Millas is out of the lineup for Wednesday's game against the Athletics.

Riley Adams will get the nod behind the plate Wednesday, but Millas may have made a case for turning the Nationals' catcher spot into more of a timeshare until Keibert Ruiz (concussion) returns from the injured list. Millas started behind the plate in both of the previous two games and went a collective 4-for-8 with two doubles, two RBI and two runs. He now owns a .367 average and .467 slugging percentage over 33 plate appearances in the majors this season.

Narvaez is absent from the lineup for Wednesday's contest against the Royals.

Narvaez started Tuesday's game, but this will be the third time over the last four contests that he's been absent from the lineup. He's been in a rut at the dish, going 1-for-23 over his last six contests. Connor Wong will fill in at catcher Wednesday.

Pozo is out of the lineup for Wednesday's game against the Dodgers.

Pozo will take a seat for the day game after he went 1-for-3 with a walk and a run scored while catching all eight innings of the Cardinals' 12-6 loss Tuesday night. Pedro Pages will handle catching duties Wednesday, and he and Pozo have now alternated starts behind the plate over the last six contests.

Fortes will start at catcher and bat ninth in Wednesday's game against the Angels, Marc Topkin of the Tampa Bay Times reports.

Though he'll crack the starting nine for the series finale, Fortes looks poised to work in a timeshare behind the dish with Hunter Feduccia, after the latter was acquired from the Dodgers on Thursday. Feduccia had started in three of the previous four contests and may hold a slight edge over Fortes in terms of playing time at the moment.

Feduccia is absent from the lineup for Wednesday's contest against the Angels.

Feduccia and Nick Fortes have split the Rays' catching duties evenly since the former was added to the roster this past Friday. Fortes will be behind the dish and bat ninth in Wednesday's series finale.

Goodman is out of the lineup for Wednesday's game against the Blue Jays, Thomas Harding of MLB.com reports.

He'll be getting a routine breather for the matinee contest after going 2-for-3 with a home run, a walk, two RBI and two runs while catching all nine innings of the Rockies' 10-4 loss Tuesday night. Braxton Fulford will get the nod at catcher in the series finale.

Heineman (head) will start at catcher and bat eighth in Wednesday's game against the Rockies.

Heineman exited his most recent start Saturday due to a head contusion, but he avoided a concussion and made enough improvement to play the final two innings of Monday's 15-1 win. He'll make his return to the starting lineup Wednesday, but Heineman is expected to see few opportunities moving forward after top backstop Alejandro Kirk was reinstated from the 7-day injured list Sunday.

Cubs manager Craig Counsell said Wednesday that he expects Amaya (oblique) to return from the 60-day injured list ahead of the team's series in Toronto early next week, Mike McGraw of the Chicago Daily Herald reports.

Amaya has been shelved since May 25 due to a left oblique strain but is nearing the finish line in his recovery after he was cleared to begin a rehab assignment July 22. After spending the first three games of his assignment in the rookie-level Arizona Complex League, Amaya has moved up to Triple-A Iowa for his last six contests and has gone 5-for-16 with a 2:4 BB:K and no extra-base hits during that stretch. Once he's reinstated from the IL, Amaya will likely displace Reese McGuire as the top backup to No. 1 catcher Carson Kelly.

Kirk is absent from the lineup for Wednesday's game in Colorado.

Kirk started at catcher in each of the last three games after returning from the 7-day injured list, so he'll get some rest during Wednesday's matinee. Tyler Heineman will be behind the dish and bat eighth as Toronto goes for the sweep.

Baldwin went 2-for-4 with a walk and a run scored in Tuesday's loss to the Brewers.

Starting at DH and batting third, Baldwin continued to rack up hits. Over 16 games since the All-Star break, the rookie catcher is slashing .293/.359/.397 with six doubles and nine RBI, but his last home run came back on July 9.
