Since the beginning of the 2017 season, Eddie has out homered Sano 89 to 79. It seemed like a fluke in 2011 when Eddie hit one more home run than Miguel, (21/20), but he did it again in 2014 and 2018, and came real close in 2017 and 2019.
They certainly take VERY different approaches to hitting: swing and miss vs contact, selective versus free-swinging, hard-hit versus less hard-hit (Rosie rarely can hit the ball over 100mph), but at the end of the day, the power production is similar.
So much the better if Eddie starts being more selective.
And how many at bats did each have in those seasons? It's a little misleading to say Rosie 'out homered' Sano without taking that into consideration.
