate appearances on the campaign.

Kirk (concussion) is tentatively on track to play a rehab game with Triple-A Buffalo on Saturday before being activated from the 7-day injured list Sunday, Keegan Matheson of MLB.com reports.

Kirk was diagnosed with a concussion after taking a foul tip off the mask in a game this past weekend. However, he has recovered well since then, and as long as he keeps progressing well, he'll be in line for a minimum-length absence. Tyler Heineman has been handling the primary catching duties for the Blue Jays since Kirk went down.

Narvaez is out of the lineup for Wednesday's game against the Twins.

He will rest for just the third time in 12 games since the All-Star break while Connor Wong receives a start behind the dish. Narvaez has gotten off to a slow start to the second half, going just 5-for-35 (.143 average) with one home run, two RBI and three runs.

Dingler is out of the lineup for Wednesday's game against the Diamondbacks.

Dingler will receive a rest after he was behind the plate for each of Detroit's last three games while going 7-for-13 with one home run, four runs and five RBI. Jake Rogers will form a battery with starting pitcher Chris Paddack on Wednesday in the latter's Detroit debut.

Realmuto is absent from the lineup for Wednesday's contest against the White Sox.

Realmuto will get a breather in Wednesday's matinee after starting each of the previous eight contests. Rafael Marchan will fill in behind the plate and will bat ninth for the Phillies.

Heineman is out of the lineup for Wednesday's game against the Orioles.

Heineman will get a breather for Wednesday's matinee after he went 3-for-3 while starting behind the plate in the Blue Jays' 3-2 loss Tuesday night in the second game of a doubleheader. Ali Sanchez will get the nod at catcher Wednesday, but Heineman is expected to see the bulk of the starts while top backstop Alejandro Kirk (concussion) is on the shelf.

The Orioles signed Reetz to a minor-league contract Tuesday.

Reetz had been with Triple-A Syracuse in the Mets organization, where he slashed .197/.287/.470 with 11 home runs in 43 games before being released earlier this month. The 29-year-old will give the Orioles some experienced catching depth at Triple-A Norfolk.
