St. Louis Cardinals Prepare for Potential JJ Wetherholt Debut
The St. Louis Cardinals are gearing up for a potential MLB debut for top prospect JJ Wetherholt, with the team's series against the Pittsburgh Pirates in late August potentially marking a significant milestone.
The decision to call up Wetherholt would be influenced by a combination of factors, including his performance, the team's roster needs, and MLB regulations regarding rookie eligibility and prospect promotions.
Player Performance & Development
The Cardinals will assess Wetherholt's readiness based on his minor league performance, consistency, and ability to contribute at the MLB level. If he demonstrates he can succeed against higher-level competition, a call-up could be on the horizon.
Roster Needs and Team Injuries
Injuries or a need to bolster depth in certain positions could accelerate Wetherholt’s call-up.
MLB Rookie Eligibility and Service Time Rules
Prospects must meet specific criteria to maintain rookie status and be eligible for promotion incentives. Wetherholt must have fewer than 60 days of prior MLB service and appear on at least two of three Top 100 prospect lists (MLB Pipeline, Baseball America, ESPN) to qualify for these considerations.
Timing of Potential Debut
While the exact promotion date depends on team circumstances, prospect promotions tend to occur later in the season, particularly in late August or September. This aligns with typical patterns seen for other highly ranked prospects.
Potential Debut Date
The potential date for Wetherholt's MLB debut could be the Monday night series opener against the Pittsburgh Pirates on August 25th, 2023.
Playing Time Dilemma
The playing time dilemma in the Cardinals' lineup could complicate matters if Wetherholt is added to the mix. If Nolan Arenado is healthy, he may take playing time away from Wetherholt upon his debut.
Long-Term Outlook
Wetherholt is seen as the centerpiece of the Cardinals' young core long-term, and he is viewed as a top 5 prospect by some scouting outfits. If he maintains rookie eligibility, he is a strong candidate to win Rookie of the Year for the Cardinals in 2026.
The club may want to see Wetherholt "fail" and rebound before making his way to St. Louis, as they did with Masyn Winn, who made his MLB debut with the Cardinals on August 18th, 2023. Nolan Arenado is currently in Jupiter, aiming to return around the same time as Wetherholt's potential debut.
The Cardinals should prioritize setting up Wetherholt for future success over gathering information on other key position players. The best way for Wetherholt to play every day upon his debut and maintain rookie eligibility is to have him debut in late August. To maintain rookie eligibility, prospects must not accumulate more than 130 at-bats before September 1st of any season.
