Knizner is not in the lineup for Game 2 of Wednesday's doubleheader against the Mets, Zachary Silver of MLB.com reports.

EDGE Analysis

Knizer started Game 1 and will head to the bench after going 0-for-3 with a strikeout. Ali Sanchez will take over behind the plate in the nightcap for the Cardinals.

Knizner, who's set to serve as the primary catcher for the time being with Yadier Molina (foot) on the injured list, went 2-for-4 with a run in a win over the Phillies on Tuesday.

EDGE Analysis

Knizner started both weekend games against the Reds in Molina's stead and provided similarly encouraging results, going 2-for-7 with a double and an RBI in that pair of games. Tuesday's multi-hit effort, his first of the season, pushed his slash to an impressive .304/.360/.391 across his first 25 plate appearances, and with Molina down at least the next 10 days, Knizner should be in for his most extensive big-league starting opportunity yet.

Knizner, making his first start of the season in Tuesday's win over the Nationals, went 1-for-3 with two walks and a run.

EDGE Analysis

Coming into the season, Yadier Molina was projected to cede starting duties behind the dish more often than in the past, but until Tuesday, the ageless veteran's hot bat had kept him in the lineup for each of the Cardinals' first 10 games. Knizner made good use of his opportunity, however, following a 1-for-4 start to the season as a pinch hitter/defensive replacement in three other contests.

Knizner, who went 2-for-3 with two runs in a Grapefruit League loss to the Nationals on Friday, is 4-for-8 with a double, two RBI and four runs overall across three spring games.

EDGE Analysis

Knizner finally appears to have a clear path to the primary backup role at catcher with veteran Matt Weiters, who effectively blocked him the last two seasons, no longer on the roster. Consequently, the 26-year-old's strong early start is reason for cautious optimism, especially since Knizner has a relatively extensive minor-league track record of success at the plate to support the notion he could thrive with extended opportunity. Through his first 75 major-league plate appearances over the last two seasons, Knizner has generated a .232/.280/.362 slash with five extra-base hits (three doubles, two home runs), 11 RBI, four walks, two steals and eight runs.

Knizner is preparing for the possibility of filling a variety of roles this coming season and has reported to spring training with a holistically impressive mindset, Zachary Silver of MLB.com reports. "Kiz has really done a nice job," manager Mike Shildt said. "He's off to a good start to camp, he's in a good place physically and mentally."

EDGE Analysis

The 26-year-old doesn't quite know whether he'll open the season back in the minors or as Yadier Molina's backup, but he dove into film study of late-inning game situations this offseason in an attempt to be better prepared for whatever comes his way. Knizner has also stepped up his immersion into scouting reports and has already familiarized himself with the Cardinals' first two scheduled opponents of the regular season, the Reds and Marlins. There's more talk than in previous springs of Molina operating in a legitimate timeshare behind the dish as the club prepares for an eventual future that doesn't include the 38-year-old backstop, and Knizner, with his 26 games of big-league experience and familiarity with the pitching staff, seems much more prepared to step in occasionally for Molina than offseason additions Ali Sanchez and Tyler Heineman.

The Cardinals added Knizner to their 28-man roster Wednesday ahead of the team's wild-card series with the Padres, Jeff Jones of the Belleville News-Democrat reports.

EDGE Analysis

Knizner is slated to serve as the Cardinals' No. 3 catcher behind Yadier Molina and Matt Wieters during the three-game series. The 25-year-old appeared in eight games during the regular season, going 4-for-16 with four RBI.

Knizner was optioned off the Cardinals' active roster Friday.

EDGE Analysis

Knizner had been filling in as the backup catcher with Matt Wieters out with a bruised toe, going 4-for-16 at the plate. He'll head back to the team's alternate training site now that Wieters is ready to return.

Knizner entered Tuesday's win over the Reds on Tuesday as a pinch hitter in the top of the sixth inning and went 2-for-2 with a two-run infield single and a run.

EDGE Analysis

The rarely-used catcher made the most of his playing time opportunity, extending the Cardinals' lead to 13-0 in the sixth inning with his single. Knizner has not logged any starts since Matt Wieters' went on the injured list Aug. 20 with a toe issue, and he has just 17 plate appearances on the season overall.

Knizner will be Matt Wieters' primary backup at catcher while Yadier Molina (illness) remains out of action.

EDGE Analysis

Knizner did not see any action over the first five games of the season and has primarily been serving as a bullpen catcher. He'll now ascend to the job of primary backup for the time being, which should afford him some opportunities behind the dish in coming games.

Knizner was named to the Cardinals' Opening Day roster on Thursday, Anne Rogers of MLB.com reports.

EDGE Analysis

The promising backstop showed enough in summer camp to finish making his case for a spot that could see him fill a few different roles. Knizner will be available off the bench, as an occasional spot starter in place of the aging top duo of Yadier Molina and Matt Wieters and as a bullpen catcher whenever needed. The Cardinals were intent on allowing Knizner to continue his development in a year without minor-league baseball, with president of baseball operations confirming that was one of the team's priorities.
