Chicago Cubs (70-50) at Washington Nationals (59-62) | Wednesday, August 12, 2026 | 5:45 PM CT | Nationals Park, Washington, D.C.
Win number 70 is officially in the books after Tuesdayโs 8-6 shootout, and the Cubs are right back at it tonight looking to close out this series. As a Cubs fan, Iโll take an offense that can win a 14-run slugfest any day of the week, and with Washington reportedly turning back to a struggling Miles Mikolas tonight, thereโs a real chance this game turns into another high-scoring affair at Nationals Park.
Hereโs the full breakdown of tonightโs Cubs-Nationals matchup: pitching probables, odds, injuries, and my final prediction.

The Backdrop: A High-Scoring Series So Far, and More of the Same Expected Tonight
Tuesdayโs opener set the tone for this series โ 14 combined runs, both offenses trading blows, and Chicago coming out on top to reach the 70-win mark. The full season series between these two clubs is now tied 2-2, dating back to an opening-week set in April, so thereโs a genuine competitive history here despite the gap in overall records.
Chicago sits at 70-50 with a strong 35-26 mark on the road, while Washington is 59-62 and has struggled at home this season, going just 26-35 at Nationals Park. Both lineups have been productive, though โ the Nationals actually rank fifth in the NL in on-base percentage, and Chicagoโs .418 team slugging percentage ranks fourth in the league. Two good offenses, two shaky pitching staffs tonight โ thatโs the recipe for exactly the kind of game the total is pricing in.
Probable Pitchers
Chicago Cubs: David Peterson (6-7, 5.35 ERA)
Petersonโs overall numbers this season have been rough, with a 1.50 WHIP reflecting real command issues. His sinker has been especially hittable, generating a weak whiff rate and getting squared up regularly. The silver lining is his slider and curveball, both of which miss bats at a healthy clip when heโs locating them โ when Petersonโs soft stuff is working, he can still give Chicago a chance, even if itโs rarely a clean outing.
Washington Nationals: Miles Mikolas (3-9, 5.82 ERA)
Mikolas has been one of the least effective starters in baseball this season, and Chicago has a long history of hitting him hard. A 3-9 record with a near-6.00 ERA speaks for itself, and thereโs real risk of a short outing tonight that pushes an already taxed Washington bullpen into the game earlier than the Nationals would like.
Betting Odds for Cubs vs. Nationals
- Moneyline: Chicago Cubs -158 to -182 / Washington Nationals +134 to +150 (varies by book)
- Run Line: Cubs -1.5 / Nationals +1.5 (-122)
- Total: 9.5 runs
Thatโs a big number, and itโs not just a hangover from Tuesdayโs 14-run affair. Both starters carry ERAs north of 5.00 with WHIPs above 1.40, and both lineups have shown they can do damage โ Washingtonโs CJ Abrams has been a legitimate power threat all year, while Pete Crow-Armstrong has been one of the most productive hitters in baseball for Chicago. The over has hit in four of the last five meetings between these two teams, and tonightโs pitching matchup does little to argue against that trend continuing.
Key Storylines to Watch
CJ Abrams is swinging a dangerous bat. With 29 home runs on the season and an expected weighted on-base average north of .400, heโs the one hitter who can turn a comfortable Cubs lead into a nail-biter in a hurry.
Pete Crow-Armstrong keeps producing at an elite level. His expected numbers rank among the best in baseball, and heโs been the engine of this Cubs lineup for months. Against a pitcher Chicago has hit well historically, heโs a great bet to keep that trend going tonight.
Chicagoโs pitching depth is being tested. The Cubs are currently working around a long list of injured arms, including multiple starters and key bullpen pieces. That makes tonightโs assignment for Peterson even more important โ length from him would be a real gift for a taxed relief corps.
A winnable series before the schedule gets tougher. Chicago has two big rivalry series on deck against the Cardinals and White Sox once this road trip wraps up. Taking care of business against a beatable Washington team now sets up nicely for that stretch.
Prediction: Cubs vs. Nationals
Neither starter inspires much confidence as a run-suppressor tonight, and I think thatโs exactly how this game plays out โ a back-and-forth, high-scoring affair that ultimately favors the deeper, more talented Cubs lineup. Chicagoโs history of hitting Mikolas hard combined with Washingtonโs shaky bullpen depth gives me real confidence in the offense doing enough, even if Petersonโs own control issues keep this from being comfortable.
As a Cubs fan, I like this matchup and I like the number. Give me Chicago taking the series tonight in another high-scoring win.
Final Score Prediction: Chicago Cubs 8, Washington Nationals 6
