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.

Contreras went 3-for-4 with two homers and three RBI in Sunday's win versus the Mets.

The 27-year-old backstop notched his sixth career multi-homer performance with this effort. Contreras opened his team's scoring with a solo shot off New York starter Sean Manaea in the fourth, and then returned in the fifth to launch a two-run long ball off reliever Reed Garrett. The two-time All-Star is slashing .255/.354/.389 with 12 home runs, five steals, 65 runs scored and 52 RBI in 486 total plate appearances.

Pozo is out of the lineup for Sunday's game against the Cubs.

After catching all nine innings of Saturday's 9-1 loss, Pozo will take a seat for the series finale. Pedro Pages will get the nod behind the dish Sunday.

Alvarez is out of the lineup for Sunday's game against the Brewers.

After catching eight innings and going 1-for-3 with a walk Saturday, Alvarez will get a breather for the Sunday afternoon contest. Luis Torrens will work behind the plate.

Baldwin is out of the lineup for Sunday's game against the Marlins.

Baldwin will get a chance to catch his breath after he started the first four games of the series, including both ends of Saturday's doubleheader, while going 7-for-17 with two home runs, one walk, 10 RBI and four runs. Sean Murphy will handle catching duties and Marcell Ozuna will get the nod at designated hitter.
