Diamondbacks vs Cubs Prediction 26 August 2026
📡 The opening game of the series saw Chicago cruise to a commanding 7-0 shutout. Kevin Gausman delivered seven scoreless innings, while Arizona managed just five singles all night. On Tuesday, the hosts have a solid chance to shift the momentum: Brandon Pfaadt has been impressive since rejoining the rotation. The Cubs counter with Clay Holmes, who boasts a 2.49 ERA. After Monday’s blowout, this pitching matchup suggests a much more tightly contested evening is on the cards.

Head-to-head statistics Diamondbacks - Cubs

Arizona Diamondbacks Team Overview
Following Monday’s defeat, Arizona’s record stands at 69-63. The absence of Ketel Marte continues to impact their lineup depth; the second baseman remains on the injured list with knee inflammation and isn’t expected back until late in the month. In the series opener, the Diamondbacks failed to register any extra-base hits. Corbin Carroll and the heart of the order are still capable of sparking a big inning, but the offense is now forced to operate without one of the club’s top hitters.

Chicago Cubs Team Overview
Chicago followed up their 19-run outburst in Seattle by plating another seven runs in Arizona, racking up an impressive 26 runs over two games. That kind of offensive surge is eye-catching, though even a potent lineup like the Cubs’ will struggle to sustain it night in and night out. On Monday, the Cubs got home runs from Michael Conforto and Carson Kelly, once again building an early cushion. However, they’re set to face a much stiffer challenge at the start of Game 2: Brandon Pfaadt, prior to his last outing in Boston, had gone several weeks without allowing opponents to put together any big innings.

⚾ Projected Starting Pitchers
Brandon Pfaadt enters with a 7-1 record and a 3.39 ERA. His most recent outing in Boston put a dent in an otherwise impressive August run-he allowed five earned runs over 6.2 innings, surrendering three home runs. Prior to that, Pfaadt had strung together three consecutive starts in which he gave up just one earned run across 21.2 innings, including two outings where he tossed seven scoreless frames.
Clay Holmes stands at 5-6 with a 2.49 ERA and a 1.11 WHIP. Since joining Chicago, he’s given up five earned runs in 16 innings of work. Holmes has been particularly sharp in his last two starts: he threw 7.2 shutout innings against St. Louis and limited the White Sox to just one run over 5.1 frames. He rarely gives up extra-base hits and is currently doing an excellent job of keeping runners off the bases.
⭐ Editor's Pick
On Monday, Chicago dictated the tempo from start to finish, but Tuesday’s matchup promises a much tighter contest on the mound from both sides. Pfaadt was on a stellar run before heading to Boston, while Holmes has been consistently reliable for several weeks. Arizona are missing Marte and just went nine innings without an extra-base hit. The Cubs, meanwhile, are trending in the opposite direction form-wise, but the 9.5-run line still leaves plenty of room, even if the visitors plate five or six runs. The late innings also look manageable, provided both starters can go at least five or six frames. Our pick: under 9.5 total runs.
