Mariners vs Athletics MLB Betting Preview
The Mariners and Athletics just completed a four-game series last weekend and face off again this weekend in Sacramento. Despite Seattle's home park favoring pitchers, these two teams combined for over 10 runs in two of the four games.
Although they went under, with eight total runs, in the last start between Jeffrey Springs and George Kirby, they should hit the over today.
The Athletics' park is the league's most hitter-friendly stadium, with a 112 park factor in 2026. Also, Jeffrey Springs is much worse while pitching there than on the road.
Meanwhile, George Kirby is a much worse pitcher on the road.
- Kirby away: 5.48 ERA, .389 wOBA allowed, 1.63 WHIP, 4.33 FIP, 4.21 xFIP
Mariners vs Athletics Pick, Betting Analysis
Both the Mariners (105 wRC+) and Athletics (103 wRC+) are above-average offenses in the past 30 days. Also, given that both teams have faced today's opposing pitchers within the past week, hitters have an extra advantage.
The Mariners have a largely available bullpen, but their star closer Andres Munoz has thrown 41 pitches in the past two games, with three outings in the past five games.
He is likely unavailable today, giving the over an added chance of success.
Pick: Over 10 (-105, BetMGM)
