Chicago Cubs (76-57) at Arizona Diamondbacks (70-62) | Wednesday, August 26, 2026 | 2:40 PM CT | Chase Field, Phoenix, AZ
Arizona snuck away with a 5-4 win Tuesday to even this series, and now Chicago closes out the road trip against arguably the best pitcher the Cubs will see all week. As a Cubs fan, I won’t pretend this is an easy assignment — Eduardo Rodriguez has been nearly unhittable over his last several starts, and Matthew Boyd has had a rougher stretch of his own lately. This is the kind of afternoon getaway game that tests a lineup’s discipline more than its power.
Here’s the full breakdown of today’s series finale at Chase Field: pitching probables, odds, and my honest final prediction.

The Backdrop: This Series Has Been a Genuine Back-and-Forth Battle
This series has delivered exactly the kind of competitive baseball you’d expect between two clubs jockeying for playoff positioning. Chicago dominated Monday behind Clay Holmes before Arizona answered right back Tuesday, evening things at a game apiece. Now the rubber match arrives, and it comes with a real wrinkle: Chicago’s superior 76-57 record and second-place standing in the NL Central don’t mean much against the specific pitcher Arizona is trotting out today.
Beyond just today’s game, this series carries a little extra weight — if these two clubs happen to finish the season with identical records, head-to-head results serve as MLB’s first postseason tiebreaker. That’s not the deciding factor in how either team approaches today, but it’s a reminder that every game between contenders like these carries stakes beyond just the standings.
Probable Pitchers
Arizona Diamondbacks: Eduardo Rodriguez
Rodriguez is playing the role of a true stopper today, and his recent stretch has been remarkable — back-to-back starts of seven scoreless innings on just two hits against Atlanta and the Dodgers, following a combined 13.2 scoreless innings against the Padres and Pirates before that. He did get knocked around in his most recent outing against Boston, so there’s some hope that was the start of a correction, but this is about as tough a pitcher as Chicago will face all season when he’s right.
Chicago Cubs: Matthew Boyd
Boyd has struggled in his recent outings, a rough stretch for a pitcher who was one of the more dependable arms in this rotation for most of the summer. Today’s matchup against a red-hot Arizona lineup and an even hotter opposing starter puts real pressure on him to settle down and give Chicago length, even if a dominant outing isn’t the most realistic expectation.
Betting Odds for Cubs vs. Diamondbacks
- Moneyline: Arizona Diamondbacks favored, with recent modeling giving the Diamondbacks in the range of 52-55% win probability
- Total: Expect a total on the lower end given both the pitching matchup and Rodriguez’s recent dominance, likely in the 7.5-to-8-run range
This is a rare instance this series where Chicago isn’t the favorite, and it’s almost entirely because of who’s on the mound for Arizona. Even with the Cubs holding the better overall record and offensive numbers, Rodriguez’s recent form is legitimately special, and the market is respecting that in a big way today.
Key Storylines to Watch
Alex Bregman and Pete Crow-Armstrong remain Chicago’s best weapons. Both have posted a 162 wRC+ in the second half, tied for sixth-best in all of baseball, with a combined 22 home runs in that stretch. If anyone on this roster is going to solve Rodriguez today, it’s one of these two.
Can Boyd find his form again? After a stretch of struggles, today is a tough spot to expect a bounce-back, but a Cubs team that’s shown real resilience all year needs him to at least keep this competitive.
Rodriguez’s one recent blemish offers a sliver of hope. Getting hit hard by Boston last time out is the only real crack in an otherwise dominant recent stretch. If that carries over even a little, Chicago’s patient approach at the plate could find some openings.
A tiebreaker-relevant game, even if it doesn’t feel like one today. With head-to-head results potentially mattering later in the season, today’s outcome carries a bit of extra weight beyond just breaking this series tie.
Prediction: Cubs vs. Diamondbacks
I’d love to say Chicago’s offense breaks through today, but Eduardo Rodriguez has been about as good as any pitcher in baseball over his last several starts, and Matthew Boyd isn’t walking in with much recent momentum of his own. I think this is a tough one for the Cubs to win, even with Bregman and Crow-Armstrong both playing at an elite level right now.
As a Cubs fan, I’m hoping for a competitive game and a chance to make Rodriguez work. But realistically, I think Arizona closes out the series today behind one of the best pitching performances Chicago will see all season.
