The average age of active players across the MLB in 2023 is around 27, but as of Opening Day, there are 10 active players aged 39 or older. In fact, the league's oldest player, Rich Hill of the Pittsburgh Pirates, is still on the mound at the age of 43.
The oldest player in MLB history is Satchel Paige, who played his final MLB game for the Kansas City Athletics on Sept. 25, 1965, at 59 years of age. His ability to stay in the game until he was almost 60 was obviously out of the ordinary, but there are still a few players proving that age is just a number when it comes to a career in baseball.
*Note, all ages are as of 2023 Opening Day.
