Seattle Mariners counter with Bryan Woo, and his 2026 trajectory is a clear regression signal. Woo went 9-3 with a 2.89 ERA in 2024 and 15-7 with a 3.02 ERA in 2025. This season, that ERA sits at 4.56. His last two outings removed any doubt: 5.0 IP, 5 ER against Texas, then 5.0 IP, 5 ER against Los Angeles. Ten earned runs in ten innings. Woo still generated strikeouts in those starts (8 Ks against the Dodgers, 5 against Texas), which tells you the stuff is there but the command and sequencing are breaking down. He already faced Detroit this season on June 5 and surrendered 5 ER in 6.1 innings. Tonight's MLB matchup drops him right back into the same fire.

Detroit arrives carrying real momentum. The Tigers are 20-10 over their last 30 games with a +71 run differential on the season, numbers that reflect genuine quality rather than schedule luck. Game 1 of this series ended 8-0, extending their winning streak to four. The statistical anchor of the DET-SEA matchup angle is Gleyber Torres, who carries a career .545 average and 1.181 OPS against Woo in 11 plate appearances across three separate seasons: 0.666 OPS in 2023 (3 PA), 1.400 OPS in 2024 (5 PA), and 1.334 OPS in 2026 (3 PA). That consistency across three years and multiple contexts makes this signal, not noise. Torres also carries a .915 OPS over his last seven days. Around him, Colt Keith is posting a 1.401 OPS over his last seven days, and Dillon Dingler has a .929 OPS over the last 28 games. Detroit's lineup is built for a moment like this.

Seattle's home record of 32-25 is decent, but the broader offensive picture is a liability. The Mariners average 4.0 runs per game on a .230 team average. Cal Raleigh, their primary power source behind the plate, is batting .163 with a .605 OPS against right-handed pitching. Raley is out with an elbow injury, trimming outfield depth. Trade-deadline addition Taylor Ward brings genuine plate discipline (.383 OBP, 87 walks on the season), but the lineup still lacks the middle-order punch to feel threatening against a live bullpen. T-Mobile Park's pitcher-friendly environment, runs factor of 0.95 and home run factor of 0.90 under the retractable roof, provides Seattle some structural cover, but Woo's recent form suggests park suppression alone will not be enough to keep Detroit quiet in Game 2.

• Detroit is 20-10 over the last 30 games with a +71 run differential for the season. Their 8-0 win in Game 1 of this series extends a four-game winning streak. This is not a team in a hot patch. It is a team that has built a sustained edge.
• Bryan Woo has allowed 10 earned runs in his last 10 innings, with consecutive 5-ER, 5-inning outings against Texas and Los Angeles. His 2026 ERA of 4.56 is a steep climb from his sub-3.00 marks in 2024 and 2025, and he has already been tagged by Detroit this season (5 ER in 6.1 IP on June 5).
• Drew Anderson is an opener, not a traditional starter. His last three outings covered 1.1, 1.2, and 1.1 innings. Detroit's bullpen, which posts a 3.53 ERA, will carry the bulk of innings. Evaluating this as a conventional starting-pitcher matchup leads to the wrong conclusions on most props and totals.
• Gleyber Torres owns Bryan Woo with a career 1.181 OPS across 11 plate appearances in three separate seasons. The production is consistent year over year, which makes this BvP edge unusually reliable compared to most small-sample career matchup data.
• T-Mobile Park plays pitcher-friendly with a 0.95 runs factor and a 0.90 home run factor, and the retractable roof eliminates weather variables. This environment suppresses run scoring for both sides, which supports the Under and helps Detroit backers on the run line more than it helps Seattle mount a high-scoring comeback.
• Seattle is 4-6 over their last 10 games and 13-17 over the last 30. Cal Raleigh is batting .163 with a .605 OPS against right-handed pitching. Raley is out with an elbow injury. The Mariners' offensive ceiling in this game is limited.

The best single angle is the Tigers ML at +132. Stack Torres Over 0.5 hits on top of it for the cleanest prop play available. The Woo Under 5.5 strikeouts at +108 adds a positive-money kicker that fits the same narrative: a pitcher being pulled early does not put up big strikeout numbers, and Woo has exited twice in a row at or before 5 innings. T-Mobile's pitcher-friendly environment creates tension between Woo's leaky form and the park's suppression effect, but the directional lean is Detroit winning in a game that stays tamped down under 8 total runs. The park suppresses both offenses, which actually helps Detroit as a run-line underdog more than it helps Seattle manufacture the runs needed to win comfortably.

One caveat worth acknowledging: Detroit's opener-plus-bulk approach introduces variance in the middle innings. A bulk arm getting tagged, or Seattle's offense finding a groove against lesser-known relievers, could flip this game late. The Mariners are 32-25 at home this season. Bet this with appropriate sizing, not max stakes, and treat the LOW-confidence plays (Under 8.0, NRFI, Torkelson under, Greene HR) as small speculative adds rather than primary exposure. No outcome in baseball is guaranteed, and responsible unit sizing is always the right framework. For the full slate, see our MLB picks today, NRFI picks, and player props.
