Schmidt led the league in home runs in 1984 (34 years old) and in 1986 when he won the MVP.
Chipper Jones

He also hit .321, while having an on-base percentage of .422 and an OPS+ of 153.
Jones’ WAR was 5.2 and he was an average defensive player, with a 0.0 Defensive WAR.
George Brett
A two-time All-Star in the early ’90s, George Brett had a batting average of .303 and an OPS+ of 140 from age 34 to 37.
Brett was never much of a power hitter, so his 18 home run average is not alarming. He still drove in an average of 87 runs a season.
The one area where Brett struggled was on defense, where had a defensive WAR of -0.9. But to be fair, he was never a great defender.
Adrian Beltre
The most recent player on this list is Adrian Beltre, who tied with Schmidt for the highest WAR during the span with 6.1.
Beltre averaged 25 home runs, with 89 RBI and a 130 OPS+. He slashed .307/.363/.494, while playing decent defense (1.3 defensive WAR).
Beltre is the only player on this page to win a Gold Glove (2016, when he was 37 years old). He also won a Silver Slugger in 2014.
