As the Washington Nationals prepare to host the Boston Red Sox on July 5, 2025, both teams are looking to recover from a rough stretch. The Nationals currently sit at 37-51, struggling through a disappointing season, while the Red Sox are slightly better at 44-45, holding an average record. In their last meeting, the Red Sox managed a narrow victory, adding to the pressure on the Nationals as they face off in the second game of this interleague series.

Mitchell Parker is projected to take the mound for the Nationals. While Parker’s ERA stands at a respectable 4.63, his xERA of 5.41 suggests he may have been fortunate this season. With a Win/Loss record of 5-8 and a low strikeout rate of 15.8%, he will need to navigate a Red Sox lineup that ranks 6th in the league offensively. Despite his recent struggles, Parker finds himself in a favorable matchup; the Red Sox are known for their high strikeout rate, which could play into Parker’s strengths, especially considering his ability to induce weak contact.

On the other side, Walker Buehler is projected to start for the Red Sox. With a troubling ERA of 6.45 and a xFIP of 4.70, Buehler has not been at his best this season either. His low strikeout rate of 19.3% against a Nationals offense that ranks 17th could provide an opportunity for Washington to capitalize.

The Game Total is set at a high 10.0 runs, indicating expectations for a high-scoring affair. Currently, both teams have an implied team total of 5.00 runs, suggesting tight competition. With both pitchers underperforming, expect an intriguing clash as the Nationals seek to turn their season around against a Red Sox team that could be poised for a resurgence.

Boston Red Sox Insights

  • Walker Buehler – Over/Under 3.5 Strikeouts (-155/+120)
    Walker Buehler’s fastball velocity has fallen 1.5 mph this season (93.6 mph) below where it was last season (95.1 mph).
    Explain: Velocity is a key component to fastball success in generating strikeouts and preventing runs, so a pitcher whose velocity decreases will likely see worse results.
  • Carlos Narvaez – Over/Under 0.5 Hits (-235/+180)
    Carlos Narvaez is projected to bat 4th on the lineup card today, which would be an upgrade from his 57% rate of hitting in the bottom-half of the lineup this year.
    Explain: The higher in the order a player bats, the more plate appearances he will get and the more opportunities he will get to hit the Over for every market. A player who hits higher in the order than he normally does may provide extra value opportunity since the market may be based on him hitting lower.
  • According to the leading projection system (THE BAT X), the projected batting order for the Boston Red Sox today owns an estimated true talent wOBA of .311, which is considerably worse than their actual wOBA of .324 this year.
    Explain: Betting lines are often based on seasonal team quality. If today’s lineup is watered down, however, there may be value if markets aren’t accounting for the lower quality of this offense.

Washington Nationals Insights

  • Washington Nationals – 1st Five Innings (F5) Moneyline (-115)
    Mitchell Parker is an extreme flyball pitcher (35.5% FB% according to the leading projection system, THE BAT) and should be helped pitching in the #22 HR venue among all parks in this matchup.
    Explain: This pitcher’s skill set matches up particularly well with the park he’s in today, which may lead to better-than-usual performance.
  • James Wood – Over/Under 1.5 Total Bases (+125/-165)
    James Wood has seen a notable gain in his exit velocity on flyballs this season; just compare his 99.8-mph average to last season’s 96.6-mph EV.
    Explain: Most home runs are flyballs, and the harder those flyballs are hit, the more often they turn into home runs. This is a strong indicator of power.
  • Washington’s 93-mph exit velocity on flyballs grades them out as the #7 team in MLB this year by this standard.
    Explain: Most home runs are flyballs, and the harder those flyballs are hit, the more often they turn into home runs. This is a strong indicator of power.
