The White Sox recalled Sandlin from Triple-A Charlotte to start Sunday's game against the Cardinals.
The right-hander has a 6.93 ERA, 1.38 WHIP and 24:12 K:BB across 24.2 innings for Chicago this season and will step onto a big-league mound Sunday for the first time since early August. It's likely just a spot start for Sandlin given that the rest of the rotation is currently in good health.
