In his seven full seasons, Mike Trout has averaged 9.1 WAR, with a low of 6.7 — when an injury limited him to 114 games in 2017 — and a high of 10.5 in both ’12 and ’16. He also posted 10.2 last season, despite a stint on the disabled list. Given that, it’s not unreasonable to think a healthy Trout could accrue up to another 11 WAR.
