Top 10 Youngest MLB Rosters For 2025 Season
It has been half a decade since the capitalās MLB team last tasted postseason glory. Will Washington Nationals odds improve in 2025?
Between 2020 and 2024, the Nats have bumbled through a stretch where the teamās average winning percentage was a woeful .410, as Washington finished last in the five-team National League East division four times before climbing to fourth in 2024.
With less than a month until Spring Training games start, BetVirginia.com was curious which teams are projected to have the youngest rosters in the MLB. We consulted FanGraphs.com for projected 40-man rosters, calculated the average age for each team and ranked the 10 youngest teams.

Top 10 Youngest MLB Rosters For 2025 Season
Rank | Team | Total Score |
1 | Miami Marlins | 26.19 |
2 | Washington Nationals | 26.71 |
3 | Cleveland Guardians | 27.12 |
4 | St. Louis Cardinals | 27.23 |
5 | Pittsburgh Pirates | 27.32 |
T6 | Chicago White Sox | 27.33 |
T6 | Tampa Bay Rays | 27.33 |
8 | Cincinnati Reds | 27.37 |
9 | Detroit Tigers | 27.41 |
10 | Colorado Rockies | 27.42 |
The Nationals made the most of their last trek to the playoffs in 2019, winning the clubās lone World Series championship in 2019 over the Houston Astros.
This year, things donāt look as rosy for Washington, at least according to the oddsmakers. Caesars Virginia Sportsbook gives Washington a preseason win total over/under of 71, to go with the second-longest odds of any team at winning the NL East, at +10000, ranking ahead of the miserable Marlins, who are listed at +20000.
Nationals Among MLBās Youngest Teams in 2025
As we speed our way towards Washingtonās Opening Day tilt against the Philadelphia Phillies inside Nationals Park on March 27, itās worth taking a gander at where the franchise ranks when it comes to on-field experience among the 30 teams in the majors.
Washingtonās average age is 26.71 years, according to the projected 40-man roster at FanGraphs.com, for a team that has +750 odds to make the postseason at bet365 Virginia Sportsbook. That is the second-youngest average behind the Marlins (26.19 years) and ranks ahead of the Cleveland Guardians (27.12), St. Louis Cardinals (27.23) and Pittsburgh Pirates (27.32).
The Chicago White Sox and Tampa Bay Rays (27.33 years each) are tied for sixth, followed by the Cincinnati Reds (27.37), Detroit Tigers (27.41) and Colorado Rockies (27.42). Most of the teams with the youngest rosters are struggling ā of the 10 clubs on this list, only the Guardians and Tigers made the postseason in 2024.
For now, Washington baseball fans and folks wagering on the team at Virginia sportsbooks can only hope that a youthful roster can put the Nationalsā recent on-field woes behind them. Weāll see if they can upend expectations when the MLB season starts in the nationās capital.
