Top 10 Oldest MLB Rosters For 2025 Season

Fact Checked by Jim Tomlin

After a run of meteoric regular-season conquests and bitter playoff disappointments in the past couple of years, the Baltimore Orioles will try to achieve more in October, which would reward Maryland sports betting backers in 2025. The Orioles have an eye toward bringing home the first World Series title to the Charm City since 1983.

BetMaryland.com was curious which teams have the oldest rosters in MLB heading into Friday's Opening Day. Using the 26-man rosters on FanGraphs.com, listed as of March 26 (the day before Opening Day), we calculated the average age for each team and ranked the top 10 oldest teams.

In the past two seasons, Baltimore has gone from American League East laughingstock to juggernaut, winning 192 games and finishing atop the division in 2023 before placing three games behind the New York Yankees in 2024. But the Orioles’ magic has run dry in the playoffs.
