Every Major League dream starts somewhere. For many of baseball’s top international prospects, that journey begins in the Dominican Summer League.
The Rookie-level circuit opened its 2026 season today, providing an early glimpse at the next generation of baseball talent. Widely regarded as the first professional step for many international signees, the league serves as a critical part of Major League Baseball’s player development pipeline.

The Dominican Summer League’s 30 clubs compete primarily at team-operated academies throughout the country, with games played at training complexes in Boca Chica, Guerra and San Cristóbal. The season runs from June through mid-August, introducing young players to the demands of a professional schedule and the expectations that come with pursuing a career in baseball.
Rosters are composed primarily of international prospects between the ages of 17 and 22, including many 16-year-olds making their professional debuts after signing during MLB’s international free agent signing period. All 30 Major League organizations operate at least one DSL affiliate, while several clubs field multiple teams to accommodate growing international development programs.
This year’s Opening Day rosters feature many of the game’s most highly regarded international signees and emerging prospects. Among the players to watch are Venezuelan catcher Fernando Graterol and Venezuelan outfielder Sebastian Romero in the White Sox organization, along with Phillies prospect Francisco Renteria.
The Dominican Summer League has served as the starting point for numerous major league careers. Many of today’s established stars first developed their skills on academy fields in the Dominican Republic before advancing through the minor leagues. While most players opening the season will remain largely unknown to fans, the league has a long history of helping transform promising international talent into future major leaguers.
Beyond competition, the league provides a unique developmental environment. By training and competing at their organization’s academy in the Dominican Republic, prospects can continue their growth in familiar cultural surroundings before eventually transitioning to the United States and higher levels of the minor leagues.
Player development remains the league’s primary objective. Coaches focus on refining fundamentals, improving baseball instincts and helping prospects build the skills necessary to advance through their organization’s system. While teams compete throughout the season, long-term growth often carries greater significance than the standings.
The Dominican Summer League features approximately 1,400 to 1,500 active players and serves as a key entry point for international talent. In recent years, international signing bonuses have continued to rise, with some of the top prospects receiving deals worth more than $1 million before ever appearing in a professional game.
As a result, organizations evaluate players through a much broader lens than traditional statistics. Scouts and player development staff prioritize athletic tools, physical projection and developmental progress when assessing young prospects.
For pitchers, evaluators look beyond velocity, focusing on mechanics, command and the ability to consistently throw strikes. Position players are assessed on traits such as bat speed, athleticism and defensive versatility. Organizations also place significant value on projectability, examining a player’s physical frame, capacity for future growth and ability to respond to coaching.
In a league built around development, the focus is not solely on where a prospect is today, but what he can become in the years ahead. For hundreds of young players taking the field this summer, the Dominican Summer League represents the first step toward a goal shared across professional baseball: reaching the Major Leagues.
While Opening Day marks the beginning of the Dominican Summer League season, it also marks the start of professional careers for hundreds of young players. Over the next several months, prospects will take their first steps along baseball’s developmental ladder, working to transform potential into opportunity. For many, the road ahead will be long and challenging, but each player begins the season with the same dream: one day reaching the major leagues.
