Adams is absent from the lineup for the first game of Tuesday's doubleheader versus Atlanta.

It will be Jorge Alfaro doing the catching for the Nationals in the first game. Adams should be back behind the dish in the nightcap.

Atlanta transferred Murphy (hip) from the 10-day injured list to the 60-day IL on Tuesday.

The transaction frees up a 40-man roster spot for left-hander Jose Suarez, who was called up from Triple-A Gwinnett to start the first game of Tuesday's doubleheader with the Nationals. Murphy is done for the season following surgery last week to repair a right hip labral tear.

McCann went 1-for-4 with a two-run home run in Monday's 8-1 win over the Giants.

This was McCann's second straight game with a homer, and he's gone 6-for-15 over four contests in September. While his playing time has remained limited as backup to Gabriel Moreno, McCann continues to be productive in his rare chances to enter the lineup. McCann is at a .257/.327/.446 slash line with five homers, 15 RBI, 16 runs scored and four doubles across 36 games this season.

Stephenson went 2-for-4 with a three-RBI double and a run scored in Monday's 11-6 victory over the Cardinals.

Stephenson broke the game open Monday with a bases-clearing double in the ninth inning. That pushed his season total to 17 doubles as he works toward reaching 20 or more for the fourth time in his big-league career.

Baldwin went 3-for-5 with a home run and four RBI in Monday's 11-3 victory over the Nationals.

The rookie backstop notched his third career performance with four or more RBI, upping his season total to 68. Baldwin topped Atlanta's scoring with a 378-foot, two-run shot off reliever Orlando Ribalta in the ninth. The 24-year-old is now slashing .268/.337/.439 with 16 homers across 395 total plate appearances.

Davis is absent from the lineup for Monday's contest against the Cubs.

Davis will yield to Joey Bart at catcher for the second day in a row. The two have split playing time behind the dish the month, with Davis receiving seven starts to Bart's six.

The Nationals announced Monday that Ruiz (concussion) will continue to participate in baseball activities this week, though it's unclear if he'll return from the 7-day injured list before the end of the season, Spencer Nusbaum of The Washington Post reports.

The organization will likely wait and see how Ruiz fares in his workouts over the next few days before deciding on his next steps. Ruiz is the midst of his second stint on the injured list due to concussions and was pulled off a rehab assignment earlier this month after experiencing renewed symptoms.

Pages is out of the lineup for Monday's game against the Reds, John Denton of MLB.com reports.

Pages had made starts behind the plate in four of the Cardinals' previous five games, but he'll take a seat as St. Louis opens a three-game set with one of its divisional rivals. Jimmy Crooks will handle catching duties Monday.

Salas (back) was recently cleared to resume baseball activities at the Padres' spring training complex and will be one of the San Diego prospects who is set to participate in the Arizona Fall League, which begins Oct. 6., MLB.com reports.

Salas remains on Double-A San Antonio's 60-day injured list and doesn't appear in line to return to action over the final week of the Texas League season, but the young backstop looks like he could be ready to play at some point during the AFL, which runs through mid-November. Even if Salas hasn't progressed enough in his recovery from a lower back stress reaction to see action by the end of AFL play, he'll likely take part in winter ball to make up for the at-bats he lost out on this season. Salas' last appearance with San Antonio came back on April 17.

McCann went 2-for-4 with a home run and four RBI in Sunday's 6-4 victory at Minnesota.

The veteran backstop gave his team a 4-2 lead with a 407-foot, three-run blast off Twins starter Bailey Ober in the fourth. McCann is playing sparingly in a backup role with the Diamondbacks, slashing .258/.330/.423 with four homers, 15 runs scored and 13 RBI across 109 plate appearances this season. Unless anything happens to Adrian Del Castillo or Gabriel Moreno, the 35-year-old is not fantasy relevant.
