This is awfully close to lying with statistics.
2017 - 2.4 WAR
2018 (71 games) - 0.1 WAR
2019 - 2.7 WAR
2020 (53 games) - 0.5 WAR
2021 - 0.0 WAR
By making your cut off "the last four, including this year" you cut off 2017 where he accrued 2.4 WAR (all WARs are from FanGraphs). Also, in 2018 he played less than half a season, and 2020 was, of course, The Covid Season where everyone played half a season. The 2020 AL leader in WAR was Jose Ramirez with "only" 3.4. Compare that to 2019, where the AL leader was Alex Bregman with 8.5. You can't hold 0.5 WAR in 53 out of 60 games against Sano.
