Review Athletics vs Mariners Betting Line and Odds - 9/5/2026

+205O/U: 8
(-110/-110)-245

Athletics – 1st Five Innings (F5) Moneyline (+175)
Jeffrey Springs has been unlucky this year, compiling a 6.37 ERA despite the leading projection system (THE BAT) estimating his true talent level to be 4.70 — a 1.67 deviation.
Explain: Pitchers that are underperforming should be expected to pitch better going forward, which can create value if the lines are too heavily weighing the lucky, to-date underperformance.
Donovan Walton – Over/Under 0.5 Hits (-120/-110)
Despite posting a .357 wOBA this year, the leading projection system (THE BAT X) believes Donovan Walton has had positive variance on his side given the .066 discrepancy between that mark and his estimated true talent wOBA of .291.
Explain: Players that are overperforming should be expected to play worse going forward, which can create value on prop Unders if the lines are too heavily weighing the lucky, to-date overperformance.
Lawrence Butler – Over/Under 0.5 Total Bases (-170/+130)
Lawrence Butler has a 97th percentile opposite-field rate on his flyballs (37.4%) and has the good fortune of hitting them towards MLB’s 9th-shallowest LF fences in today’s matchup.
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.

Seattle Mariners – Moneyline (-245)
The Seattle Mariners infield defense grades out as the worst among all the teams in action today.
Explain: Defense is an integral part of preventing (or, in this case, allowing) hits and runs.
J.P. Crawford – Over/Under 0.5 Hits (-140/+110)
J.P. Crawford is projected to bat 9th on the lineup card in today’s game, which would be a downgrade from his 63% rate of hitting in the top-half of the batting order this year.
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.
The Seattle Mariners have been the unluckiest offense in the majors this year, according to the leading projection system (THE BAT X), and are likely to hit better in future games
Explain: When teams underperform their projected talent level, markets may undervalue them even while they are likely to perform better in the near future.
