Cardinals Rookie Joshua Báez Makes MLB History With Three-Homer Debut
St. Louis Cardinals rookie Joshua Báez produced one of the most extraordinary MLB debuts in baseball history Saturday, hitting three home runs in his first three major-league at-bats and helping the Cardinals defeat the Chicago Cubs 8-4 at Wrigley Field.
Báez, 23, became the first player in Major League Baseball history to hit three home runs in his first three at-bats of a career. The performance immediately transformed what was supposed to be a promising debut into an unprecedented moment in the sport.
The Cardinals called Báez up from Triple-A Memphis earlier Saturday, and he wasted almost no time demonstrating why the organization considered him one of its top prospects.
His first major-league at-bat came against Cubs starting pitcher Matthew Boyd.
Báez took the very first pitch he saw in the majors and sent it deep into the center-field bleachers.
The blast traveled approximately 449 feet and immediately announced his arrival on the biggest baseball stage.
Rather than settling down after his spectacular first at-bat, Báez returned to the plate later in the game and homered again.
His second home run came in the fourth inning, this time sending the ball into the left-field seats.
The third homer followed in the sixth inning, when Báez drove another pitch into right field.
The three home runs came to three different parts of the ballpark, demonstrating the all-fields power that has made Báez such an intriguing prospect.
He finished the game with five runs batted in and helped the Cardinals establish control of a game that eventually ended in an 8-4 St. Louis victory.
Báez’s historic performance was especially remarkable because of how quickly he accomplished it.
He did not need several games to adjust to major-league pitching.
Instead, he homered on the first pitch of his career and then followed it with two more home runs in his next two plate appearances.
According to MLB records, no player had previously hit three home runs in a major-league debut.
The achievement immediately placed Báez among the most memorable debut performances in baseball history.
The young outfielder had already been producing impressive numbers in the minor leagues before receiving his promotion.
Báez entered the majors after leading Triple-A in home runs, with 34 homers in 103 games for Memphis.
He also had 90 RBIs and 21 stolen bases during his Triple-A campaign, showing that his game involved more than simply power hitting.
The Cardinals selected Báez in the second round of the 2021 MLB Draft after he graduated from high school.
The organization has spent several years developing his abilities, and his performance at Triple-A eventually earned him a major-league opportunity.
That opportunity could hardly have gone better.
Báez was inserted into the Cardinals’ lineup as the team’s fifth hitter and started in left field.
The circumstances of his debut were also notable because the Cardinals were playing at one of baseball’s most historic venues.
Wrigley Field has hosted generations of legendary players, and Báez immediately added his name to the stadium’s long list of unforgettable individual performances.
His first homer sent the Cardinals’ dugout into celebration.
By the time the third ball left the park, even the opposing crowd recognized that it was watching something extraordinary.
The Cardinals entered the game attempting to strengthen their position in the National League playoff race.
St. Louis had been hovering around the .500 mark and was chasing a postseason spot, making the victory particularly valuable.
Báez’s offensive explosion provided a major boost as the Cardinals continued their push.
Chicago attempted to fight back.
Michael Conforto hit a three-run homer that briefly brought the Cubs level, but St. Louis regained control and eventually pulled away.
Báez’s third home run helped give the Cardinals a three-run advantage, and the team added additional insurance before closing out the victory.
Pitcher Michael McGreevy also played an important role for St. Louis, earning the win after delivering a strong performance on the mound.
For the Cubs, the loss was particularly frustrating because Boyd surrendered all three of Báez’s home runs.
The veteran left-hander had entered the game as one of Chicago’s established pitchers, but Báez repeatedly found ways to punish him.
The rookie demonstrated his ability to handle different types of pitches, hitting a fastball for his first homer, a changeup for his second and a slider for his third.
That variety made the performance even more impressive.
Báez did not simply capitalize on one mistake or one type of pitch.
He adjusted to different offerings and continued to drive the ball with authority.
His historic debut also came after a lengthy development process.
The Cardinals drafted him out of high school in 2021, and he gradually progressed through the organization’s minor-league system.
There were challenges along the way, including injuries and inconsistent offensive stretches.
But Báez appeared to make significant progress during the 2025 season and carried that improvement into 2026.
His Triple-A numbers ultimately forced the Cardinals to give him an opportunity.
Now, after one game, the organization has every reason to be excited about what comes next.
Cardinals manager Oliver Marmol praised Báez’s performance after the game, noting the energy and excitement the young player brought to the clubhouse.
Báez himself described the experience as difficult to put into words.
For a player making his first appearance in the majors, the day represented the realization of a lifelong dream.
Few players ever get the opportunity to make their MLB debut.
Even fewer hit a home run in that debut.
Báez hit three.
The accomplishment also placed him in a very small group of players who have hit their first three career home runs in the same game.
His three-homer performance therefore goes beyond a remarkable debut.
It represents one of the rarest combinations of power and immediate success in MLB history.
The Cardinals will now have to determine how best to manage their young star.
One spectacular game does not guarantee long-term success, and Báez will eventually face the adjustments that every rookie encounters.
Major-league pitchers will study his swing, identify potential weaknesses and attempt to prevent him from repeating Saturday’s performance.
Báez will have to prove that he can consistently produce against elite pitching.
But there is no question that he has made an unforgettable first impression.
The Cardinals also have several other young players they hope can form the foundation of the team’s future.
Báez’s emergence adds another powerful name to that group.
If he can continue developing, his combination of power, speed and athletic ability could make him an important part of St. Louis’ lineup for years to come.
For now, however, Báez can simply enjoy a debut that will be remembered forever.
He became the first player in MLB history to hit three home runs in his first three at-bats.
He drove in five runs.
He helped the Cardinals beat the Cubs 8-4.
And he accomplished all of it at Wrigley Field in his first major-league game.
The Cardinals may have found an important piece of their future.
Joshua Báez certainly found a spectacular way to introduce himself to Major League Baseball.
Joshua Báez’s three-homer debut was the first of its kind in MLB history. The 23-year-old hit his first career home run on the first pitch he saw, then homered again in his second and third at-bats, driving in five runs as St. Louis defeated Chicago 8-4.
Báez was called up from Triple-A Memphis earlier Saturday after leading the minors with 34 home runs in 103 games, along with 90 RBIs and 21 stolen bases.
