Nicole: You are listening to the Beatline Podcast Network, your daily destination for everything baseball. I’m Nicole, and alongside me is Kevin.
Kevin: And I’m Kevin. We’re live from the network desk.
Nicole: Here’s the hook: The Mariners just avoided a sweep against the Angels with a gritty 7-2 win, but now they head to Denver to face the Rockies in a series that could define their late-season identity. With an injury list that looks like a phone book, can this team survive another round of attrition?
Kevin: It’s a tall order. We’ve talked all week about how thin the roster is, especially after yesterday’s win where Cal Raleigh and Josh Naylor carried the load. Today, we’re breaking down the pitching matchup, the bullpen fatigue, and whether Julio Rodriguez can keep his MVP case alive on the road.
Nicole: Coming up: First, we look at who starts for Seattle in Game One against Colorado. Second, we dive into the offensive lineup questions with so many guys on IL. And finally, we give you our bold prediction for the series outcome. Let’s get into it.
Nicole: Alright, Kevin, let’s start with the big picture. The Mariners are sitting at 71-82, third in the AL West. They just beat the Angels 7-2 on Wednesday night, avoiding the sweep. But now, they’re flying west to Colorado for a three-game set starting tomorrow, September 19th. Who do you have starting for Seattle tonight?
Kevin: Well, looking at the rotation options available, Logan Gilbert seems like the logical choice here. He’s been one of the few consistent anchors for them. With Bryce Miller having pitched recently and George Kirby likely needing rest or being unavailable due to the rotation cycle, Gilbert is the ace of the remaining group. He needs to go deep into this game because the bullpen is going to be taxed.
Nicole: Right, and the Rockies are coming off a series where they were trying to climb out of the cellar. Their offense isn’t exactly terrifying, but Coors Field changes everything. If Gilbert doesn’t get those six innings, we’re in trouble.
Kevin: Exactly. Coors Field inflates ERAs by about half a run across the board. So even if Gilbert has a decent game, say five or six strong innings, the margin for error is razor-thin. The key here is pitch count management. If he goes over 95 pitches early, the Mariners are handing the ball to a reliever who might not have had enough rest.
Nicole: Speaking of the bullpen, remember back on September 15th when we talked about Reid Detmers and how the Mariners needed strong pitching to counter him? Well, now they need strong pitching to counter their own depth issues. Who else is in the mix besides Gilbert?
Kevin: Bryce Miller is the other starter, but he’s likely already thrown or is on short rest. Hoby Milner is listed as a reliever but has started games before if absolutely necessary. However, the real story here is the relief corps. You’ve got Andres Munoz closing, but also Eduard Bazardo, Cooper Criswell, Seranthony Dominguez, Jose Ferrer, Michael Rucker, Gabe Speier, and Carlos Vargas. That’s nine arms. It’s a lot of names, but none of them are fresh.
Nicole: That is a crowded bus. And we haven’t even gotten to the injuries yet. On Monday, Ryan Johnson pitched well for the Angels, and Josh Lowe hit a homer to seal a 2-1 loss for Seattle. They’ve been on a losing streak leading into this. How does the pitching staff handle the pressure of potentially clinching a losing season if they drop these next three games?
Kevin: The psychological aspect is huge. When you’re fighting off the label of a 'losing season,' every inning feels heavier. The pitchers are feeling that weight. My concern is platoon splits. The Rockies will try to exploit left-handed starters. If Gilbert is on the mound, he’s right-handed, which helps against their middle-of-order bats, but if they send out a lefty-heavy lineup, the Mariners’ bullpen might have to work harder than expected.
Nicole: So, the takeaway for Segment One: Logan Gilbert gets the nod, he needs to eat innings, and the bullpen is on a knife-edge. If they get through six clean innings, they have a chance. If not, it’s going to be a long night in Denver. Stick with us, because things get even more complicated when we talk about who is actually playing.
Nicole: Welcome back. In Segment Two, we are diving into the lineup. Kevin, you mentioned the injury list earlier. Let’s look at it. We have Nolan Schanuel on the 10-Day IL, George Klassen on the 15-Day, Samy Natera Jr. on the 15-Day, Yoan Moncada on the 60-Day, Gustavo Campero on the 10-Day, Brendan Donovan on the 7-Day IL, Brennen Davis on the 60-Day, Cole Wilcox on the 15-Day, Will Wilson on the 60-Day, and Emerson Hancock on the 15-Day.
Kevin: That is... extensive. It’s essentially half the roster. When we previewed the Angels series, we focused heavily on how much the offense relied on Julio Rodriguez and Josh Naylor. Now, with Moncada, Schanuel, and others out, that reliance becomes absolute. There is no room for error.
Nicole: And yet, in that last win against the Angels, Cal Raleigh had two hits and three RBI, and Josh Naylor had two hits and two RBI. They stepped up. Do you think that performance gives you confidence that the core guys can carry this lineup again against Colorado?
Kevin: I do, but with caveats. Cal Raleigh is having a fantastic season. His ability to frame pitches and drive in runs from behind the plate is elite. Josh Naylor provides the power balance. But the guys around them—Taylor Ward, Dominic Canzone—they need to contribute. If the top three aren’t getting on base, the lower order has nowhere to go.
Nicole: Let’s talk about Julio Rodriguez specifically. On September 16th, we predicted he would get two hits against the Angels. Did he deliver? And more importantly, can he do it again in Denver?
Kevin: He did deliver. And he will likely deliver again. Julio is one of the most dynamic players in baseball. At Coors Field, his speed becomes an even bigger weapon. Stealing bases, taking extra bases on hits—it’s a hitter’s paradise for him. If he’s healthy and swinging, he’s a constant threat to change the game's momentum with a single play.
Nicole: What about the defensive shifts? With so many infielders out, like Will Wilson and Brock Rodden, how does the defense hold up? Are they going to be vulnerable to ground balls?
Kevin: That’s a valid concern. J.P. Crawford and Michael Arroyo are solid, but if they’re playing out of position or covering more ground than usual, errors can happen. The Mariners’ defense has been good overall, but consistency is hard when you’re shuffling pieces. I expect them to play conservative defense, maybe pulling the first baseman in more often, which opens up gaps for line drives.
Nicole: So, the strategy is survival. Keep the ball on the ground, rely on the outfielders—Randy Arozarena, Victor Robles, Lazaro Montes—to make plays. It’s not pretty, but it’s necessary. Kevin, what’s your take on the bullpen usage here? Do you trust Andres Munoz to close it out if it’s a tight game?
Kevin: Munoz is the closer. He’s the guy. But if the game goes into the eighth inning with the lead still marginal, you might see Gabe Speier or Eduard Bazardo come in. The manager has to be careful not to burn out Munoz if there’s a Game Three. But if it’s a must-win, yes, Munoz gets the ball. He’s the best arm they have in high-leverage spots.
Nicole: Got it. So, the offense leans on Rodriguez, Raleigh, and Naylor. The defense plays conservatively. The bullpen is managed carefully. It’s a fragile ecosystem, Kevin. One crack, and the whole thing falls apart. Let’s move to our final segment, where we give you our keys to the series and a bold prediction.
Nicole: Segment Three: Keys to the Series and a Bold Prediction. Kevin, we’ve seen the Mariners split previous series and struggle with consistency. What is the ONE thing that has to happen for Seattle to win this series against the Rockies?
Kevin: Run prevention. That’s it. The Rockies aren’t going to out-hit Seattle if Seattle is scoring three or four runs. But if the Mariners can keep the game low-scoring, say 3-1 or 4-2, they put immense pressure on the Rockies’ pitching. The key is getting strikeouts in the seventh inning. If the bullpen can escape jams without giving up runs, the Mariners win.
Nicole: I agree. And for the offense, it’s about taking walks. With so many hitters out, the remaining guys need to extend at-bats. OBP is critical. If they’re putting runners on base, they can score with less help. Now, let’s talk predictions. Back on September 17th, we predicted the Mariners would split the series against the Rockies. Does that stand?
Kevin: It stands, but I’m adjusting my confidence level. I think they win the first game. Logan Gilbert should be able to handle the Rockies’ lineup, especially if he gets early outs. So, I’m sticking with: Mariners win Game One. Then, the bullpen fatigue sets in, and they drop the next two. Final series result: 1-2 for Seattle.
Nicole: Bold call! Winning just one game in Denver is tough. But given the injury situation, I respect it. I’ll add that I think Cal Raleigh will be the MVP of the series for Seattle. He’s going to have multiple multi-hit games. He’s the engine.
Kevin: I can see that. Raleigh has been clutch all year. If the team only scores three runs, he’s likely responsible for two of them. That’s a very realistic scenario for this series.
Nicole: Alright, fans, that’s our preview. Logan Gilbert starts, the lineup is depleted but dangerous at the top, and we’re predicting a split series with a Game One win for Seattle. It’s going to be a wild ride in Denver.
