Cubs vs Nationals Key Matchups and Game Preview
Chicago has David Peterson listed as its starter, and the left-hander enters 6-7 with a 5.35 ERA and 1.50 WHIP across 106 innings, allowing 116 hits with 88 strikeouts and 43 walks. Washington has Miles Mikolas listed opposite him, with the right-hander carrying a 3-9 record, 5.82 ERA and 1.38 WHIP across 116 innings in the matchup data.
Cubs Pitching Preview
Peterson's 5.35 ERA and 1.50 WHIP point to a pitcher who has struggled to limit damage this season, allowing 116 hits and 43 walks across 106 innings. That volatility opens the door for Washington to generate offense despite James Wood's absence.
Nationals Pitching Preview
Mikolas has been especially vulnerable to the long ball with 27 home runs allowed, creating an appealing matchup for a Cubs lineup that has hit 151 homers this season. His 5.82 ERA is the highest of any starter in this matchup.

Chicago Offense Breakdown
Pete Crow-Armstrong has been Chicago's biggest offensive threat, batting .285 with a .386 OBP and .546 slugging percentage while leading the team with 27 home runs and 72 RBI. Chicago has hit 151 home runs on the season.
Washington Offense Breakdown
Washington has actually scored more runs this season, 649 to Chicago's 622, while also owning advantages in batting average (.252 to .250), slugging percentage (.440 to .418) and home runs (174 to 151). C.J. Abrams is hitting .286 with 29 home runs, 91 RBI and a .547 slugging percentage.
Cubs Recent Form
The Cubs have won four of their last five games and are riding a two-game winning streak, including Tuesday's 8-6 series-opening win over Washington.
Nationals Recent Form
Washington had won three straight before Tuesday's loss, which snapped a strong stretch heading into Wednesday's matchup.
Washington's Offensive Blow
One major piece of the Nationals' production will be absent, as James Wood is on the 10-day injured list with a left oblique strain after producing 30 homers and 73 RBI. That puts even more pressure on C.J. Abrams to carry the offense.
Washington's Additional Absences
Washington is also without catcher Drew Millas and starters DJ Herz and Josiah Gray, adding further thinness to an already shorthanded roster.
Chicago's Bullpen Concerns
Chicago has several bullpen arms sidelined, including Daniel Palencia, Hoby Milner and Gavin Hollowell, which could matter if Peterson exits early given his shaky season-long numbers.
Cubs' Depth Advantage
Chicago also has the deeper healthy lineup and the better overall team ERA, 4.07 compared with Washington's 4.73, giving the Cubs an edge even with their own bullpen questions.
CHC and WAS Betting Trends
The run line has moved in Chicago's favor over the past day, tightening from -163/+135 Monday night out to as much as -171/+141 before settling at -168/+139 by Wednesday morning, with Cubs money and tickets both running as high as 94% and 86% at various points. On the total, the number has held around 9.5 runs, with over tickets reaching 77% and under money at 60% in the most recent snapshot.
CHC and WAS Key Injuries and Things To Know
- Washington: James Wood (10-day IL, left oblique strain); Drew Millas (out); DJ Herz and Josiah Gray (starters, sidelined)
- Chicago: Daniel Palencia, Hoby Milner and Gavin Hollowell (bullpen, sidelined)
- Starting Pitchers: David Peterson confirmed for Chicago; Miles Mikolas confirmed for Washington
- Series Status: Chicago leads 1-0 after Tuesday's 8-6 win in the series opener
Cubs vs Nationals Side and Over/Under Picks
- Side Pick: Cubs -1.5 (-103) — Chicago has the deeper healthy lineup and the better team ERA, and Mikolas' vulnerability to the long ball plays into the Cubs' power.
- Total Pick: Over 9.5 (-107) — With both starters carrying ERAs above 5.00, Chicago's bullpen injuries and Washington's season-long power numbers, there are enough paths to offense despite Wood's absence.
Final Score Prediction
- Chicago Cubs: 7
- Washington Nationals: 4
Chicago also has the deeper healthy lineup and the better overall team ERA, 4.07 compared with Washington's 4.73. With both starters carrying ERAs above 5.00 and Chicago's bullpen dealing with its own injuries, this matchup sets up for the Cubs to control the game while still allowing Washington to put runs on the board.
