Angels Are Just Playing Out The String
The Angels have dropped the first two games of this series, including a 2–1 loss last night where Logan Davidson’s RBI double briefly tied the game before Mitch Garver answered with a solo shot. Los Angeles managed just four hits and went 0-for-5 with runners in scoring position, continuing a cold stretch where they’ve averaged 2.6 runs over their last seven games. Tonight, they turn to rookie left-hander Mitch Farris (1–0, 2.45 ERA), who’s impressed in his first two MLB starts—allowing just three earned runs over 11 innings with a 0.82 WHIP.
Farris brings a deceptive fastball and a sharp curveball that’s generated soft contact early in counts. He tossed six strong innings against the Athletics in his last outing, allowing just three hits and striking out four. Against a Mariners lineup that’s aggressive early and ranks top-five in home runs, Farris will need to stay ahead in counts and avoid middle-third misses. Offensively, the Angels remain reliant on Mike Trout and Zach Neto, but the supporting cast has struggled to produce. If Bryce Teodosio and Logan O’Hoppe can extend innings, Los Angeles has a chance to flip the script.
Defensively, the Angels have been clean, committing just one error in their last five games. Kenley Jansen remains reliable in save situations, and the middle infield tandem of Neto and Luis Rengifo has turned key double plays. The challenge tonight will be containing Julio Rodríguez and Jorge Polanco, who’ve combined for 96 extra-base hits this season. If Farris can navigate the top of the order and keep traffic off the bases, the Angels have a path to avoid the sweep.

Mariners Are Tied Atop The AL West
Seattle enters tonight riding a six-game win streak, including taking the first two games of this series after last night’s 2–1 victory. Jorge Polanco opened the scoring with a two-out RBI double, and Mitch Garver’s go-ahead homer in the seventh sealed it. The bullpen was lights-out again, with Andrés Muñoz locking down his 35th save and Carlos Vargas earning the win. With the win, the Mariners have now pulled even with Houston atop the AL West, setting up a high-stakes final stretch. Bryan Woo (13–7, 3.02 ERA) gets the nod tonight, looking to extend Seattle’s momentum and complete the sweep.
Woo has been one of the most consistent arms in the rotation, posting a 0.95 WHIP and holding opponents to a .205 average across 175 innings. He’s especially sharp at home, where his ERA dips and his strikeout rate climbs. Offensively, Seattle is clicking—Julio Rodríguez has five homers and 17 RBIs in his last ten games, while Polanco has doubled in five straight, tied for the longest active streak in the majors. Against Mitch Farris, expect the Mariners to test the rookie early with aggressive swings and pressure on the basepaths.
Defensively, Seattle has been airtight. Victor Robles robbed a potential two-run double in the sixth last night, and the infield—anchored by Polanco and J.P. Crawford—continues to turn momentum-shifting plays. With Woo on the mound and the bullpen rested, Seattle has the edge in both pitching depth and late-game execution. If they grab an early lead, they’re well-positioned to close out the series with a sweep and keep pace in the AL West race.

Los Angeles Angels vs Seattle Mariners Pick
Angels vs Mariners Spread Pick
Seattle -1.5 is a sharp play in a matchup where they hold clear advantages in pitching, momentum, and situational leverage. Bryan Woo enters with a 3.02 ERA, a sub-.210 opponent batting average, and 20 quality starts on the year—he’s averaging over six innings per outing and has allowed two or fewer earned runs in five of his last six appearances. The Mariners have won six straight and are now tied with Houston atop the AL West, giving them full urgency to close out the sweep. Against rookie Mitch Farris, who’s making just his third career start, Seattle’s aggressive top half—led by Julio Rodríguez, Cal Raleigh, and Jorge Polanco—should generate early damage and flip the game script.
Seattle has also covered the -1.5 run line in four of its last five wins, and they’re 7–2 when favored at -220 or shorter. The bullpen has been lights-out, with Andrés Muñoz locking down his 35th save and Carlos Vargas emerging as a reliable bridge arm. Defensively, the Mariners have been airtight, and their ability to control tempo late gives them a strong edge in closing out multi-run leads. With Woo’s consistency, the lineup’s power surge, and playoff stakes in full view, Seattle is well-positioned to win by margin and keep pace in the division race.

Angels vs Mariners Over/Under Pick
Under 7.5 sets up well in a matchup featuring two capable starters and two lineups that have struggled to string together runs. Bryan Woo enters with a 3.02 ERA and 20 quality starts, while rookie Mitch Farris has allowed just six hits across his first 11 MLB innings. Seattle’s bullpen has been dominant during its six-game win streak, and the Angels have scored two runs or fewer in four of their last six contests. With both teams trending toward low-scoring outcomes and playoff pressure tightening pitch selection, this profiles as a 4–2 type game that stays comfortably under the number.
