You can find this bet for -102 on Fanduel.
The premise of this bet is that we like both pitchers in this game to keep the total under the mark. The X stats have been elite for Skenes as he holds lefties to a rate of (.130/.271) and righties to a rate of (.108/.262). The X stats have been elite for Harrison as he holds RHH to the tune of (.136/.273). Lock in the under!
