Perhaps what Rosario is best known for is the fact he’s an all or nothing hitter. While the left-handed power bat is a threat to go deep every time he’s at the plate, he also strikes out at a high rate and struggles to work walks.
From 2017-2019, Rosario hit at least 24 home runs, including a single-season career-high 32 in 2019. However, that season his on-base percentage was just .300 and his career-high OBP is only .328.
In his career, Rosario has never worked more than the 35 walks he drew in 2017. In comparison, longtime Indian Carlos Santana, who Rosario will replace in the power department in 2021 with Santana in Kansas City’s career-low for walks in a full season, was 88 (2017).
Thus, Rosario’s power will clearly help an Indians team that struggled to drive the ball out of the yard last season, but he will not help at all in replacing the remarkable plate-discipline provided by Santana nine of the last ten years.
