Cubs place OF on seven-day concussion IL

The Cubs announced this afternoon that they’ve placed outfielder Owen Caissie on the 7-day concussion-related injured list. Outfielder Kevin Alcantara was recalled from Triple-A to replace Caissie on the active roster.

The move comes just one day after the Cubs recalled Caissie to the big league roster and optioned Alcantara to the minors. Caissie started yesterday’s game against the Rays but exited the game after hitting his head against the outfield wall at Wrigley Field while making a catch. Manager Craig Counsell told reporters (including Vinnie Duber of the Chicago Sun Times) that Caissie was being put through the concussion protocol after yesterday’s game. Evidently, Caissie’s symptoms were severe enough that they opted to place him on the shelf and get him time to recover.

That decision well might bring Caissie’s first season in the big leagues to an end, depending on the severity of his concussion symptoms. If that’s the case, he’ll end 2025 with just 12 games and 27 plate appearances in the big leagues, during which he collected five hits (including a double and a homer) and one walk against eleven strikeouts. That cup of coffee pairs with a strong performance with Iowa this year, where he slashed .286/.386/.551 with 22 homers and 28 doubles in just 99 games. A consensus top-50 prospect in the game, Caissie could get a lot more runway with the Cubs come next season if Kyle Tucker departs the club via free agency in the offseason.

For now, however, his roster spot will go to Alcantara. A fellow top Cubs prospect generally viewed as sitting near the back of the league-wide top 100, Alcantara has appeared in just three games this year. He’s gone 1-for-7 with three strikeouts this year and figures to serve mostly as a bench piece for the Cubs in the coming weeks, though injuries could offer him more opportunities. Both Kyle Tucker and Seiya Suzuki are currently unavailable; Suzuki due to an illness that has left him day-to-day in recent days, and Tucker due to a calf issue that’s sent him to the injured list. Fellow top prospect Moises Ballesteros (7-for-28 with three extra base hits) is getting a look at DH at the moment, and that leaves right field open for some combination of Alcantara and Willi Castro until Suzuki is ready to return to games. Once Suzuki is back, Alcantara, Ballesteros, and Castro will all be competing for playing time until Tucker’s eventual return to the lineup.

That might not be for a while, as Counsell told reporters (including Sahadev Sharma of The Athletic) on Friday that Tucker returning as soon as he’s eligible to be activated on Tuesday is “unlikely right now.” Perhaps that stance could change in the coming days, but Tucker has not yet resumed running since he was placed on the injured list. While the Cubs aren’t in danger of losing their playoff spot at this point, getting the star’s 140 wRC+ bat back into the lineup with enough time for him to get settled in before the playoffs begin seems sure to be a top priority for the Cubs over the season’s final two weeks.
