3. Domingo Santana
The right-handed hitter is a very one-dimensional player and arguably a DH at this stage of his career.
In 2019, the 27-year-old hit .253/.329/.441 with 21 homers and 69 RBI to give himself a 107 wRC+ and 0.0 fWAR.
His fWAR was so low due to his abysmal defense in right field for the Seattle Mariners that saw him register -17 DRS and a -16.1 UZR in 865 2/3 innings split between left and right field.
If the White Sox are willing to ignore defense, though, his .820 OPS against left-handers actually would look very nice paired with Mazara in a platoon role.
As a platoon partner, Santana would not even be playing every day, which could possibly mitigate concerns about his defense killing the team regularly.
That being said, his defense is the reason he’s the third option of the three talked about in this article, especially when it’s considered that the White Sox struggled defensively in 2019.
The advantage of adding Santana is that he’s significantly younger than both Pillar (31) and Pence (36).
If he could replicate his 2017 season with Milwaukee Brewers that saw him have a 3.3 fWAR or come close to that level of production, Santana could potentially turn into a building block for the White Sox in the same sense they are hoping Mazara can.
All three of these options could certainly help the White Sox form a solid platoon situation with Nomar Mazara in 2020.
