I think the pretty simple answer can be found in their philosophy, that Arnold has repeatedly stated this year “We’ll add bats but not at the cost of our defense.” While I agree it does make Canha a weird fit, there have been numerous reports throughout the minors that Sal’s routes to balls were poor and he can sometimes misjudge balls. Based on what I've seen with the eye test, I dont really disagree w that assessment so far at the major league level. Hes made some great plays but also feel like hes definitely left some out there that he could have made. Meanwhile, Wiemer has been one of the best CFs in the game this year, and moving him off CF to get Canha into RF and Sal in CF (at least vs RHP) kind of is a lateral move at best. Just my thoughts.
