In the entire recorded history of Major League Baseball — a sport with data stretching back over 120 years — no player had ever hit three home runs in his very first big-league game. Until Saturday. Joshua Báez stepped into the batter’s box at Wrigley Field for the first pitch of his MLB career and turned in a debut so absurd that even seasoned baseball historians struggled to find a real comparison. Here’s everything you need to know about the 23-year-old St. Louis Cardinals outfielder who just made history — his height, weight, age, family, background, and the full story of the single greatest debut in the sport’s modern record-keeping era.

The Historic Debut: What Actually Happened
On Saturday, August 15, 2026, Joshua Báez was called up from Triple-A Memphis and inserted directly into the Cardinals’ starting lineup as their left fielder against the Chicago Cubs at Wrigley Field. What happened next has never occurred before in the history of the sport.
First at-bat: Facing Cubs starter Matthew Boyd, Báez smashed the very first pitch he saw in the majors an estimated 449 feet into the left-center field bleachers. It was the third-longest home run ever hit in a player’s MLB debut since ESPN began tracking home run distances in 2006 — trailing only Jason Heyward’s 476-foot blast in 2010 and Aaron Judge’s 457-foot shot in 2016. The homer also made Báez the first St. Louis position player in franchise history to go deep on the very first Major League pitch he ever saw.
Second at-bat: Facing Boyd again in the third inning, Báez worked a full count before ripping a changeup 382 feet down the left-field line for a solo shot, putting the Cardinals up 4-3. That made him just the ninth player in MLB history to homer twice in his first regular-season game, and only the second player since 1900 to homer in each of his first two career at-bats in a single game — joining Bob Nieman, who accomplished the feat on September 14, 1951.
Third at-bat: In the sixth inning, facing Boyd for a third time, Báez drove a 99.8 mph line drive the opposite way toward right field. For a moment, even Báez himself wasn’t sure it would clear the wall — but it did, completing a feat no player had ever accomplished: three home runs in three at-bats to open a Major League career.
His fourth and final at-bat of the day ended in a lineout to left field — the first out of his MLB career — but by then, the history had already been made. Báez finished the day 3-for-4 with five RBIs, and the Cardinals cruised to an 8-4 victory over the Cubs.
Major League Baseball confirmed Báez as the first player in modern baseball history (dating to 1901, when comprehensive game logs began) to hit three home runs in a debut. Given the sheer scale of MLB’s history — more than 23,752 players have appeared in a Major League game according to Baseball Reference — the rarity of the feat is difficult to overstate.
The Moment, In His Own Words
Cardinals manager Oliver Marmol didn’t hide his amazement afterward, admitting it’s rare for him to allow himself to step back and simply enjoy a moment like that during a game, but said Báez left him no choice but to take it in. Even Cubs manager Craig Counsell offered a tip of the cap after the game, acknowledging that Báez had turned around three different pitch types for three separate home runs — and that his team had simply been beaten by a historic effort.
For Báez himself, the day was overwhelming in the best possible way. He described the experience as feeling completely unreal — going from getting a hit in his first big-league at-bat to somehow tacking on two more home runs in the same game left him at a loss for how else to describe it, other than saying it felt crazy.
Thirty members of Báez’s family were in attendance at Wrigley Field to witness the moment, including his mother, Yris Carmen Báez, who was photographed embracing her son on the field after the game — an image that quickly went viral across sports media.
Who Is Joshua Báez?
Born June 28, 2003, in Boston, Massachusetts, Báez’s journey to the majors is as compelling as the debut itself. His family moved back to their native Santo Domingo, Dominican Republic, when he was just an infant, and he was raised there before the family returned to the Dorchester neighborhood of Boston when he was around 11 years old, entering sixth grade. Having grown up primarily speaking Spanish, Báez had to learn English largely on his own after the move — a challenge he met by becoming an honor student at a highly competitive private school within just a couple of years.
His path through Boston’s competitive prep and travel-ball circuit became the stuff of local legend well before his MLB draft year. He first connected with the Next Level baseball program in the city at age 13, playing up against 19-and-under competition almost immediately. Christian Ortiz, the program’s founder, has described watching Báez transform physically over the following years — from around 160 pounds at age 13 to roughly 230 pounds by the time he signed with the Cardinals in 2021, a physical evolution built on what those around him have consistently described as an extraordinary, near-obsessive work ethic in the weight room.
Báez attended Cristo Rey Boston High School and Snowden International School before transferring to Dexter Southfield School in Brookline ahead of his junior year, where his production only continued to climb — by age 15, he was already 6-foot-3 and 205 pounds, with a fastball touching 98 mph on the mound in addition to legendary home run power at the plate. In 2020, he was named Massachusetts Gatorade Baseball Player of the Year.
Báez committed to play college baseball at Vanderbilt University, but that path changed when the St. Louis Cardinals selected him in the second round of the 2021 MLB Draft, 54th overall, signing him to a $2.25 million bonus straight out of high school instead.
Joshua Báez’s Height & Physical Profile
Báez is listed at 6 feet 3 inches (190 cm) and 220 pounds (100 kg), a big, physically imposing frame for an outfielder that’s translated directly into the kind of raw power that made Saturday’s debut possible. His scouting profile from MLB Pipeline grades his raw power at a 60 on the traditional 20-to-80 scouting scale — well above average — alongside a 60-grade arm, giving him a genuinely well-rounded physical toolset beyond just his home run power.
The Long Road Through the Minors
Báez’s path to the majors wasn’t a smooth, uninterrupted rise — it took him parts of five full seasons to get there, and along the way, there were real questions about whether his prodigious raw power would ever translate into consistent big-league-caliber contact.
- 2021: Made his professional debut with the Rookie-level Florida Complex League Cardinals shortly after being drafted, appearing in 23 games.
- 2022: Played just 32 games across Class-A Palm Beach and the FCL, a limited season.
- 2023: A difficult year by his own standards — 91 games with Class-A Palm Beach, batting just .218 with seven home runs, and striking out more than a third of the time during a second stint at that level, raising real concerns among evaluators about his contact ability.
- 2024: Began showing signs of progress, laying the groundwork for the breakout to come.
- 2025: The turning point. Báez played 117 games across High-A and Double-A Springfield, slashing .287/.384/.500 with 20 home runs, 79 RBIs, and 54 stolen bases — a genuine five-tool breakout that got the entire Cardinals farm system, and its fanbase, paying close attention.
- 2026 spring training: Hit .333 with three home runs in big-league camp before being optioned back to Triple-A Memphis to begin the season.
- 2026 (Triple-A Memphis): Entered his call-up leading all of Triple-A baseball in home runs (34), RBIs (90), and runs scored (79) — numbers that made his eventual promotion feel less like a matter of if than when.
In November 2025, the Cardinals had already added Báez to their 40-man roster specifically to protect him from the Rule 5 Draft, a clear signal of how highly the organization valued his long-term upside even before his historic debut confirmed it.
Joshua Báez’s Family
Báez’s father, Jose Manuel Báez, was himself an accomplished baseball and softball player and a significant influence on his son’s development in the sport. He passed away on June 16, 2023 — meaning he did not live to see his son’s historic MLB debut, a bittersweet undertone to Saturday’s achievement for those close to the family. Báez’s mother, Yris Carmen Báez, was present at Wrigley Field for the debut and was seen embracing her son emotionally on the field afterward, one of the most widely shared images from the entire day.
Is Joshua Báez Dating Anyone?
As of his historic debut, Báez is reported to be single and has not been publicly linked to anyone. He’s kept his personal life almost entirely out of the spotlight throughout his rise through the Cardinals’ farm system, with virtually all available reporting on him focused squarely on his development as a player.
Joshua Báez’s Net Worth
Báez’s net worth is currently estimated at around $1 million to $2 million, built primarily through his $2.25 million signing bonus from the Cardinals in 2021, along with minor league salaries over his five years in the organization’s system. With his contract now guaranteed at the Major League level following his call-up — and given the sheer magnitude of national attention his debut has generated — his earning potential, both through baseball salary and potential endorsement opportunities, is expected to grow rapidly in the immediate future.
What’s Next for Joshua Báez
Báez was already in the Cardinals’ lineup for the series finale against the Cubs the very next day, a nationally televised Sunday night matchup — giving him an immediate encore opportunity in front of an even larger audience than his historic Saturday debut. Entering his call-up as the Cardinals’ No. 3 overall prospect and MLB Pipeline’s No. 93 prospect league-wide, the expectation within the organization now is that Báez has firmly earned a real, extended look in the St. Louis outfield for the remainder of the season.
Why This Debut Is Such a Massive Story
A few things make Báez’s performance resonate well beyond a typical highlight-reel moment:
It’s a genuinely unprecedented record. With over 23,000 players having appeared in MLB history, going the entirety of the sport’s recorded existence without a three-homer debut — and then having someone finally do it — is the kind of achievement that instantly becomes part of the sport’s permanent historical record.
The emotional family context adds real weight. Báez achieving this milestone in front of 30 family members, without his late father able to witness it, has resonated deeply with fans well beyond typical box-score coverage.
His backstory is a genuine underdog arc. From learning English after relocating from the Dominican Republic as a preteen, to grinding through four rocky minor league seasons before his 2025 breakout, Báez’s path to Saturday’s debut adds real substance to what could otherwise have been just a statistical anomaly.
The timing amplifies everything. Coming during a tight National League playoff race, with the Cardinals in the thick of postseason contention, Báez’s debut wasn’t just a personal milestone — it was an immediate, tangible boost to a team fighting for October baseball.
