Joshua Báez Shines in Major-League Debut with Three Home Runs

Joshua Báez, with a broad smile, climbed the steps at Wrigley Field to greet over 30 friends and family after his remarkable major-league debut for the St. Louis Cardinals. It was a debut that stood out in baseball’s extensive history. No one could have predicted such a performance as Báez hit three home runs in his first three at-bats, securing an 8-4 win over the Chicago Cubs. Even the light rain seemed to enhance the memorable atmosphere.

Báez, now 23, was born in Boston, then moved to the Dominican Republic, his family’s origin. Returning to Massachusetts, he learned English and attended Dexter Southfield, a school near Fenway Park. While working as a delivery driver for DoorDash, he pursued baseball and promised his late father to reach the major leagues.

During the Saturday game, Báez played left field and was followed by a buzzing bee, which he took as a sign of his father’s presence, further making the day unforgettable. Cardinals manager Oli Marmol, acknowledging Báez’s mother, spoke of the support needed to reach the top.

You need a strong support group to navigate the ups and downs of this game. I told his mom to savor this special day for as long as she wanted.

The event, although appearing like an overnight success, underscored Báez’s determination. His family and friends celebrated with a chant, while the Cardinals explored his capabilities.

Báez first caught the Cardinals’ attention in 2020. Despite pandemic restrictions, his power and athleticism stood out. In 2021, the Cardinals selected him with the second-round pick, paying a $2.25 million signing bonus. His standout ability to hit across fields distinguished him. Yet, his journey was fraught with challenges, including a wrist injury and high strikeout rates in the minors.

In 2024, the Cardinals worked to overhaul his swing. He trained in Jupiter, Fla., focusing on improving contact while retaining power. The adjustments bore fruit when his strikeout rate improved without affecting his power.

Báez’s perseverance paid off, culminating in a championship victory in Double-A baseball in 2025. Entering 2026 as a top prospect, his debut was highly anticipated. On eventful Saturday, Cardinals bench coach Daniel Descalso humorously proposed pulling Báez for defense after his third home run.

Marmol, drawing parallels to witnessing Albert Pujols’ historic home run, witnessed the crowd’s lively energy. Recently joined by advisor-turned-executive Chaim Bloom, the Cardinals’ development system is rejuvenating under their new leadership.

The successful debuts of young talents like Jordan Walker and Masyn Winn further amplified the franchise’s optimism. Blooms’ leadership accelerated the Cardinals’ rebuilding process as Báez looks to join this emerging core.

Báez’s performance in his debut showed his diverse talent by hitting various pitches to different parts of the field against seasoned pitcher Matthew Boyd. His adaptability became evident, as noted by Descalso.

Enduring struggles and achieving goals is key, and now, it’s about making the right adjustments to stay in the league.

Following his explosive debut, Báez faced challenges, going 0-for-5 in Sunday’s game. Still, the Cardinals’ performance overall kept them competitive in the playoff race, invigorated by Báez’s presence.
