Joshua Báez delivered an unprecedented start to his major league career on August 15, 2026. The 23-year-old St. Louis Cardinals outfielder became the first player in Major League Baseball history to hit three home runs in his first three career at-bats during an 8-3 victory over the Chicago Cubs at Wrigley Field.
Promoted from Triple-A Memphis earlier in the week, Báez wasted no time making his presence felt, driving a 449-foot blast into center field on the very first big-league pitch he saw. He followed up with a solo shot in the fourth inning and a third round-tripper in the sixth, concluding his debut 3-for-3 with three runs scored and five RBIs.
Who Is Joshua Báez?
Joshua Emanuel Báez was born on June 28, 2003, in Boston, Massachusetts. He spent his early childhood in Santo Domingo, Dominican Republic, before his family settled in Boston’s Dorchester neighborhood.
Báez attended Cristo Rey Boston High School and Snowden International School before completing his prep career at Dexter Southfield School in Brookline, Massachusetts. As an amateur two-way player, he turned heads by touching 97 mph on the mound while maintaining a .442 batting average at the plate. His raw athletic profile earned him the 2020 Massachusetts Gatorade Baseball Player of the Year honors.
The St. Louis Cardinals selected Báez in the second round (54th overall) of the 2021 MLB Draft. To secure the powerful slugger, the Cardinals signed him for an over-slot bonus of $2.25 million, convincing him to forgo his college commitment to Vanderbilt University.
Path Through the Minors
Joshua Báez development across the Cardinals’ farm system required patience and mechanical refinement. He began his professional career in the Florida Complex League in 2021 and steadily climbed through Single-A Palm Beach, High-A Peoria, and Double-A Springfield.
A wrist injury limited his game action in 2022, and swing-and-miss tendencies challenged his progress through the lower rungs of the system. However, according to Baseball America’s scouting reports, Báez reworked his lower-half mechanics and posture during the 2024–2025 off-season to improve bat-to-ball contact.
The adjustments paid immediate dividends in 2025, where he slashed .287/.384/.500 with 20 home runs and 54 stolen bases between Peoria and Springfield. The Cardinals officially protected him by adding him to their 40-man roster on November 18, 2025.
2026 Triple-A Breakout with Memphis
Assigned to the Triple-A Memphis Redbirds to begin 2026, Báez established himself as one of the premier power threats in professional baseball. Over 103 minor league games before his promotion, he posted a .256 batting average, a .901 OPS, 34 home runs, 90 RBIs, and 21 stolen bases.
Key Minor League Highlights
- Four-Homer Game: On June 16, 2026, Báez hit four home runs against the Nashville Sounds, going 4-for-5 with seven RBIs to notch the first four-homer game in Memphis Redbirds history.
- Tape-Measure Power: On July 18, he belted a 473-foot grand slam against the Iowa Cubs.
- Top Prospect Standing: Entering the summer, MLB Pipeline listed Báez as the Cardinals’ No. 3 prospect and No. 59 overall in baseball.
A Debut for the MLB Record Books
Cardinals manager Oliver Marmol named Báez to the starting lineup as the starting left fielder, batting fifth against the rival Cubs at Wrigley Field.
| Plate Appearance | Inning | Pitch Details | Outcome | Distance |
| 1st At-Bat | 1st | 93.4 mph fastball (0-0 count) | 2-Run Home Run | 449 feet (108.6 mph exit velocity) |
| 2nd At-Bat | 4th | 3-2 changeup | Solo Home Run | 382 feet |
| 3rd At-Bat | 6th | Breaking ball in zone | 2-Run Home Run | 405 feet |
While previous major leaguers have homered in their first two career at-bats, Báez is the sole player in MLB history to go deep in each of his first three career plate appearances.
Player Profile and Long-Term Outlook
Standing 6-foot-3 and weighing 220 pounds, Joshua Báez possesses an imposing physical frame with plus-plus raw power (60–70 grade on the 20-to-80 scouting scale). His background on the mound translates into plus arm strength (60-grade), making him an asset in either corner outfield position. Furthermore, his combined 75 stolen bases across 2025 and 2026 highlight elite baserunning instincts for a power hitter.
The main area of focus remains pitch recognition. As detailed in Joshua Báez’s minor league career stats on Baseball-Reference, he accumulated 136 strikeouts in 103 Triple-A games in 2026. Sustaining success in St. Louis will depend on how effectively he adapts to breaking balls outside the strike zone once major league pitching staffs adjust to his power.
