Early Life and Background
Sebastián Rivero was born on November 16, 1998, and is identified as Venezuelan. Public records available in team and league reporting list his nationality and date of birth, and he entered professional baseball through international free agency.
Rivero signed with the Kansas City Royals as an international free agent early in his teenage years and began his professional career in the Royals’ developmental system. He progressed through complex-level and rookie ball assignments as part of the Royals’ minor league pipeline before advancing to full-season affiliates.
Path to Baseball
Rivero advanced steadily through the Royals’ minor-league ladder after his signing, appearing in Dominican Summer League and Arizona League rosters in his first professional season. He moved through rookie ball and single-A clubs, accumulating playing time and plate appearances that set the stage for higher-level assignments.
Across subsequent seasons Rivero reached Single-A and High-A affiliates and earned opportunities at the Triple-A level. His steady progression through multiple minor league levels positioned him for addition to a protected major league roster and eventual MLB promotion.

Kansas City Royals Breakthrough (2020–2022)

He was promoted to the major leagues for the first time in May 2021 and made his MLB debut on May 8, 2021, as the starting catcher against the Chicago White Sox. That promotion marked his first appearance on an active major league roster after years in the Royals’ minor league system.
Rivero spent time between Triple-A Omaha and the Royals’ active roster through the 2021 and 2022 seasons. He returned to Omaha in 2022 and received a second promotion to the majors in July 2022. The Royals designated him for assignment in November 2022 and placed him on unconditional release waivers later that month, concluding his initial tenure with Kansas City.
Chicago White Sox and Atlanta Braves Tenures (2022–2024)
Following his release from Kansas City, Rivero signed a minor league contract with the Chicago White Sox in December 2022. He split the 2023 season between Double-A Birmingham and Triple-A Charlotte, appearing in 73 combined games and batting .219 with four home runs and 28 RBI before electing free agency in November 2023.
Rivero then signed a minor league contract with the Atlanta Braves organization in November 2023. In 2024 he split time between Double-A Mississippi and Triple-A Gwinnett, appearing in 75 games and hitting .186 with one home run and 26 RBI. He elected free agency following the 2024 season.
Los Angeles Angels Era (2025–Present)

He made 11 major league appearances for Los Angeles in 2025, going 6-for-33 (.182) with two RBI and one stolen base. The Angels non-tendered Rivero in November 2025, and he re-signed a minor league contract with the club in December 2025. The Angels called him back to the active roster in April 2026 following an injury to another catcher.

Other Wins & Perfromances

2025 Season Performance
