Chicago Cubs (76-56) at Arizona Diamondbacks (69-62) | Tuesday, August 25, 2026 | 8:40 PM CT | Chase Field, Phoenix, AZ
Monday’s opener was pure vintage Cubs baseball — a 7-0 shutout win that pushed this offense’s recent hot streak to .269 hitting with a robust .465 slugging percentage over its last 28 games. As a Cubs fan, that’s the kind of complete performance that makes you excited heading into a bigger test tonight. Clay Holmes gets the ball looking to keep that momentum rolling, but Brandon Pfaadt has quietly been outstanding for Arizona lately too, including a dominant shutout outing against Boston at Fenway. This has all the makings of a genuinely close, well-pitched ballgame.
Here’s the full breakdown of tonight’s Cubs-Diamondbacks matchup: pitching probables, odds, and my final prediction.

The Backdrop: Chicago’s Offense Is Rolling, But Arizona’s Pitching Has Been Sneaky Good
There’s a real strength-versus-strength element to tonight’s matchup. Chicago’s bats have been the story of the last month, averaging an MLB-best 5.2 runs per game and doing damage in every possible way — gaps, over the fence, and against every type of pitching they’ve faced. That kind of sustained offensive output is exactly what makes a lineup dangerous down the stretch of a playoff race.
Arizona isn’t walking into tonight overmatched, though. The Diamondbacks are 69-62 and have real quality on the mound, with Cubs pitchers having actually thrown 21 pickoffs this season — the most in baseball — a small but telling detail about how disciplined and situationally aware this Chicago pitching staff has been all year. Both clubs bring real strengths to Chase Field tonight, and the tight odds reflect exactly that balance.
Probable Pitchers
Chicago Cubs: Clay Holmes (5-6, 2.49 ERA)
Holmes’s ERA is outstanding, even if his win total doesn’t fully reflect it — a common outcome when a pitcher’s team hasn’t given him much run support. He’s returning from a fractured right fibula and has posted just five strikeouts across his three starts since being activated, a contact-heavy approach that’s still generated results. He misses bats at a solid 24% clip overall, well ahead of tonight’s counterpart, and his command has been sharp with just a 7% walk rate.
Arizona Diamondbacks: Brandon Pfaadt (7-1, 3.39 ERA)
Pfaadt has quietly put together one of the better stretches on Arizona’s staff, including a standout outing where he shut down one of the hottest lineups in baseball for seven innings at Fenway Park. He works efficiently, generating ground balls at a strong 48% clip and walking just 6% of hitters, even if his strikeout rate sits a bit lower than Holmes’s at 17%.
Betting Odds for Cubs vs. Diamondbacks
- Moneyline: Chicago Cubs -105 to -152 / Arizona Diamondbacks -105 to +125 (wide range depending on the book)
- Total: 8.5 to 9 runs
This is one of the more interesting lines on tonight’s slate, with some books treating it as essentially a coin flip and others leaning more heavily on Chicago’s superior offensive numbers. The gap between the two starters’ ERAs is real but modest, and in a game projected to stay within a run or two, that 0.9-run difference between Holmes and Pfaadt could quietly end up being the deciding factor.
Key Storylines to Watch
Chicago’s hot streak is the headline of this series. A lineup hitting .269 with a .465 slugging percentage over the last month is the kind of form that travels well, and tonight is a good opportunity to see if it can carry over against a tougher arm in Pfaadt.
Corbin Carroll remains a dangerous name for Arizona. With a strong hard-hit rate and real power, he’s the one hitter capable of flipping this game with a single mistake pitch from Holmes.
Clay Holmes’s contact-oriented approach continues to be effective, even post-injury. He’s not missing as many bats as he did before the fibula fracture, but he’s still getting outs, and tonight’s matchup against a contact-heavy Arizona lineup plays right into that strength.
Command will likely decide this one. With both starters carrying low walk rates, the team that avoids the one big inning and keeps its bullpen fresh probably wins this game.
Prediction: Cubs vs. Diamondbacks
I like Chicago’s chances tonight, and it comes down to two things: this offense is playing its best baseball of the season, and Clay Holmes has the cleaner ERA in a matchup that projects to be close. Pfaadt is a legitimately good pitcher who’s capable of shutting down a hot lineup, as he showed against Boston, but I think Chicago’s superior overall form gives the Cubs the edge in a tight, well-pitched game.
As a Cubs fan, I like this matchup. Give me Chicago taking game two behind another strong performance from the pitching staff and continued production from this red-hot lineup.
