Dive Into the Simulation and Insights for Mariners vs Astros Match Preview - August 15, 2026

+105O/U: 8.5
(-110/-110)-125

Emerson Hancock – Over/Under 4.5 Strikeouts (-130/+100)
Emerson Hancock’s change-up rate has fallen by 15% from last season to this one (20.2% to 5.2%) .
Explain: Because change-ups are one of the most effective pitches to use, a pitcher who alters his pitch mix to use them less often may see less success as a result, particularly if he uses his fastball more instead.
Cal Raleigh – Over/Under 0.5 Hits (-135/+105)
Cal Raleigh is penciled in 8th in the lineup in today’s game, which would be a downgrade from his 81% rate of hitting in the top-half of the batting order this season.
Explain: The lower in the order a player bats, the fewer plate appearances he will get and the fewer opportunities he will get to hit the Over for every market. A player who hits lower in the order than he normally does may provide extra value opportunity since the market may be based on him hitting higher.
Seattle Mariners – 2H Moneyline
The Seattle Mariners bullpen projects as the 8th-best in MLB, via the leading projection system (THE BAT).
Explain: Most bettors only consider the starting pitcher, but a strong bullpen sneakily creates a tougher matchup for the opposing offense and suppresses a game’s runs.

Houston Astros – 1st Five Innings (F5) Moneyline (-130)
Checking in at the 78th percentile, Hayden Wesneski has notched a 3.15 K/BB rate since the start of last season.
Explain: K/BB rate is one of the best measures of a pitcher’s effectiveness in a given season, regardless of his ERA (which is prone to extreme randomness and luck).
Isaac Paredes – Over/Under 1.5 Total Bases (+150/-195)
Isaac Paredes pulls a high percentage of his flyballs (46.2% — 100th percentile) and is a great match for the park considering he’ll be hitting them towards the game’s 2nd-shallowest LF fences today.
Explain: This player’s skill set matches up particularly well with the park he’s in today, which may lead to better-than-usual performance.
