Trout had the most WAR before turning 22

I just happened to check his WAR on Aug. 7, his 22nd birthday. See Ranking The Best Players At Ages 20 & 21 Combined. At that point, he had a WAR of 17.3 for the ages 20 & 21 combined. He had .7 WAR in 40 games at age 19. So that gives us a total of 18.0 before turning 22. Some of guys in the table below might have played some games after they turned 22 in what is called their age 21 season (birthday on June 30 or earlier). But Trout is still ahead of them all. Notice how he did it in alot fewer games than his closes rivals.
