Maile started at catcher and went 0-for-2 with a walk and a stolen base in Saturday's 4-3 loss to the Red Sox.

Maile, who has eight steals over 414 career games in MLB, has showed off his "wheels" of late. He's stolen two bases over his last three starts. In between, he scored from second base on a sacrifice-suicide squeeze bunt Friday night. Maile started a second straight game behind the dish while Tyler Stephenson copes with an undisclosed injury. Stephenson eventually entered Saturday's game as a pinch hitter in the ninth inning, which suggests Maile's run as the primary backstop could end in the coming days.

Barnhart went 1-for-3 with an RBI in Saturday's 12-1 loss to the Phillies.

Barnhart drove in Arizona's lone run and has RBI in three of his last four starts. He stepped in as the starting catcher Saturday after the Diamondbacks placed primary backstop Gabriel Moreno (thumb) on the 10-day injured list. Barnhart moves to the top of the depth chart with Jose Herrera called up from Triple-A Reno to serve as the backup.

Davis (concussion) has resumed most baseball activities, MLB.com reports.

Davis has been on the 7-day injured list since June 14 and had continued to experience some mild symptoms as of Friday. As a result, the earliest he will be activated from the IL is Monday, though his absence could extend beyond that.

D'Arnaud went 1-for-3 with a two-run home run in Saturday's 8-3 loss to the Yankees.

While his playing time has been limited in June, d'Arnaud is starting to make the most of it. He has a homer in two of his last three games, giving him seven long balls on the year. The catcher is at a .242/.310/.464 slash line with 24 RBI, 21 runs scored, 13 doubles and no stolen bases over 171 plate appearances. While Sean Murphy has struggled at the plate this season, he's hitting .244 in June, which has been enough to keep d'Arnaud in the backup catcher role.

Alvarez went 2-for-3 with a solo home run in Saturday's 8-1 loss to the Cubs.

Alvarez's solo home run off Jameson Taillon in the fifth inning was the only run the Mets could muster Saturday. He later added a double in the seventh frame and walked in the ninth. Alvarez has homered on back-to-back days and has gone 10-for-19 with two long balls and six RBI over his past five contests. The young catcher is hitting .284 with three home runs and 16 RBI in 88 at-bats this season.

Stephenson (undisclosed) fouled out in his only plate appearance during Saturday's 4-3 loss to the Red Sox.

Stephenson has been dealing with an undisclosed injury, but he was called upon to pinch hit for Luke Maile on Saturday. While Stephenson wasn't well enough to start the contest, it's certainly encouraging that he was able to take an at-bat.

Campusano (thumb) was placed on the 10-day injured list Saturday but isn't expected to miss more than the minimum amount of time, Jeff Sanders of The San Diego Union-Tribune reports

Campusano was scratched ahead of Friday's 9-5 win over the Brewers and held out of Saturday's 6-4 win with left thumb soreness before the Padres placed him on the IL. Brett Sullivan was called up from Triple-A El Paso take Campusano's place on the active roster, but Kyle Higashioka should get most of the work behind the plate while Campusano is out.

Campusano (thumb) is out of the lineup for Saturday's game against Milwaukee.

Campusano was scratched from Friday's lineup with soreness in his left thumb and will remain on the bench to begin Saturday's game. Kyle Higashioka will be behind the plate and bat ninth.

Stephenson (undisclosed) isn't in the Reds' lineup Saturday against the Red Sox.

Manager David Bell said Friday that Stephenson is day-to-day with an undisclosed injury. It's still unclear what the 27-year-old backstop is dealing with, but it's enough to sideline him for a second consecutive game Saturday. While he recovers, Luke Maile will pick up another start behind the plate and bat eighth.

Stubbs isn't in the Phillies' lineup for Saturday's game versus Arizona.

The lefty-hitting Stubbs will take a seat Saturday as the lefty-throwing Tommy Henry starts on the bump for the Diamondbacks. Rafael Marchan will instead start at catcher while batting ninth.
