If I had to pick the worst starting pitcher during the second half of the season the name Dylan Covey would emerge. Covery is 0-4 with a 14.26 ERA in eight second-half appearances. Covey hasn't been very good all season. He's 1-7 with an 8.14 ERA. 
I'm surprised Covey is getting another start having those dreadful numbers. But as long as he's going back to the mound, I'll find a way to fade him and that's by going above this total. 
I can't trust Seattle starter, southpaw Yusei Kikuchi, at this big of a lay price. So going above the total is the safest way. It's easy to envision these teams combining to reach double-digit runs. 
The White Sox are averaging 5.6 runs in their last nine games. The Over is 11-3-2 during their last 16 away games. 
Kikuchi has a 5.24 ERA on the year. The White Sox have the third-highest batting average in the American League against lefties. The Over is 19-8-1 in Kikuchi's last 28 starts.
