Washington Nationals

As the Washington Nationals prepare to host the Boston Red Sox on July 4, 2025, both teams find themselves in the middle of challenging seasons. The Nationals sit at 37-50, struggling to find consistency, while the Red Sox post a slightly better 43-45 record. With their playoff hopes dimming, the Nationals will look to turn things around in this Interleague matchup.

In their last outing, the Nationals narrowly lost to the Atlanta Braves, which extended their current cold streak. The Red Sox, meanwhile, are coming off an impressive victory, giving them a morale boost heading into this game.

Projecting the mound matchup, the Nationals will hand the ball to Mike Soroka, who has been somewhat unlucky this year, reflected in his 4.70 ERA and a solid 3.75 xFIP, which suggests he could improve. Soroka’s high strikeout rate of 26.3% could work in his favor against a Red Sox lineup that has struggled with strikeouts, ranking 3rd in the league in that category. On the flip side, the Red Sox will counter with Lucas Giolito, who has a better ERA of 3.99 but carries a concerning 4.96 xERA, hinting at potential regression.

Offensively, the Nationals rank 20th in the league, while the Red Sox boast the 6th best offense, showcasing a significant disparity. Despite this, both teams have been close in the betting markets, with moneylines set at -110, indicating a tightly contested matchup.

With the Nationals’ solid stolen base numbers at 7th in MLB and the Red Sox’s recent red-hot hitting from their best player, who has posted a 0.348 batting average over the last week, expect an exciting game at Nationals Park. The projections suggest that while both teams have a 50% implied win probability, the Nationals could exceed expectations if Soroka can capitalize on his strikeout potential.

Boston Red Sox Insights

• Lucas Giolito – Over/Under 5.5 Strikeouts (+110/-145)
  Because flyball batters have a notable advantage over groundball pitchers, Lucas Giolito and his 37.1% underlying GB% (via the leading projection system, THE BAT) finds himself in a tough position today facing 5 opposing GB hitters.
  Explain: This mostly has to do with the way the hitter’s swing plane interacts with the pitch trajectory, and it can create diminished performance across all categories and hidden value few are considering.
• Wilyer Abreu – Over/Under 1.5 Total Bases (+125/-160)
  Extreme groundball batters like Wilyer Abreu tend to perform better against extreme flyball pitchers like Mike Soroka.
  Explain: This mostly has to do with the way the hitter’s swing plane interacts with the pitch trajectory, and it can create boosted performance across all categories and hidden value few are considering.
• According to the leading projection system (THE BAT X), the projected batting order for the Boston Red Sox in this game has an estimated true talent wOBA of .311, which is quite a bit lower than their actual wOBA of .323 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

• Mike Soroka – Over/Under 5.5 Strikeouts (-120/-110)
  With 6 bats who bat from the opposite side in the opposing team’s projected offense, Mike Soroka will have a tough challenge while lacking the platoon advantage in most plate appearances today.
  Explain: Right-handed pitchers perform worse against left-handed hitters (and visa-versa). If several hitters hold this advantage against the pitcher, it can have a huge impact on whether he will perform well or struggle on any given day.
• Nate Lowe – Over/Under 0.5 Total Bases (-180/+135)
  Over the last week, Nathaniel Lowe’s Barrel% has experienced a negative regression, plummeting from his seasonal rate of 7.1% down to 0%.
  Explain: Barrel% measures how often a player hits the ball at the optimal exit velocity and launch angle and is a terrific measure of underlying power.
• Washington Nationals – 2H Moneyline
  The Washington Nationals bullpen projects as the 3rd-worst in MLB, per the leading projection system (THE BAT).
  Explain: Most bettors only consider the starting pitcher, but a weak bullpen sneakily creates an easier matchup for the opposing offense and boosts a game’s runs.
