The Cardinals are set to activate outfielder Dylan Carlson from the 10-day injured list tomorrow, according to The Athletic’s Katie Woo. Catcher Pedro Pages is expected to be optioned to Triple-A in the corresponding move. Woo also relays that left-hander Matthew Liberatore is expected to move from the bullpen to the rotation to take the ball in tomorrow afternoon’s game against the White Sox.
Carlson, 25, appeared poised to enter the season as the everyday center fielder in St. Louis until a sprained AC joint in his left shoulder sidelined him just before Opening Day. In his absence, the Cardinals have scuffled to a 15-18 start that leaves them just half a game out of last place in the NL Central. Much of those struggles can be attributed to a lack of offense from the club’s lineup, which has posted a collective 86 wRC+ that ranks sixth from the bottom in the majors. That figure has been dragged down by brutal offensive production from the club’s outfield mix, which to this point in the season has consisted of a combination of Lars Nootbaar, Brendan Donovan, Jordan Walker, Alec Burleson, Victor Scott II, and Michael Siani. With Donovan’s 92 wRC+ leading the pack, Cardinals outfielders have combined for a paltry slash line of .188/.268/.294 with an NL-worst wRC+ of 66.
Given those significant struggles, Carlson’s return to action is welcome news for fans in St. Louis even as he himself is far from a sure thing offensively. The club’s first-round pick in the 2016 draft, Carlson was a consensus top-20 prospect in the sport when he reached the majors during the shortened 2020 season and earned a third-place finish in NL Rookie of the Year voting during his first full campaign the following year. While he hit a solid .266/.343/.437 in 149 games that year, he’s struggled to repeat that production over the past two seasons. Since the start of the 2022 campaign, Carlson has slashed just .230/.316/.364 with a below-average 94 wRC+ in 204 combined games. Still, those numbers are at least decent for a center fielder and would represent a major upgrade over the club’s current production at the position, where is hitting .182/.280/.227 with a wRC+ of 56.
As for Liberatore, the 24-year-old has performed admirably in 12 appearances out of the bullpen this season with a 2.76 ERA in 16 1/3 innings, but a lackluster 16.4% strikeout rate and a much higher 4.18 FIP suggest that the lefty’s solid results have benefited from good fortune. While those questionable peripherals aren’t necessarily a reason for the Cardinals to avoid using him in the rotation, starting Liberatore is nonetheless a confusing choice given the lefty hasn’t thrown more than 38 pitches in a game since March and has struggled badly in the role throughout his major league career with a 5.72 ERA through 18 starts.
It’s not yet clear if Liberatore’s move to the rotation is a sign that he’s the club’s long-term replacement for veteran lefty Steven Matz, who is reportedly expected to miss at least “a couple of weeks” with a lower back strain, or if Liberatore’s start tomorrow will merely be a spot start before he passes the baton to one of the club’s other options, such as southpaw Zack Thompson or prospect Sem Robberse. Thompson made two starts for the club earlier this season but was optioned to Triple-A after allowing ten runs in 3 1/3 innings of work following a move to the bullpen, while Robberse has dominated Triple-A to the tune of a 1.77 ERA in six starts but has yet to make his major league debut.
