The Seattle Mariners and Detroit Tigers kick off Friday night at Comerica Park at 6:40 PM ET, and this game is set up perfectly for a same-game parlay. Bryan Woo is absolutely on fire right now — the Mariners right-hander has been one of the most dominant pitchers in the American League over the last month — and he's drawing the Tigers, who have been one of the more strikeout-prone lineups in the game. The Mariners come in as -136 favorites with a total of just 8 runs.
This SGP is built around one simple truth: when Bryan Woo is dealing, the Mariners win low-scoring games. And right now, Woo is dealing as hard as anyone in baseball. Parlay that with the matchup data pointing to Detroit getting shut down, and this three-legger writes itself.
Bryan Woo Over 5.5 Strikeouts: The No-Brainer Leg
Let's talk about what Bryan Woo has been doing lately, because it's borderline absurd. Over his last three starts, he went for nine, eight, and nine strikeouts. In his last seven starts combined, he's racked up 53 strikeouts in 40.2 innings — that's 11.73 strikeouts per nine innings during that stretch. He's the hottest strikeout arm in the American League right now, and tonight he gets the Detroit Tigers.
The Tigers have been a rough offense in 2026, and their strikeout rate against opposing pitchers ranks among the higher marks in the AL. This is the kind of matchup that oddsindex.com flagged as an "OVERHIGH" play today, projecting Woo for 7.2 strikeouts in this spot. The line is 5.5 at -115 — manageable juice on a near-lock. If Woo is anywhere close to the form he's shown over the past month, he's clearing 5.5 strikeouts before the seventh inning ends. This is the foundation of the entire parlay, and it's a foundation built on granite.

Woo's total numbers on the season: 5-3 record, 3.44 ERA, and 68 strikeouts in his starts. Seattle is -136 tonight for very good reason — they have one of the game's best pitchers in peak form.
Seattle Mariners -1.5: Bet the Woo Runline
Here's where the SGP gets fun. If you believe Bryan Woo is going to dominate — and the data says you should — then you should also believe the Mariners are going to win by multiple runs. When Woo has his stuff working, Seattle doesn't just win; they win comfortably. Look at his last few starts: the White Sox were shut out while Woo threw six innings and struck out eight. The Astros got two runs off him in six innings while Seattle won 10-2.
The -1.5 run line for Seattle adds meaningful extra juice to the parlay while staying firmly within the correlated story. A dominant Woo outing almost certainly produces a run differential of two or more. Framber Valdez is on the other side for Detroit — a 2-4 record with a 4.39 ERA — and while Valdez can be streaky, the Tigers offense behind him isn't generating enough runs to keep this game close when Woo is in lockdown mode. The -1.5 run line for the Mariners prices somewhere around -140 to -160 depending on your book. It's juice, but it's juice that makes sense within the correlated structure of this parlay.
Game Total Under 8: The Woo Effect Finishes It
The third leg is the under on the game total of 8. With Woo projecting for 7.2 strikeouts and the Mariners' defense behind him, Detroit scoring more than four runs in this game would be a genuine upset. And Framber Valdez, despite his mediocre 2026 numbers, is still a veteran arm who can limit damage against Seattle's lineup on a given night. The combination of Woo capping Detroit and Valdez putting up a competitive start from his side means a total of 8 has significant under pressure.
The under on this game is the cleanest of the three legs in isolation, and it becomes even cleaner when you stack it with the Woo strikeout over and the Mariners -1.5. All three legs require Woo to dominate — and if he does, all three cash. That's the beauty of a well-constructed SGP. The MLB betting guide at Eat Watch Bet has a great primer on how to think about SGP construction if you want to go deeper on the strategy side.
