The Highlights

  • The afternoon game in Detroit boasts the highest Weather Rating this season outside of Colorado and Texas.
  • Seattle’s game offers the worst weather of the evening with the total already dropping from 8.5 to 7.5.
  • Both Baltimore and St. Louis have a decent chance of rain, with Baltimore being more prone to a rainout.

Thursday brings a variety of weather to the table. We have flash-flood watches in Baltimore, terrific daytime weather in Detroit and stereotypically dreary weather in Seattle.


Using Weather Ratings from FantasyLabs and a smattering of local/national forecasts, here’s what you need to know for today’s baseball slate:

Highest Weather Ratings

  • Angels at Tigers: 84
  • Red Sox at Astros: 75*
  • Indians at Twins: 71
  • Pirates at Cardinals: 71

Subtropical Storm Alberto has moved on to Canada, leaving great baseball conditions for the matinee in Detroit. The Weather Rating of 84 is the highest of the season excluding Coors Field and Globe Life Park in Arlington. In a game featuring Andrew Heaney and Ryan Carpenter, the total opened at 9.5 and is now sitting at 10 (o-120.)  Even with that move, more than 70% of dollars coming in on the over.

You may see the asterisk I put next to the Astros game. That is because there is a fairly decent chance the janitor with the keys to the Minute Maid Park roof decides to close the joint. With hot and humid conditions between 85 and 90 degrees, I’d put my money on a closed roof.

Up in Minnesota, Cleveland’s Shane Bieber, who I assume has royal Bieber blood flowing through his veins, takes on Jake Odorizzi of the Twins.


Bieber tossed a AAA no-hitter in his last start and has earned a call up for his Major League debut. Unfortunately, he has to deal with some good hitting conditions in Minneapolis, where temps will be in the upper 70s to low 80s.

The game in St. Louis will also feature a strong environment for hitting, but also has a good chance for a rain delay. More on that in a bit.

Lowest Weather Ratings

  • Rangers at Mariners: 24
  • Rays at Athletics: 38

As is often the case, the West Coast is providing the worst Weather Ratings of the day. Leading the way is Rangers-Mariners game. Although two pedestrian pitchers in Mike Minor and Wade LeBlanc are starting, the total has gone from 8.5 to 7.5. About three quarter of early bets are on the under at Safeco, which will boast temperatures in the mid-50s.


Two games in particular have noteworthy chances of precipitation.

  • Yankees at Orioles
  • Pirates at Cardinals

There’s unfortunately been some bad flooding in the Maryland area in recent days, and more flash-flood watches and warnings are in the area tonight. Thunderstorms will be scattered throughout, making it tougher to predict if/when rain will hit Camden Yards, but any potential rain won’t be light in nature.

The Greater St. Louis area will also be experiencing some scattered thunderstorms, but the timing is a bit different. While Baltimore could see storms up until 11 p.m. ET, the weather in St. Louis is not expected to linger on through the night. There could definitely be a delay at the start of the game, but I don’t expect one once the game starts. The Baltimore game is another story, with delays and even a postponement a possibility.
