Seattle Mariners

Athletics
(+100/-120)-105
On May 5, 2025, the Oakland Athletics will host the Seattle Mariners at Sutter Health Park in what promises to be an intriguing American League West matchup. The Mariners are coming off a rough outing, having lost their previous game 8-1, while the Athletics are riding high after a narrow 3-2 victory. Both teams are vying for a strong start in this three-game series, which adds to the intensity of the matchup.
The Athletics currently sit at 19-16, showcasing an above-average season, while the Mariners boast a 20-13 record, indicating they are having a great year. Oakland’s offense ranks 10th in MLB, particularly excelling in power with the 6th most home runs, though they struggle with speed on the bases, ranking dead last in stolen bases. Conversely, Seattle’s offense ranks 4th overall, also demonstrating significant power with the same 4th rank in home runs, and they sit 5th in stolen bases, highlighting their ability to create scoring opportunities.
On the mound, the Athletics are projected to start Luis Severino, who has had a mixed season with a 1-3 record and a solid 3.30 ERA. Despite his low win total, advanced metrics suggest he has been somewhat fortunate, as his 3.98 xFIP indicates potential for regression. Severino’s recent form shows promise, particularly after a strong outing where he allowed just one earned run in five innings.
Bryce Miller, set to take the mound for the Mariners, has had a solid season as well, with a 2-3 record and a respectable 3.52 ERA. However, like Severino, his 4.43 xFIP points to some potential struggles ahead.
With the Athletics’ offense projected to score 4.39 runs and the Mariners at 4.61, this game could be a high-scoring affair, especially given the Game Total is set at 9.0 runs. Betting markets indicate a close contest, with the Mariners slightly favored at -120. As both teams look to gain momentum, the matchup between Severino and Miller could be pivotal in determining the outcome.
Seattle Mariners Insights
- Bryce Miller – Over/Under 4.5 Strikeouts (-125/-105)Bryce Miller’s 93.8-mph velocity on his fastball this year is a substantial 1.3-mph drop off from last season’s 95.1-mph mark.Explain: Velocity is a key component to fastball success in generating strikeouts and preventing runs, so a pitcher whose velocity decreases will likely see worse results.
- Cal Raleigh – Over/Under 1.5 Total Bases (+100/-130)Cal Raleigh is an extreme flyball batter and faces the weak outfield defense of Sacramento (#1-worst of the day).Explain: This player’s skill set matches up well with the opposing team’s defensive weakness, which may lead to better-than-usual performance.
- Seattle Mariners – 2H MoneylineThe Seattle Mariners bullpen grades out as the 8th-worst in Major League Baseball, per the leading projection system (THE BAT).Explain: Most bettors only consider the starting pitcher, but a weak bullpen sneakily creates an easier matchup for the opposing offense and boosts a game’s runs.
Athletics Insights
- Athletics – 1st Five Innings (F5) Moneyline (-115)Luis Severino is an extreme groundball pitcher (43.4% GB% per the leading projection system, THE BAT), which should make him somewhat immune to the dangers of pitching in Sutter Health Park — the #7 HR venue among all major league stadiums — in this game.Explain: This pitcher’s skill set matches up particularly well with the park he’s in today, which may lead to better-than-expected performance.
- JJ Bleday – Over/Under 0.5 Hits (-170/+130)JJ Bleday has primarily hit in the top-half of the batting order this year (85% of the time), but he is projected to bat 6th in the batting order today.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.
- Brent Rooker – Over/Under 1.5 Total Bases (+125/-160)Brent Rooker hits a high percentage of his flyballs to center field (39.9% — 97th percentile) but may find it hard to clear MLB’s 11th-deepest CF fences today.Explain: This player’s skill set does not match up particularly well with the park he’s in today, which may lead to worse-than-usual performance.
