Ruiz remains in concussion protocol but is continuing to take part in baseball activities, Andrew Golden of The Washington Post reports.

While the fact that Ruiz hasn't been shut down from activity is encouraging, the Nationals haven't provided much information regarding the extent of his workouts, nor has the team provided any indication of how close he might be to exiting concussion protocol. Since Ruiz landed on the injured list July 8, the Nationals have turned to Riley Adams as their primary option at catcher.

Fermin went 1-for-4 with a two-run home run in Monday's 4-1 win against San Francisco.

Fermin's hit in the contest was a two-run shot to left field in the seventh inning that gave San Diego a 4-1 lead. The long ball was his first since joining the Padres via trade July 31. Fermin has brought his new team some much-needed consistent hitting from the catcher position -- since the trade, he's batting .370 (10-for-27) with four RBI over eight contests.

McCann is out of the lineup for Monday's game against the Rangers.

After starting behind the plate in three of Arizona's previous four contests, McCann will get a breather as the Diamondbacks kick off a three-game set in Texas. Adrian Del Castilo will handle the catching duties for the Diamondbacks on Monday.

Davis is out of the lineup for Monday's game against the Brewers.

Davis will take a seat for the series opener in Milwaukee after he started behind the plate in three of the Pirates' four games versus the Reds this past weekend. Joey Bart will get the nod at catcher and will bat seventh Monday.

Pozo is not in the lineup for Monday's game versus the Rockies.

Pozo looked like he might be inching ahead of Pedro Pages in the Cardinals' catcher pecking order earlier this month, but it will be Pages behind the dish Monday for the fourth time across the last five contests.

Pages will start at catcher and bat eighth in Monday's game against the Rockies.

With four starts behind the plate in the last five games, Pages appears to have at least temporarily wrested the primary catching gig away from Yohel Pozo. Already regarded as the superior defensive catcher of the two, Pages has helped his case for earning more playing time by running hot at the dish to begin August. Through five games this month, Pages has gone 6-for-16 with two home runs, one double, two walks, six RBI and three runs.

The Rockies designated Nola for assignment Monday.

The Rockies have been carrying three catchers for most of this month, but they will now go back to two backstops as Nola gets booted off the 26-man active roster and 40-man roster. Nola had played sparingly lately and will have the ability to elect free agency if he passes through waivers.

Pages went 1-for-3 with a two-run home run in Sunday's 3-2 win over the Cubs.

Pages opened the scoring with a third-inning blast off Shota Imanaga. While playing time hasn't been all that steady lately, Pages has made the most of it, going 7-for-19 (.368) with two homers and six RBI over his last six games dating back to July 29. The catcher is splitting duties with Yohel Pozo behind the dish in what's emerging as a fairly even timeshare. On the year, Pages has a .211/.256/.341 slash line with eight homers, 35 RBI, 29 runs scored and no stolen bases across 87 contests.

Diamondbacks manager Torey Lovullo said Sunday that Moreno (finger) will begin a rehab assignment Tuesday with Triple-A Reno, Alex Weiner of ArizonaSports.com reports.

Moreno is eligible to return from the 60-day injured list Aug. 18, and he looks like he'll have a shot to be activated on that date if all goes smoothly on his rehab assignment. The catcher was hitting .270 but provided just five home runs, one stolen base, 29 runs and 20 RBI through 53 games before he landed on the IL on June 19 due to a hairline fracture of his right index finger.

Fulford went 3-for-4 with one run scored in Sunday's 13-6 loss to the Diamondbacks.

During his current stint in the big leagues, Fulford has gone 4-for-14 with three strikeouts and one walk. He has been in the lineup for four of seven games since he was called up last Sunday, making two starts each at catcher and designated hitter. He's also started twice against right-handed pitchers, so it doesn't appear he'll be strictly platooned. Over 57 plate appearances in the majors, the 26-year-old has posted a .259/.281/.389 slash line with one home run, 11 RBI, five runs scored, one stolen base, two doubles and one triple.
