White Sox vs Mariners MLB Betting Preview, Pick
The Mariners are going to be using Bryce Miller as an opener and Luis Castillo in long relief, and both are great matchups for lefties at this point.
Castillo has been absolutely crushed by lefty power this season (1.93 HR/9) and grades out as a matchup that is well above average for lefty power.
This ballpark is a downgrade for Montgomery, but he has been one of the best HR hitters in the league since he came.
I have the true odds here around +300, making this a great bet.
Pick: Colson Montgomery 1+ Home Runs (+350)
