Christian Barnett, CF
Barnett was quite dominant as a CF for 8 years in his mid 20s to early 30s before retiring at age 37. He was drafted 4th overall by the White Sox in 1933 out of the Texas University Interscholastic League. He was MVP in 1943, won two gold gloves as well as two silver sluggers, went to the all-star game 6 times, was a World Series champ, and twice won a playoff MVP award.

Eddie Lopp, C
Lopp had a very strange career usage pattern for the catcher providing the most value over his career in Major League history: he was a backup most of the time. Yes, that's right - the lone catcher with more career WAR than Morton Zepp averaged 97 games per year over his 18 year career. His best years were by far his age 36 (4.8 WAR), 38 (5.1), and 41 (4.0) seasons. Lopp was drafted in the 3rd round of the 1927 draft out of West Babylon High School and went to 5 all-star games and won three silver sluggers.

Blake Gribler, LF
Gribler's career was split quite evenly between the Rangers and Rays with a year with the Yankees split in between. He was a college draftee from Fordham, selected 8th overall in 1934. He was Rookie of the Year in 1936 and MVP in 1937 and attended four all-star games, won five silver sluggers, and was AL Division Series MVP.

Jeremy Brook, LHP
Brook was a crafty 4-pitch left-handed pitcher with a fastball, cutter, changeup, and forkball who was also drafted out of Fordham. His career was split between the Braves, Pirates, and Athletics where he supplied 9 seasons of 3-6 WAR. He was a two-time all-star.
Career Stats: 2350 IP, 789 BB, 792 K, 3.34 FIP, 92 FIP-, 39.8 WAR, 48.4 JAWS
Louis Hayes, CF
Hayes burst on the scene in 1940 with an 8.0 WAR MVP season at age 24. For the next 5 seasons he accumulated another 23.3 WAR, giving him a career total of 31.3 going into his age 30 season. His career finished after he turned 34 with a total WAR of 39.3. He did run into some injuries - a torn abdominal muscle and a recurring herniated disc that may have contributed to his sharp decline.
Career Stats: 5928 PA, 1565 H, 49 HR, 73 SB, .338 wOBA, 113 wRC+, 73.0 ZR, 39.3 WAR, 36.7 JAWS
Jeremiah Locust, RF
Locust was the 15th overall pick out of South Carolina in 1934 and had a very steady career for the Padres, where he made six all-star games, won two silver sluggers, and was the 1947 AL Division Series MVP. His career spanned much of the time between World Series for the Padres and he retired without a championship ring.
Career Stats: 8543 PA, 2155 H, 77 HR, 127 SB, .342 wOBA, 115 wRC+, 61.2 ZR, 40.6 WAR, 35.3 JAWS
