Stephenson (personal) was scratched from Thursday's lineup against the Cardinals, Mark Sheldon of MLB.com reports.

Stephenson was scratched moments before first pitch to be present for the birth of his child. He'll likely be placed on the paternity list and will miss between one and three additional games. Luke Maile took over behind the dish.

Barnhart is out of the lineup for Thursday's game against the Twins.

Barnhart had started behind the plate in three of the past four games but will get a breather for the day game after the night game. Jose Herrera will handle the catching duties Thursday, but Barnhart looks poised to serve as the Diamondbacks' top backstop until Gabriel Moreno (thumb) is back from the injured list.

Amaya is not in the lineup for Thursday's game in San Francisco.

Amaya started four of the first six games after Tomas Nido was added to the roster, but he'll yield to Nido for this one. The Cubs will be trying to avoid a four-game sweep at the hands of the Giants.

Bailey is out of the lineup for Thursday's game against the Cubs, Susan Slusser of the San Francisco Chronicle reports.

Bailey will get a breather for Thursday's day game after he started behind the plate in both of the first two games of the series. Curt Casali will spell him at catcher, forming a battery with starting pitcher Jordan Hicks.

Manager Bud Black said Tuesday that Diaz (calf) will be out for at least another week, MLB.com reports.

Diaz has resumed baseball activities but is not sprinting at full speed and is still experiencing some soreness. The Rockies have stressed the importance of Diaz returning at full strength, so his absence could extend into the middle of July. Jacob Stallings should remain the team's primary catcher in the meantime.

Diamondbacks manager Torey Lovullo said Wednesday the club is looking for Moreno (thumb) to return after a minimum stay on the 10-day injured list, Alex Weiner of Arizona Sports reports. He's eligible to return next Tuesday.

Moreno, who has been hitting off a tee and playing catch, will begin ramping up Thursday. That's when he'll catch a bullpen session thrown by injured ace Zac Gallen (hamstring). After that, the catcher is scheduled for a game in the Arizona Complex League over the weekend, setting up a potential return Tuesday, when the club kicks off a three-game set on the road against the Dodgers.

Alvarez went 3-for-3 with a home run, a double, a walk, three total runs and three total RBI in a 12-2 victory versus the Yankees on Wednesday.

Alvarez touched up Yankees starter Luis Gil for a two-run homer in the third inning and added a run-scoring double in the fifth. The catcher also singled for his third three-hit performance during his current nine-game hitting streak. Alvarez has been scorching during that stretch, batting .516 (16-for-31) with three home runs, nine RBI and a 7:7 BB:K. His slash line is up to an impressive .313/.383/.521 on the campaign.

Higashioka went 3-for-4 with two home runs and six RBI in Wednesday's 8-5 win against the Nationals.

Higashioka drove in all but two of San Diego's eight runs. He swatted a two-run homer to kick off the scoring in the second inning and capped his offensive outburst with a grand slam in the eighth. The grand slam was the first of Higashioka's career, while the multi-homer effort was his fifth as a big leaguer. He's hitting only .207 on the season but has otherwise provided good production with eight homers and 20 RBI in 32 games.

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

He'll be making his 22nd start of the season while top backstop Will Smith rests in the series finale. Over 74 plate appearances on the campaign, Barnes is hitting .203 with no home runs and two RBI.

Smith is absent from the lineup for Wednesday's contest versus the White Sox.

Smith started each of the previous three games at catcher but will begin Wednesday's contest on the bench. Austin Barnes will step in behind the plate Wednesday.
