Nolan Arenado, a 35-year-old third baseman for the Arizona Diamondbacks, is among a small group of players in their mid-to-late 30s who are still having success in the league. Despite struggling with a minor back issue, Arenado is continuing a bounce-back season, batting .256 with eight homers and 30 RBIs through Monday’s games.

Analytics and Velocity

The use of analytics in baseball has led to a shift towards younger players, with teams locking up young players to long-term contracts. The increased velocity of pitchers has also made it more difficult for older hitters to succeed. The average MLB fastball in 2026 is over 94 mph, with 18 qualified pitchers averaging at least 96 mph.

Arenado said that one of the first things that becomes tougher for MLB veterans is the ability to handle really good fastballs, particularly inside. He has had to adjust his work habits and mindset to continue having success in the league.

Flexibility and Maintenance

Dodgers manager Dave Roberts said that the process of aging is different for every player. Some need to work out more, while others need more sleep or a better diet. The habits that brought a player to the big leagues may not be the same ones that will keep them there in their mid-to-late 30s.

Christian Walker, a 35-year-old first baseman for the Houston Astros, said that he has embraced getting older and enjoys analyzing his blood tests to see what’s causing vitamin deficiencies or inflammation. He has also had to adjust his approach to the game, focusing on maintenance and flexibility to stay healthy and productive.
