Cardinals Notes: Arenado, Siani, Contreras, Nootbaar

Cardinals star Nolan Arenado departed the club’s win over the Giants in the eighth inning today due to discomfort in his left forearm, as noted by MLB.com’s John Denton. Notably, that’s not the same arm that Arenado suffered an elbow contusion on after being struck by a pitch from Marlins right-hander Huascar Brazoban earlier this week. More information was not made available following tonight’s game beyond the fact that Arenado would be evaluated further tomorrow.

It’s an unfortunate turn of events in the midst of what has been a difficult season for the 33-year-old veteran, who is slashing just .260/.315/.375 with a 99 wRC+. That would be Arenado’s first below-average offensive performance in a 162-game season since his rookie campaign back in 2013. He’s paired that lackluster offense with surprisingly pedestrian glovework at third base, where he’s been worth +0 Outs Above Average and -5 Defensive Runs Saved. That’s a far cry from the fielding he offered at the position earlier in his career, when he won the NL Gold Glove award at third base in ten consecutive seasons from 2013 to 2022.

Even with that diminished production this year, however, the loss of Arenado would still be a tough blow for the Cardinals should he end up missing time due to his injury. Not only is he just two seasons removed from a campaign where he was a finalist for the NL MVP award, but the eight-time All Star is the club’s only clear solution at third base given the present construction of the lineup. While former top prospect Jordan Walker came up as a third baseman and is currently in the minors, the 22-year-old has struggled both in Triple-A and at the big league level this year and converted to the outfield full time last year making him an unlikely choice to take over for Arenado in the case of an injury.

Super-utility bat Brendan Donovan has played the hot corner at times, but he’s settled in as the club’s regular left fielder in the absence of Lars Nootbaar. It’s possible that Donovan could slide over to third base and open up left field for Dylan Carlson, but perhaps a more likely scenario would see the Cardinals rely more heavily on bench bats Brandon Crawford and Jose Fermin to fill in for Arenado at third. That’s especially true given the fact that center fielder Michael Siani also exited today’s game due to an injury, though Jeff Jones of the Belleville News-Democrat relayed after the game that x-rays on Siani’s ribs after he hit the ground hard on a diving play in the outfield came back negative. The 24-year-old appears to have avoided a major injury, but even a day-to-day issue would at least temporarily weaken the club’s outfield depth noticeably.

As for Nootbaar, the 26-year-old has been sidelined by an oblique strain since the end of May. Jones relays that he appears to be making progress in his rehab but the outfielder has not yet even begun to take batting practice, instead only hitting off a tee at this stage in the process. That would seem to indicate that Nootbaar, who will surely require a rehab assignment before he can return to action, isn’t going to be returning to the club’s positional mix any time soon to provide Marmol additional flexibility as he fills out the club’s lineup card in the wake of Arenado’s and Siani’s possible injuries.

One piece of good news for Cardinals fans is the impending return of star catcher Willson Contreras, who Marmol told reporters (including Jones) will catch seven innings for Triple-A Memphis tonight before DH’ing tomorrow’s game. As Jones notes, Contreras caught for the Redbirds yesterday and Marmol acknowledged that seeing how the 32-year-old held up after catching back to back games was the last major box the club needed to check regarding Contreras’s rehab.

Contreras has been out since early May with a broken forearm and was initially expected to miss ten weeks due to the injury, but the backstop has long since clearly been ahead of that schedule and seems like he could factor into the club’s plans before the end of the month. The slugger posted an excellent .280/.398/.551 slash line in 31 games for the Cardinals this year before being sidelined by the injury and could provide a boost to an offense that has posted a collective wRC+ of just 95 to this point in the season.
