MLB Games to Watch This Week
Two matchups featured on the August 18 evening slate offer a broad range of player markets.
Chicago White Sox at Chicago Cubs
The White Sox visit the Cubs at Wrigley Field, with first pitch scheduled for 8:05 p.m. ET on August 18. The forecast calls for sunny conditions, a temperature of 74 degrees, and a 9 mph wind from the southwest.
Kevin Gausman is the listed probable starter for the Cubs, while Bryan Hudson is listed for the White Sox. Gausman鈥檚 strikeout market varies by operator: some books list 5.5 strikeouts, while others list 6.5. That distinction is important when comparing a sportsbook market with any projection offered on Underdog.
Recent trend data shows Gausman failed to exceed 5.5 strikeouts in two of his previous three starts against the White Sox. He also failed to exceed that mark in three of his previous four home starts. Those are small samples rather than guarantees, but they provide context for evaluating his projection.
Other trends to monitor include:
- Andrew Benintendi: Recorded at least one hit in six of his previous seven road games.
- Miguel Vargas: Recorded at least one hit in four consecutive road games.
- Alex Bregman: Recorded at least one hit in six consecutive games against the White Sox.
- Pete Crow-Armstrong: Recorded at least one hit in 10 of his previous 14 games.
Los Angeles Dodgers at Colorado Rockies
The Dodgers face the Rockies at Coors Field, with first pitch scheduled for 8:40 p.m. ET on August 18. The forecast calls for partly cloudy skies, a temperature of 89 degrees, and an 11 mph wind from the east-northeast.
Eric Lauer and Ryan Feltner are the listed probable pitchers. Available market data lists both starters at 3.5 strikeouts at multiple operators. Lauer exceeded 3.5 strikeouts in two of his previous three appearances against Colorado, while Feltner failed to exceed 3.5 in five of his previous six home starts.
Coors Field often draws attention to hitter projections, but venue alone should not determine a selection. Recent player trends offer additional context:
- Andy Pages: Exceeded 1.5 total bases in four consecutive road games.
- Mookie Betts: Failed to exceed 1.5 total bases in 10 of his previous 12 road games.
- Freddie Freeman: Failed to exceed 1.5 total bases in 12 of his previous 14 games.
- Willi Castro: Recorded at least one hit in 11 of his previous 12 home games.
- Connor Norby: Recorded at least one hit in four consecutive games against the Dodgers.
Important Note About Projections and Odds
Sportsbook props and Underdog projections are not interchangeable. A sportsbook may offer an over/under with odds attached, while Underdog generally asks users to select whether a player will finish higher or lower than a posted projection. Lines can also differ across operators and change as lineups, weather, and pitching plans are confirmed.
Before submitting an entry:
- Confirm that the player is active and expected to start.
- Check the projection shown inside Underdog rather than relying on a third-party number.
- Review weather and lineup updates.
- Understand how ties, postponed games, shortened appearances, and late scratches are graded.
- Read the rules for the specific game format available in your jurisdiction.
