The Washington Nationals defeated the Arizona Diamondbacks 10–7 on July 26 at Nationals Park in a high-scoring affair that exceeded the Vegas total of 10.5 runs. The Nationals' offense proved decisive, collecting 15 hits and four home runs while driving in nine runs, posting a .776 OPS despite striking out just four times. Arizona's pitching struggled mightily, allowing nine earned runs on 15 hits with an ERA of 4.27, though the Diamondbacks' lineup managed seven RBIs on nine hits and two homers. Washington's pitching was similarly vulnerable, surrendering seven earned runs with a 4.78 ERA and issuing seven walks, yet the Nationals' clean defense and timely hitting provided the margin. The Diamondbacks drew seven walks themselves but couldn't capitalize fully, leaving their run production short despite respectable plate discipline. The Nationals' four-homer performance and superior run-scoring efficiency offset Arizona's efforts in a slugfest that favored the home team. Washington's run differential on this date suggests continued offensive momentum heading into the next rotation.
