Mariners Preview: Can Seattle Bounce Back After the Walton Walk-off?

Seattle Mariners · 2026-09-12 · Beatline Sports Podcast Network

Nicole: Donovan Walton just lit up the night with a tenth-inning walk-off two-run homer, and now we’re staring down Game Two of this series against Oakland. If you missed that heartbreak, or if you’re already bracing for more pain, you need to listen right now.

Kevin: It’s a tough pill to swallow after the dominance we saw from Jacob deGrom just days ago. But in baseball, you reset. We are back at the Beatline Podcast Network, and I’m Kevin.

Nicole: And I’m Nicole! Welcome, Mariners fans, to your daily preview. Today, we break down how Seattle responds to that late-night loss, who might take the mound tonight, and whether the bullpen can survive another long game.

Kevin: We’ve got three things coming up. First, we look at the pitching matchup and what it means for the rotation. Second, we dive into the lineup changes and those lingering injury reports from both sides. And third, we give you our keys to victory for tonight’s contest.

Nicole: Let’s get right into it. The Mariners dropped last night, 6-5, thanks to that Donovan Walton blast. It’s a bitter taste, but we move on. Let’s talk about tonight.

Nicole: So, Kevin, last night was a grind. Ten innings. Who do you see starting tonight for Seattle? Do they go back to the pen, or is there a starter available?

Kevin: Well, looking at the roster, we have Logan Gilbert, George Kirby, Bryce Miller, Kade Anderson, and Bryan Woo. Given the fatigue from last night, I wouldn’t be surprised if they try to squeeze one more start out of the rotation to keep the pen fresh for the rest of the week.

Nicole: Right. And remember, just a few days ago, we were talking about Jacob deGrom retiring his first fifteen batters. That kind of performance makes the rest of the staff look even more critical. If deGrom isn't starting, who takes the ball?

Kevin: I think Bryce Miller is a strong candidate here. He’s been solid, and he gives them quality innings. But if they want to protect him for a potential playoff push, maybe Kade Anderson gets the nod. He had that recent rookie win we mentioned yesterday.

Nicole: That’s a good point. Anderson has momentum. But let’s be real, the Athletics aren’t exactly a powerhouse. They’re 59-88, fourth in the AL West. Seattle is 69-79, third in the AL West. This is a must-win for Seattle to maintain any semblance of separation.

Kevin: Exactly. It’s not just about winning; it’s about controlling the narrative. If Seattle loses this series sweep, they’re falling further behind. The ABS challenge system tracker shows how tight things are with umpires and teams alike. Every pitch matters.

Nicole: So, if it’s Miller or Anderson, the key is early contact. You can’t afford to go deep into games again. Last night’s extra inning was brutal on the arms.

Kevin: Agreed. You need to get through five, six innings minimum. That’s where the bullpen comes in. And that brings us to our next segment: the bats and the bullpens.

Nicole: Okay, let’s talk offense. Julio Rodríguez hit that huge three-run homer off Jakob Junis in the seventh against Texas. He’s clearly in a groove. How do you want to see him approach the A’s tonight?

Kevin: Julio is the engine. Whether it’s against deGrom or Junis, he’s creating value. Against Oakland, I’d love to see him leverage his plate discipline. The A’s bullpen can be vulnerable to high-OBP threats if they chase strikes.

Nicole: And don’t forget Cal Raleigh. We predicted he’d hit a homer against the Rangers, and while the team lost, he showed power. Does he have an advantage against Oakland’s defense?

Kevin: Raleigh is always a threat. But we also have to consider the injuries. Shea Langeliers is on the 10-Day IL for Oakland. That weakens their catching depth significantly. If Seattle targets the backup catcher, they might find some platoon splits to exploit.

Nicole: Good catch, Kevin. It’s all about the matchups. What about the rest of the lineup? Randy Arozarena and Victor Robles are out there too. Are they getting enough support?

Kevin: They need to. J.P. Crawford and Cole Young are holding down the infield. If the top of the order can get on base, Arozarena can create havoc with his speed. But if the middle relief guys shut down the zone, it gets sticky.

Nicole: Speaking of middle relief, the Mariners’ bullpen has guys like Andres Munoz, Michael Rucker, and Hoby Milner. With the shortening of the season, are they saving everyone for October?

Kevin: They have to be. But you can’t save everyone every day. If Seattle goes to ten innings again, someone is going to burn. I’d expect Seranthony Dominguez or Eduard Bazardo to eat up some innings if the starter doesn’t finish.

Nicole: And we know the A’s have injuries too. Brooks Kriske, Will Wilson, Brennen Davis—all on the 60-Day IL. Their lineup is thin. That should help Seattle’s starters, right?

Kevin: It does. Fewer quality bats means fewer run-scoring opportunities. But it also means one bad swing can change everything. You have to stay disciplined.

Nicole: Let’s transition to our final segment. Keys to the series. We’ve talked pitching, we’ve talked hitting. What’s the one thing Seattle needs to do to win tonight?

Kevin: Execution in the sixth and seventh innings. That’s where games are won and lost. Last night, Seattle scored four in the seventh to take the lead, but then couldn’t hold it. They need to close out the game faster.

Nicole: Right. No more waiting for the tenth inning. If the starter goes six, the closer needs to come in and finish it. Andres Munoz is the guy for that. He’s reliable.

Kevin: But also, defensive positioning. The A’s are a low-scoring team. Don’t leave gaps open. Use the shift if needed. Keep the launch angle low.

Nicole: I agree. And offensively, capitalize on the mistakes. If the A’s pitcher walks the first batter, make him pay. One out left to work with.

Kevin: Exactly. Plate discipline is key. Don’t chase the slider in the dirt.

Nicole: Alright, bold prediction time. Yesterday, Kevin, you predicted a 2-1 series victory for the Mariners. Now, after last night’s loss, are you sticking with that?

Kevin: I am. The talent gap is still there. The Mariners have better starters, better hitters. Oakland is struggling. I think Seattle wins tonight, and maybe even sweeps the series.

Nicole: I’m going to go with a win tonight, but I’m worried about the bullpen. I predict a 5-3 Mariners win, powered by a Julio Rodríguez home run.

Kevin: I’ll take that. Julio is due. He’s been dominant.

Nicole: There you have it. From the deGrom dominance to the Walton walk-off, we’ve covered it all. Seattle needs to bounce back tonight. Make sure you tune in tomorrow for the recap.
