Cardinals Preview: Hjerpe’s Debut Hangover & Giants Series

St. Louis Cardinals · 2026-09-07 · Beatline Sports Podcast Network

Christine: Cooper Hjerpe threw four perfect innings in his major league debut, but the bullpen is exhausted, the lineup is decimated by injuries, and we’re flying into AT&T Park tomorrow against a desperate Giants team. How do you win when your best reliever just pitched two extra frames and your shortstop is on the IL? Stick with us.

Jason: It’s a lot to ask. We just survived a wild 10-8 win over Colorado thanks to Iván Herrera’s three hits, but now we have to look at the rotation depth and figure out who can handle the night shift in San Francisco.

Christine: Welcome to the Beatline Podcast Network! I’m Christine, and this is your daily Cardinals preview. Jason, it’s Sunday night, September 7th, and we are heading west. The Cardinals are sitting at 72-72, third in the NL Central, and they need every bit of that momentum from yesterday’s comeback.

Jason: That’s right. We split the series in Denver, beating them 10-8 after losing the previous game 10-7. Cole Carrigg had a big night for Colorado, but Herrera carried us here. Now, the Giants are waiting. They’re 59-85, fourth in the NL West, and they know they’re likely done for the year, which makes them dangerous.

Christine: Here is what we’re breaking down tonight: First, we’ll look at the pitching probables for this three-game series in San Francisco. Second, we’ll talk about the injury report—who is actually available to play? And finally, we’ll give you our keys to the series and a bold prediction for how this weekend ends.

Jason: We’ve got a long road ahead. Masyn Winn is still out, along with Willi Castro and JJ Wetherholt. That’s a lot of holes in the infield. Let’s get into it.

Christine: Alright, Segment One. Pitching. Yesterday, Cooper Hjerpe was electric. Four perfect innings. But he’s on the pitch count clock now. Who starts tomorrow night for St. Louis?

Jason: This is where it gets tricky. Kyle Leahy started the first game of the Rockies series. Andre Pallante is dealing with injuries, as we noted back on the 4th. Matthew Liberatore tossed quality innings in the finale. So, who’s the probable for the Giants series opener?

Christine: I’m seeing Michael McGreevy or Quinn Mathews mentioned in the deep rotation mix. With the bullpen so stretched, they might have to go to a starter who hasn’t thrown in a few days.

Jason: Exactly. If Hjerpe is still feeling good, maybe they pull him from the pen and start him? No, that’s too risky. He’s a rookie. You don’t rush a rookie into a heavy workload unless you have no choice. I think they lean on the left-handed options if the Giants have a right-heavy lineup.

Christine: Wait, are you saying they might rest Hjerpe? He just gave them five outs of pure dominance. That feels like a huge risk to burn a fresh arm.

Jason: Not rest. Just manage. If he starts, he goes deep. But if he comes out of the pen, they use Justin Bruihl, Luis Gastelum, Gordon Graceffo, and Brycen Mautz to bridge the gap. The ABS challenge system tracker shows their catcher usage is high, so defensive matchups matter.

Christine: Right. The Giants aren’t going to be easy. They’re playing for pride. But the Cardinals’ bullpen has to be sharp. Ryne Stanek is there for late innings, but can he handle the pressure after such a wild week?

Jason: Stanek is reliable. He’s a veteran presence. The issue is the volume. If Hjerpe throws 60 pitches tomorrow, he’s not ready for Tuesday. That means Cade Winquest and Riley O’Brien have to step up. It’s a test of depth.

Christine: So, the key is getting through six innings from the starter and not blowing the lead early. If they do that, Stanek and the rest can clean it up. But one bad inning could sink the whole series.

Jason: Agreed. We predicted a 4-3 win in the finale against Colorado, and while we didn’t get that score, we did get the win. Now, consistency is the goal. Keep the ERA low, keep the runs scored up.

Christine: Let’s take a quick breath before we dive into the lineup. This show is free because of you. If these daily breakdowns help you get through your commute or morning routine, a small tip keeps the lights on. Check the link in the episode description.

Jason: Thanks for listening. Segment Two. The lineup. Iván Herrera was the hero yesterday with three hits and two RBIs. Leo Bernal and Pedro Pages are behind the plate. Who is catching the Giants?

Christine: Herrera is hitting DH or catching. His plate discipline has been solid. But look at the outfield. Joshua Baez, Nathan Church, Jose Fermin, Thomas Saggese, Bryan Torres, Victor Scott II. That’s a lot of names for three spots.

Jason: It’s a platoon situation. The Giants will likely throw some right-handers, so they might favor Baez or Church. Jordan Walker is in right field, and he’s a consistent threat. Alec Burleson at first base is crucial for run support.

Christine: And Nolan Gorman? He’s at third base, but we have Cesar Prieto and Ramon Urias also listed. With Winn, Castro, and Wetherholt all on the IL, the infield flexibility is gone. Prieto might see more time.

Jason: Prieto is gritty. But offensively, you want Gorman. He brings the power. The problem is the middle of the order. Without Winn, who is leading off? Scott II? He’s fast, but does he get on base enough?

Christine: That’s the question. OBP is king in tight games. If they can’t get anyone on, Burleson and Walker get squeezed. And what about Blaze Jordan? He’s on the 10-day IL too. Everson Pereira as well. This roster is thin.

Jason: It’s brutal. Kyle Karros is on the 7-day. Peter Strzelecki on the 15-day. Even Kris Bryant and Jose Quintana are on the 60-day. It’s a skeleton crew. They have to rely on the guys who are actually healthy.

Christine: So, the strategy is simple: put the ball in play. Don’t strike out. Let Walker and Burleson drive them in. Herrera needs to keep up his hot streak. Three hits yesterday is the standard.

Jason: And defend well. The Giants hit some balls. If the defense lapses, they score. We saw it against Colorado. A six-run fifth inning killed us in the other game. Can’t let that happen again.

Christine: Defensive positioning is key. Shift away, but stay alert. Every error costs runs when you’re playing from behind. Okay, let’s move to the final segment. Keys to the series.

Jason: Segment Three. Keys to the series. Number one: Pitching efficiency. Get the starter through six. If you’re up 2-0 after six, you win. If you’re tied, the bullpen saves you.

Christine: Number two: Clutch hitting. Herrera showed he can do it. Can someone else step up? Maybe Burleson or Walker. We need multi-hit games from multiple players, not just one.

Jason: Number three: Bullpen management. Do not burn Stanek on Friday night if you don’t have to. Save him for Sunday. Use the lefties against lefties. Use the righties against righties. Platoon splits are real.

Christine: Bold prediction time. We’re going to sweep the Giants. 3-0. Why? Because they’re tired, we’re hungry, and we have the edge in starting pitching depth compared to their struggling staff.

Jason: I’m going to disagree slightly. I think we take two of three. The Giants will steal one game, probably the opener, because Hjerpe or the starter might struggle early. But we close it out.

Christine: I’ll take your two-out-of-three. But I’m sticking with the sweep. We need this win to stay relevant in the playoff race. 72-72 is a crossroads.

Jason: Fair enough. Either way, it’s a must-win stretch. Let’s see how the lineup shakes out.

Christine: Go Birds!
