Joshua Báez homered in his first three MLB at-bats for the Cardinals

Joshua Báez homered in his first three major-league at-bats Saturday, CBS Sports reported, as the Cardinals defeated the Cubs in a debut that places the rookie in rarefied company.

The feat — three home runs in a player's first three trips to the plate — has occurred only a handful of times in the sport's history, a convergence of timing, adrenaline, and the particular cruelty of trying to throw strikes to someone with nothing to lose.

What happened

Báez homered three times in his debut for St. Louis on Saturday against Chicago, per the report. Each home run came in his first three at-bats, a distinction that separates the performance from the more common multi-homer debut. The Cardinals won the game.

The report did not specify the inning of each home run, the pitchers Báez faced, or whether the homers were solo shots or came with runners on base. It also did not detail Báez's position, his place in the batting order, or whether he recorded any additional at-bats beyond the first three.

Why it matters

A three-homer debut is not merely rare — it is a statistical outlier so extreme that it functions as its own category in the record book. Most players spend their first game adjusting to big-league velocity, pitch mix, and the simple fact of standing in a batter's box under lights they have never seen before. Báez skipped that adjustment entirely.

The performance also arrives at a moment when the Cardinals, sitting at .500 and 16.5 games behind in the National League Central, are evaluating their roster through the final weeks of the season. A debut of this magnitude does not guarantee future success — baseball history is littered with players who peaked in their first week — but it does establish Báez as someone the organization will watch closely.

The timing matters operationally, too. With rosters expanding to 28 players on September 1, the Cardinals will have additional flexibility to carry Báez and see whether the debut was an anomaly or a signal. The next two weeks will determine whether he remains in the lineup or returns to the minors for further seasoning.

Where the club stands

St. Louis is 72-72, a .500 mark that reflects a season spent treading water rather than climbing. The Cardinals are 16.5 games back in the NL Central, third in the division, a deficit that has long since moved the front office's focus from contention to evaluation. The Wild Card remains mathematically alive — they are 4.5 games out of the final spot — but the path requires a run the club has not yet shown it can sustain. The club is riding a one-game winning streak following Saturday's victory.

The Cardinals face the Cubs on Sunday at Wrigley Field, with Hunter Dobbins slated to pitch opposite Edward Cabrera. Monday brings games in Cincinnati against the Reds at Great American Ball Park, with Quinn Mathews and Andre Pallante scheduled to pitch against Kent Emanuel and Rhett Lowder, respectively. The schedule is unforgiving: three games in two days, all on the road, all against division opponents who have their own September agendas.

Báez's debut injects a new variable into that equation. Whether he plays Sunday is not yet known, but the Cardinals will need to decide quickly how much playing time to allocate to a player who just announced himself in the loudest possible way.

What we don't know yet

The report did not include Báez's defensive position, his spot in the batting order, or the specifics of each home run — inning, pitcher, count, or situation. It also did not clarify whether Báez had additional at-bats beyond the first three, or whether he played the entire game.

His roster status before the call-up was not detailed, nor was the corresponding move the Cardinals made to add him to the active roster. Whether Báez was on the 40-man roster or required a spot to be cleared is not yet public.

The Cardinals have not announced their lineup for Sunday's series finale, so it is unclear whether Báez will play or whether the club will rotate him into the lineup more gradually. The Monday games add another layer of uncertainty: the Cardinals will need to balance giving Báez at-bats with managing the rest of the roster through a compressed schedule.

What to watch

The immediate question is whether Báez plays Sunday at Wrigley Field. A three-homer debut typically earns a player another appearance, but the Cardinals may also weigh his workload against the Monday games and the need to keep other regulars fresh.

Beyond the next few days, the Cardinals will need to decide how much playing time Báez receives through the end of August and into September. The roster expands to 28 players on September 1, which gives the club more flexibility to carry Báez without sacrificing depth elsewhere. But playing time is finite, and the Cardinals have other young players they are evaluating.

The other variable is performance. A three-homer debut is a headline, but it is also a single game. The league will adjust, pitchers will study video, and Báez will face a different set of challenges in his second week than he did in his first at-bat. How he responds to that adjustment — whether he continues to hit for power, whether he can handle breaking balls away, whether he can defend his position consistently — will determine whether this debut was the start of a career or a story the Cardinals tell for years about a player who peaked on day one.

The Cardinals play Sunday at Wrigley Field, then travel to Cincinnati for Monday's games. The next two weeks will clarify whether Báez is a September story or a long-term answer.
