Leo Rivas Bio
Leonardo Andres Rivas is a Venezuelan professional baseball infielder for the Seattle Mariners of Major League Baseball. Rivas made his MLB debut in 2024 after signing with the Los Angeles Angels as an international free agent in 2014 and progressing through multiple minor league levels before reaching the major leagues.
Early Life and Background
Leonardo Andres Rivas was born on October 10, 1997, and holds Venezuelan nationality. He signed with the Los Angeles Angels as an international free agent on July 11, 2014, beginning a professional career that would take him through rookie and single-A levels in the Angels system and beyond.
Rivas began professional play in 2015 with the Dominican Summer League Angels and moved through short-season and full-season affiliates during his development. Early minor-league seasons established his profile as a contact-oriented middle infielder with speed, drawing attention for on-base ability and base-stealing potential in development leagues.
Path to Baseball
Rivas progressed through the Angels farm system from rookie ball to High-A between 2015 and 2019, appearing for teams including the Dominican Summer League Angels, Arizona League Angels, Orem Owlz and Burlington Bees. He earned recognition as a Pioneer League All-Star while with Orem and continued to demonstrate speed and plate discipline across multiple minor-league levels.
The cancellation of the 2020 minor league season interrupted many players’ trajectories, including Rivas, but he remained in organizational plans and was later identified as part of a trade package, which led to his move to the Cincinnati Reds system at the end of 2020. Those transitions set the stage for further progress through Double-A and Triple-A competition before reaching the major leagues with the Seattle Mariners.
Leo Rivas Career
Early Career (2015–2019)
Rivas made his professional debut in 2015 with the Dominican Summer League Angels and returned to the DSL in 2016 before advancing to the Arizona League Angels that summer. Across 2016 he posted strong on-base numbers and stole 26 bases between the two levels, signaling speed and patience as foundational tools in his game.
In 2017 Rivas split time between the Orem Owlz and the Burlington Bees and was named a Pioneer League All-Star for Orem after producing a combined line that showcased high on-base rates and stolen-base totals. He spent the 2018 and 2019 seasons with Burlington and the High-A Inland Empire 66ers respectively, compiling experience and incremental power while continuing to be a base-stealing threat.
Los Angeles Angels Development (2014–2020)
Signed in 2014 as an international free agent for a reported signing bonus, Rivas developed within the Los Angeles Angels organization through 2019, rising from the DSL to High-A competition. Over those seasons he demonstrated growth in plate discipline and maintained consistent stolen-base production, though power remained modest as he refined his defensive and offensive approach.
Rivas did not play in 2020 due to the cancellation of the minor league season, but his body of work through 2019 and subsequent readiness placed him as a player to follow during league realignments and roster transactions at the end of 2020.
