Cardinals manager Oli Marmol noted Tuesday that Knizner is not assured of the team's backup catcher role, John Denton of MLB.com reports.

EDGE Analysis

Knizner served as the primary understudy to Yadier Molina over the last two seasons, but he holds just a .204/.292/.288 career batting line in 553 plate appearances at the major-league level. Tres Barrera has impressed the Cardinals' coaches and pitchers this spring, per Denton, and might emerge as the No. 2 option behind Willson Contreras.

Knizner agreed to a one-year, $1.1 million contract with the Cardinals on Friday to avoid arbitration, Derrick Goold of the St. Louis Post-Dispatch reports.

EDGE Analysis

Knizner appeared in a career-high 97 games last season and had a .215/.301/.300 slash line with four home runs and 25 RBI. He'll remain the No. 2 catcher despite the retirement of Yadier Molina since the Cardinals signed Willson Contreras in free agency.

Knizner went 2-for-4 with a solo home run in Wednesday's loss against the Brewers.

EDGE Analysis

Knizner led off the seventh inning with a homer off righty reliever Matt Bush to cut the Cardinals' deficit to one. The catcher's last 14 games have been abysmal at the plate as he's recorded a .098 average and .268 slugging percentage over 41 at-bats. However after a recent 0-for-19 stretch , the 27-year-old has homered in back-to-back contests.

Knizner went 1-for-4 with a two-run home run in Tuesday's win over the Brewers.

EDGE Analysis

Knizner connected for a two-run shot off Brent Suter in the top of the fourth frame, extending the Cardinals' lead to 4-0. The homer was his third of the season and first since Aug. 27. Since the beginning of September, Knizner has gone 2-for-36 with a home run, a double, two RBI and two runs scored while striking out 10 times.

Knizner went 1-for-2 with a two-run home run and a hit-by-pitch in Saturday's 6-5 win over Atlanta.

EDGE Analysis

Knizner has hit safely in five straight games, going 7-for-16 (.438) with a homer, three RBI, eight runs scored and a pair of doubles in that short but productive stretch. He accounted for the Cardinals' first two runs in this contest. The catcher has alternated starts with Yadier Molina over the last six games, which suggests Knizner may be forcing his way into a timeshare. He has a .231/.329/.302 slash line with two homers, 22 RBI, 23 runs scored and eight doubles through 229 plate appearances this year.

Knizner will return to the bench for Monday's game against the Cubs, Bally Sports Midwest reports.

EDGE Analysis

With Yadier Molina (personal) coming off the restricted list Monday and stepping back in as the Cardinals' No. 1 catcher, Knizner's brief run atop the depth chart comes to an end. Knizner was behind the plate for both of the Cardinals' final two games of the weekend series in Arizona and went 3-for-7 with a double, two walks and four runs.

Knizner went 2-for-4 with a double, a walk and three runs scored in Saturday's 16-7 win over the Diamondbacks.

EDGE Analysis

Knizner got the start behind the dish Saturday as Yadier Molina (personal) is away from the team. In his last 10 games, Knizner has delivered four multi-hit efforts with two doubles, two RBI and seven runs scored. The backup catcher is up to a .219/.311/.273 slash line with one home run, 19 RBI, 18 runs scored and seven doubles through 213 plate appearances this year. Molina is expected to rejoin the Cardinals on Monday, so Knizner's time as the No. 1 backstop is likely limited.

Knizner is out of the lineup for Tuesday's game against the Cubs, Jeff Jones of the Belleville News-Democrat reports.

EDGE Analysis

With Yadier Molina (knee) back from the 10-day injured list and stepping into the lineup Tuesday, Knizner is expected to serve as St. Louis' No. 2 backstop moving forward. Knizner finally started to find a rhythm at the plate in July with a .280/.345/.320 slash line on the month, but he's still holding down a poor .575 OPS over 194 plate appearances on the season.

Knizner is out of the lineup for Sunday's game against the Nationals.

EDGE Analysis

Knizner will get a much-needed breather after he started behind the plate in each of the past six games. Austin Romine will relieve Knizner of catching duties in the series finale, but both players are likely to settle into reserve roles as soon as Tuesday, when No. 1 backstop Yadier Molina (knee) is expected to be activated from the injured list.

Knizner isn't starting Friday against the Reds, John Denton of MLB.com reports.

EDGE Analysis

Knizner drew starts in five of the last six games and went 7-for-15 with a double, five RBI and a run. Austin Romine is starting behind the plate and batting ninth.
