There's a huge pitching mismatch here not reflected in the line where White Sox righty Lucas Giolito is only a slight home favorite against Cardinals lefty Steven Matz.  

The White Sox play better at home and they hit better against lefties where they have above average statistics in batting average and slugging percentage versus southpaws.

Matz is 0-7 with a 5.02 ERA. He's pitched his way out of St. Louis' starting rotation. This is Matz's first start since May 24. 

Matz has been at his worst on the road going 0-3 with a 7.14 ERA. 

Giolito is 3-2 at home with a 2.43 ERA. He has a 23-to-3 strikeout-to-walk ratio in his last three starts spanning 19 innings.
