While oftentimes switch-hitters such as Justin Smoak are not perceived to have major platoon splits, they often still do, sometimes to the same extent as hitters who only bat from one side of the plate. We can usually guess based off what arm he throws with. For example, Smoak throws with his left-hand, thus we can guess that he is a more natural left-handed hitter than a right-handed hitter, and thus may struggle against left-handed pitching.
For Smoak, the platoon splits confirm this theory. In his career, Smoak has posted just a 94 wRC+ against left-handed pitching. This is likely driven primarily by the drop in his hard-hit rate, which goes from 36.6% against right-handed pitching to 32.4% against southpaws.
Against one of the toughest left-handed pitchers on the planet in Chris Sale, there isn't any point in messing around with Smoak, even though it won't be a lefty-lefty matchup.
