Diamondbacks Preview: Rangers Series Loss, Rotation Crisis & Marlins Matchup

Arizona Diamondbacks · 2026-09-14 · Beatline Sports Podcast Network

Nicole: We just lost 7-6 to the Rangers in a game that felt like it should have been ours. Corey Seager homered for the fourth time in seven games, Jacob Latz stranded a tying run in the ninth, and suddenly our playoff hopes are hanging by a thread. But we’re not done yet. We’ve got the Miami Marlins coming to town tomorrow night, and the stakes? They couldn’t be higher.

Kevin: It’s a brutal stretch for Arizona. The D-backs are sitting at 79-71, third in the NL West, but the margin for error is basically zero. We had predictions going into this series—remember Kevin predicting a 3-1 sweep and Nicole betting on Burnes throwing seven shutout innings? Well, neither happened. The rotation is decimated, the bullpen is overworked, and now we need every single pitch to count against Miami.

Nicole: That’s right. Welcome to the Beatline Podcast Network, America’s number one daily sports podcast. I’m Nicole, and I’m joined by our lead analyst, Kevin. Today, we’re breaking down the fallout from last night’s loss, looking at who might take the mound against the Marlins, and figuring out if Ketel Marte can carry the load when the rest of the lineup goes quiet.

Kevin: Let’s set the scene. The Texas Rangers took their first road series win in two months, beating us 7-6 after winning the previous game 6-2 with a six-run fifth inning. That’s three losses in as many days. The injuries are piling up—Ryne Nelson, Tyler Locklear, Ryan Thompson, A.J. Puk, Andrew Saalfrank, Carter Baumler—all on the 60-day IL. Kyle Higashioka and Cole Winn are out too. It’s a crisis mode situation.

Nicole: And let’s not forget Lourdes Gurriel Jr. was designated for assignment yesterday, potentially ending his tenure after tearing his ACL last season. Joc Pederson is day-to-day. So, here is what we are covering today: First, the pitching probable for tonight’s Marlins series and whether we can survive the matchup. Second, the offensive reality—can Ketel Marte and Corbin Carroll keep us relevant? And third, the bold prediction for how this series ends. Let’s dive into Segment One: The Pitching Probables.

Nicole: So, Kevin, the Marlins are in town. They’re an away team for them, home for us. Who do you see starting for Arizona tonight? With the rotation so thin, do we go with Merrill Kelly again, or is there someone else in the mix?

Kevin: Honestly, Nicole, it’s a tough call. You’ve got Zac Gallen, Eduardo Rodriguez, Corbin Burnes—who we talked about yesterday—and then Michael Soroka and Brandon Pfaadt, though Pfaadt has been used more in relief recently. Given that we just lost two straight, and Burnes struggled last time out, I think they lean on experience. I’d expect either Gallen or Rodriguez to start. Burnes needs rest after that Tommy John return journey; he’s valuable, but you don’t rush him back into high-leverage spots immediately.

Nicole: Right, and remember our prediction from Friday? I said Burnes would throw seven shutout innings. He didn’t even get that far against Texas. The Rangers chewed him up. If he starts tonight, I worry about the early innings. But if it’s Gallen, that’s a different story. Gallen’s been the anchor. How does he match up against Miami’s lineup?

Kevin: Gallen’s command is elite. Against a Marlins team that isn’t exactly known for elite plate discipline, Gallen can exploit gaps in their swing mechanics. Miami’s batters tend to chase outside pitches, and Gallen lives on the edges. If he keeps his launch angle low, he’s fine. But the key is depth. Can he go seven innings? If he goes five, and the bullpen is already gassed from the last two games, that’s a recipe for disaster.

Nicole: Exactly. And speaking of the bullpen, we’ve got Taylor Clarke, Brandyn Garcia, Kevin Ginkel, Derek Law, Jonathan Loaisiga, Justin Martinez, Juan Morillo, Dennis Santana, and Brandon Pfaadt available. That’s a lot of arms, but not a lot of freshness. Justin Martinez had that historic immaculate inning earlier this year, which was incredible, but he’s pitched a lot lately. Do you trust him in the eighth tonight?

Kevin: I trust his stuff, but I question his workload. An immaculate inning is a great story, but it doesn’t mean he’s ready to eat innings late in the season. I’d want to see Kevin Ginkel or Derek Law handle the seventh, then maybe Suarez or Morillo for the eighth. You don’t burn your best relievers in a must-win game unless you have no choice. The Marlins aren’t scary offensively, but they’re dangerous if you give them cheap runs.

Nicole: Okay, so we’re leaning toward a veteran starter and a careful bullpen usage plan. But what if the starter gets hurt? Or what if the Marlins score early? We need offense. Let’s move to Segment Two: Key Hitters and Bullpen Questions.

Nicole: Ketel Marte has been on fire. Remember, we highlighted his offensive surge in our preview yesterday. He’s been the heartbeat of this lineup. Against the Rangers, he wasn’t as dominant, but he’s still the guy. Can he carry the D-backs against Miami?

Kevin: Marte is essential. His OBP is crucial because the rest of the lineup is inconsistent. When Marte gets on, he creates opportunities for everyone else. But here’s the thing: Marte faces platoon splits. If Miami starts a lefty, Marte’s numbers drop significantly. We need to check the probable starter. If it’s a right-hander, Marte is going to feast. If it’s a lefty, we need help from Corbin Carroll or Lars Nootbaar.

Nicole: Good point. And Corbin Carroll? We mentioned his injury concerns in previous episodes, but he’s healthy now. How important is his speed and contact ability against Miami’s pitchers?

Kevin: Carroll’s speed forces errors. Miami’s defense isn’t elite. If Carroll gets on base, he’s always a threat to steal second or score from first. But his strikeout rate is still an issue. He needs to make contact. If he swings at bad pitches, we’re dead in the water. I want to see him work counts, get deep into at-bats, and force the pitcher to throw strikes. That’s how you win these tight games.

Nicole: What about Nolan Arenado? He’s been solid, but not spectacular. Does he need to step up? And what about the bench? With Joc Pederson day-to-day and Gurriel gone, do we have enough depth?

Kevin: Arenado is the stabilizer. He might not hit .300 every night, but he drives in runs. In a close game, one Arenado RBI is all you need. As for the bench, it’s thin. Tim Tawa, Ildemaro Vargas, Tommy Troy—they’re fill-ins. If the starters struggle, the bench won’t save us. We need the big three—Marte, Carroll, Arenado—to deliver. Anything less, and we’re watching the Marlins take the series.

Nicole: So, the message is clear: rely on the stars, hope the bullpen holds, and pray for health. But what’s the biggest risk? Is it the pitching or the hitting?

Kevin: The pitching. Specifically, the bullpen fatigue. We’ve seen teams collapse when their relievers are overused. If the starter goes only four or five innings, and we’re asking Clarke, Garcia, or Ginkel to throw multiple innings, that’s risky. Miami will test them. I’m worried about the ninth inning. Jacob Latz was shaky last night. If he’s called upon tonight, can he close it out?

Nicole: Latz stranded a runner last night, but he gave up the run that made it 7-6. Pressure is immense. Okay, let’s wrap up our analysis in Segment Three: Keys to the Series and a Bold Prediction.

Nicole: So, Kevin, what are the keys to winning this series against the Marlins? We need to clinch something, or at least stay alive. What do you need to see from the Diamondbacks?

Kevin: Three things. First, the starter needs to go at least six innings. No heroics, just efficiency. Second, Marte and Carroll need to combine for at least four hits. Third, the bullpen needs to hold the lead in the seventh and eighth. If we do those three things, we win the series. It’s not glamorous, but it’s effective.

Nicole: I agree on the starter. Six innings is the floor. Now, for the bold prediction. Last time, I predicted a sweep, and we lost two of three. This time, I’m going bold. I predict the Diamondbacks win the series, but it’s ugly. Maybe 2-1. And I think Ketel Marte hits a walk-off home run in the final game.

Kevin: I’ll take the series win, but I’m skeptical about the walk-off homer. I think we win 2-1, and the deciding game is a low-scoring affair, maybe 3-2. I predict Zac Gallen starts Game 2 and throws seven strong innings, securing the victory. No walk-off needed. Just solid baseball.

Nicole: Gallen doing his job—that’s what we need. Alright, fans, that’s our preview. The Diamondbacks face the Marlins tonight. The rotation is thin, the bullpen is tired, but the heart of the lineup is ready. Will Marte and Carroll lead the charge? Or will the pitching struggles continue? Tune in tomorrow to find out.
