Cubs vs Pirates Preview: Imanaga's Revenge & Bullpen Depth Test

Chicago Cubs · 2026-09-12 · Beatline Sports Podcast Network

Stephanie: Alex Bregman just blasted his twenty-fifth home run, Shota Imanaga pitched six effective innings, and the Chicago Cubs finally broke that four-game skid with a dominant twelve-to-two victory over the Pittsburgh Pirates. But here is the twist: the very same Pirates are back in town tonight for Game Two, and they are riding a momentum shift of their own. We have the full breakdown of who starts on the mound, which injured stars might be lurking near the lineup, and why this bullpen battle is going to define the NL Central race.

Sean: It is great to be back with you all. The Cubs are sitting at eighty-two wins and sixty-six losses, holding second place in the division, but the margin for error is shrinking every single day. We talked about the severe injury list yesterday, and today we see how those absences actually play out against a Pirates team that refuses to quit. Let’s get into it.

Stephanie: Welcome to the Beatline Podcast Network, where we live for the daily grind of baseball. I’m Stephanie, joined by my analyst Sean. Before we dive into the pitching matchup, let’s look at what’s coming up. First, we’ll break down the probable pitchers for tonight’s clash and analyze the platoon splits that could favor one side. Second, we’re going deep into the injury report, specifically Dansby Swanson’s potential return timeline and the heavy toll on the relief corps. And third, we’ll give you our bold predictions for whether the Cubs can sweep this series or if Pittsburgh steals a win. Stick with us, because the stakes are higher than ever.

Stephanie: Let’s start right where the rubber meets the road: the pitching duel. Yesterday, Shota Imanaga was lights out, tossing six solid innings while the offense provided ample support. With the series tied one game to none, do you think the Cubs stick with Imanaga again, or do they make a strategic adjustment?

Sean: I would be surprised if they don’t. Imanaga showed incredible command yesterday, limiting the Pirates to two runs while keeping their core hitters off balance. His ability to induce weak contact is vital when you are dealing with a depleted bullpen. If he can go six innings again, it saves your relievers for the late frames, which is exactly what you need right now.

Stephanie: Agreed. It feels like the safest bet given the circumstances. But looking at the roster, we have Matthew Boyd, Aaron Civale, Kevin Gausman, and Clay Holmes available as starters. Does having that depth change how you view the rotation management for the final stretch?

Sean: It definitely gives Craig Counsell flexibility, but I worry about the rest days. If Imanaga goes seven tonight, you might burn through a few days of rest for the next starter. In a tight playoff race, preserving arms is key. However, against a Pirates lineup that struggled to generate consistent power yesterday, sticking with your ace is usually the right move. You want to control the game early rather than relying on a bullpen that has been decimated by injuries.

Stephanie: That brings us directly to the elephant in the room: the injuries. We know Gavin Hollowell, Edward Cabrera, Hunter Harvey, Shelby Miller, Tyler Austin, Esmerlyn Valdez, Kirby Yates, Braxton Ashcraft, Isaac Mattson, and Mitch Keller are all on the IL or Day-To-Day status. That is a massive chunk of personnel missing. How does this impact the defensive positioning and the way the Cubs manage their infielders?

Sean: It forces them to be incredibly creative. With so many arms unavailable, the starting pitcher has to eat more innings. Defensively, you might see shifts based on spray charts rather than traditional alignments, especially since players like Dansby Swanson are still recovering. Every ground ball becomes critical because there isn’t a fresh arm in the bullpen ready to cover for a mistake. It puts a huge premium on first-pitch strikes.

Stephanie: Speaking of Swanson, manager Craig Counsell mentioned before Friday’s game that the shortstop could be back in the lineup next week. For tonight, though, he’s likely still out. How much does his absence hurt the offensive production, particularly regarding plate discipline and OBP?

Sean: Significantly. Swanson provides stability at the top of the order and gets on base consistently. Without him, you’re relying on guys like Nico Hoerner and Michael Busch to fill that void. They are capable, but losing that steady presence means more pressure on the middle of the lineup to drive in runs. It also affects the defensive range behind the pitcher, which ties back into why the starter needs to perform well.

Stephanie: So, if Imanaga doesn’t get that sixth inning, the bullpen takes a beating. Let’s talk about the relievers. We have Javier Assad, Daniel Palencia, Ryan Rolison, Caleb Thielbar, Trent Thornton, Jacob Webb, and Ryan Zeferjahn. Who stands out as the most reliable option in this current state?

Sean: Jacob Webb has been a workhorse, despite the concerns we raised yesterday. He’s shown resilience and can handle high-leverage situations. But with the strain on his arm, using him in a save situation tonight might be risky. I’d lean toward Daniel Palencia or Javier Assad for the eighth inning, depending on who has been resting. The key is avoiding overuse; if you burn them out now, you lose them for October.

Stephanie: Exactly. You can’t afford to blow the bridge before you even cross it. So, assuming Imanaga goes five or six innings, we’re looking at a three-inning finish from the bullpen. That’s a tall order with these limitations. Let’s shift gears to the other side of the ball. The Pirates are seventy-four and seventy-four, third in the NL Central. They lost badly yesterday, but they’ve got talent. Who should we watch for offensively?

Sean: The Pirates always have dangerous bats, even after a tough loss. They will come out swinging to try and salvage some pride. Look for their center fielder and leadoff hitter to apply pressure on the bases. Speed can disrupt a pitcher’s rhythm, and if the Cubs’ defense is still adjusting to the missing pieces, that could create scoring opportunities. It’s not just about power; it’s about creating chaos.

Stephanie: Chaos is exactly what you don’t want when your bullpen is thin. Alright, let’s move into Segment Two. We’ve covered the pitching and the injuries. Now, let’s talk about the hitters. Alex Bregman had a monster game yesterday with three hits, including that homer. Can he sustain that kind of performance against a different pitcher?

Sean: Bregman is a proven commodity. His launch angle and exit velocity metrics suggest he can hit anywhere. Against a lefty, he might struggle slightly due to platoon splits, but against a right-handed starter, he’s a threat every time he steps in. The Cubs need him to replicate that energy tonight. If he gets hot, it opens up lanes for the guys batting behind him.

Stephanie: Right. And who else needs to step up? We have Ian Happ, Seiya Suzuki, Pete Crow-Armstrong, and Matt Shaw in the outfield mix. How do you see the lineup stacking up without Swanson?

Sean: Ian Happ is crucial. He provides both power and on-base skills. Seiya Suzuki is another guy who can change the game with one swing. Pete Crow-Armstrong brings speed and defense, which is valuable in tight games. Matt Shaw is emerging as a consistent contributor. The key is getting runs in clusters. If they can string together two or three hits in an inning, it puts immediate pressure on the Pirates’ pitcher.

Stephanie: Cluster hitting is essential. We saw that yesterday with the twelve-run explosion. But the Pirates aren’t just a bad team; they’re fighting for relevance in the standings. Do you think the Cubs are underestimating their opponent’s desperation?

Sean: Never underestimate a team playing for pride. The Pirates know their season is slipping away, and they will play harder in September than they did in July. This is a trap game waiting to happen. The Cubs cannot take their foot off the gas. Every pitch matters. Every at-bat matters. Complacency is the enemy of success in the playoffs.

Stephanie: That’s a serious warning. So, how do the Cubs avoid that trap? By focusing on execution. Let’s talk about the ABS challenge system tracker. It ranks batters, catchers, teams, and umpires throughout the season. Does this data influence how the Cubs approach their at-bats against the Pirates’ catching and umpiring crew?

Sean: Absolutely. Understanding the strike zone tendencies of the umpire is part of modern baseball. If the umpire has a low strike zone, the Cubs can lay off borderline pitches and work the count. If he’s tight, they need to be aggressive on hittable pitches. It’s all about maximizing plate discipline. The ABS tracker helps identify trends that can be exploited strategically.

Stephanie: Strategic exploitation. Love that. Now, let’s touch on the defensive side again. With Miguel Amaya and Carson Kelly behind the plate, how important is their framing in this game?

Sean: Critical. Good framing can turn a ball into a strike, saving a batter from a walk and keeping the pitcher in rhythm. In a game where margins are thin, those extra outs matter. Amaya has improved significantly, and Kelly provides experience. Together, they need to ensure the umpire sees the Cubs’ perspective of the zone.

Stephanie: Framing wins games. It’s that simple. Okay, moving into Segment Three. We’ve analyzed the pitchers, the hitters, the injuries, and the strategy. Now it’s time for our bold predictions. Sean, last time you predicted the Pirates would sweep the two-game series. Clearly, that didn’t happen. How do you adjust your outlook for tonight?

Sean: I respect the correction. The Cubs showed their teeth yesterday. My prediction for tonight is that the Cubs win, but it won’t be easy. I expect a low-scoring affair, maybe something like three-to-one. The Pirates will keep it close, but Imanaga’s dominance and Bregman’s clutch hitting will tip the scales. The Cubs take Game Two.

Stephanie: I’m leaning towards a sweep. The momentum is with Chicago. After breaking that skid, the confidence is high. I think the Cubs capitalize on the Pirates’ fatigue and complete the series win. But I agree with Sean—it won’t be a blowout. It will be a gritty, hard-fought contest.

Sean: A gritty contest is exactly what we need to see. The Cubs have the talent, but they need to execute flawlessly. No errors. No wild pitches. Just pure baseball. If they do that, the result will follow.

Stephanie: And if they don’t? Well, that’s why we listen to the podcast. To stay informed and prepared for whatever happens. Let’s recap the keys to the series: Imanaga must eat innings, the bullpen must survive without overuse, and the offense must cluster hits around Bregman’s production. It’s a lot to ask, but that’s baseball.

Sean: Precisely. The margin for error is non-existent. The Cubs are playing for position in the standings, and every game counts. Tonight is no different. They need to bring the same intensity they showed yesterday and maintain it for nine innings.
