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

He'll take a seat for the series finale after picking up starts behind the plate Monday and Tuesday. Elias Diaz will handle catching duties Wednesday in Higashioka's stead.

D'Arnaud is out of the lineup for Wednesday's game against the Reds.

D'Arnaud has alternated starts behind the plate with Sean Murphy since the former returned from the paternity list last Thursday. Murphy will get the nod Wednesday after d'Arnaud went 1-for-4 with a walk in Tuesday's 6-5 loss.

Bailey is out of the lineup for Wednesday's game against the Orioles, Shayna Rubin of the San Francisco Chronicle reports.

Bailey will get some rest after he caught all nine innings of Tuesday's 10-0 win. Curt Casali checks in behind the dish for Bailey on Wednesday.

Ruiz is not in the lineup for Wednesday's contest versus the Mets, Andrew Golden of The Washington Post reports.

Ruiz will get a routine day off after starting in each of the last four games. Drew Millas will handle catching duties for Washington in the series finale.

The Diamondbacks outrighted Knizner to Triple-A Reno on Tuesday.

Knizner cleared waivers after being removed from the 40-man roster over the weekend, but he will remain in the organization for the time being. The veteran catcher is a career .210/.279/.317 hitter over parts of six major-league seasons.

Moreno isn't in Arizona's lineup for Tuesday's game against the Rockies.

Moreno went 2-for-3 during his first start back from the injured list Monday, and he'll take a seat Tuesday as the D-backs ease him back into regular playing time. While he rests, Jose Herrera will catch for Jordan Montgomery and bat ninth.

Smith is not in the lineup for Tuesday's contest in Miami.

It's a routine day off for Smith, who had started four of the last five contests behind the plate. Hunter Feduccia is doing the catching in what will be his second career start.

Moreno started at catcher and went 2-for-3 in Monday's 3-2 loss to the Rockies.

Moreno, who was activated off the 10-day injured list Sunday, made his first start since rejoining the team -- he was used as a pinch hitter Sunday but did not play defensively. He missed nearly all of August and the first half of September with an adductor strain. The Diamondbacks optioned rookie backstop Adrian Del Castillo to Triple-A Reno on Monday, signaling that Moreno is ready to take on near-everyday duty.

Amaya went 3-for-4 with a triple, a run scored and two RBI in Monday's 9-2 win over the Athletics.

Amaya batted ninth and did his part to contribute to Chicago's 18-hit barrage. The catcher recorded just his second triple of the season and snapped an 0-for-7 slump that extended over his last five appearances. Amaya has struggled to find a ton of offensive consistency this year, though his playing time alone gives him a decent amount of fantasy value at a thin position.

Contreras went 1-for-2 with a two-run double, two walks and a stolen base in Monday's 6-2 win over the Phillies.

Contreras opened the scoring with a two-run double in the third inning and was part of a double steal in the seventh. Over his past 10 games, the catcher has three multi-hit efforts with five extra-base hits and 10 RBI. On the season, he is hitting .281 with 22 homers, 90 RBI, 94 runs scored and seven steals across 640 plate appearances.
