Tanner McGrath’s Mariners vs Orioles Preview
The wind is projected to be blowing in toward home plate at Camden Yards on Thursday, activating one of our more well-known Action Labs Systems: Wind Blowing In.
When the wind is blowing in at specific stadiums known for wind sensitivity (e.g., Wrigley Field, Fenway Park, Oriole Park, etc.), scoring tends to be suppressed due to reduced ball carry.
Betting the Under in these conditions — regardless of whether it's the regular season or postseason — has shown consistent profitability both in the short and long term.
This system has a 16-9-1 record this year, a 64% hit rate that has produced a 20% ROI.
Pick: Under 9.5
