Team Analysis

Pittsburgh Pirates

The Pirates’ recent form is troubling, with a 0-5 skid in their last five games while scoring just 2.4 runs per contest. That lack of offensive punch has them struggling to generate any rhythm, and their season record reflects a team unable to sustain momentum. Bryan Reynolds has been one of the few steady bats, but the lineup overall has failed to provide consistent run support.

On the road, Pittsburgh has been even more vulnerable with only 22 wins against 51 losses, underscoring their lack of confidence away from home. Andrew McCutchen and Tommy Pham have delivered flashes of production, but sustained rallies have been rare. The Pirates’ offensive slump combined with their poor road record makes them a weak betting option in this spot.

  • Batting Average: 0.232
  • Total Runs Scored: 527
  • Home Runs: 105
  • OBP: 0.305
  • SLG: 0.349
  • OPS: 0.654
  • ERA: 3.87
  • WHIP: 1.23

Away Record: 22-51 • Home Record: 42-33
Last 5 Games: 0-5 (2.4 RPG)
Last 10 Games: 3-7 (3.2 RPG)


Washington Nationals

Washington has turned their recent schedule into a positive run, going 7-3 over their last 10 while averaging 5.9 runs per game. That offensive consistency, led by James Wood’s power production, has given them the ability to build early leads and maintain control. Their home record is not dominant overall, but the current uptick in scoring has made Nationals Park a favorable setting.

In their last five, the Nationals are 3-2 with 6.2 runs per game, showing that their lineup is sustaining output across series. CJ Abrams has provided timely contact to complement Wood’s power, while Luis Garcia Jr. adds balance in the middle of the order. With steady production and improved rhythm, Washington holds the advantage against a struggling opponent.

  • Batting Average: 0.245
  • Total Runs Scored: 626
  • Home Runs: 140
  • OBP: 0.308
  • SLG: 0.39
  • OPS: 0.698
  • ERA: 5.3
  • WHIP: 1.43

Away Record: 31-44 • Home Record: 30-42
Last 5 Games: 3-2 (6.2 RPG)
Last 10 Games: 7-3 (5.9 RPG)

Washington Nationals’ last 10 games have averaged 11.1 combined runs, with 7 games clearing the same number of 8.5.

Moneyline Betting Prediction

Washington Nationals’ 7-3 stretch with nearly six runs per game stands in stark contrast to Pittsburgh Pirates’ 0-5 slump and weak road record. With James Wood driving run production and the Nationals maintaining offensive rhythm at home, this matchup leans decisively toward Washington controlling the result.

Form and matchup edges favor the Washington Nationals — back them.

Over/Under Prediction

In their last five, the Washington Nationals have produced 6.2 RPG and the Pittsburgh Pirates 2.4. That output frames how this total sets up.

These teams are combining for 8.6 runs per game recently — right around the posted total of 8.5. That points toward the Over 8.5.
