Arizona Diamondbacks

As the Arizona Diamondbacks host the Boston Red Sox on September 7, 2025, fans can expect an intriguing matchup at Chase Field. The Diamondbacks come in with a record of 72-71, currently sitting in a mid-table position in the National League, while the Red Sox boast a stronger 78-65 record, positioning them well in the American League. This matchup is especially significant as it marks the third game in their series.

In their most recent outing, the Red Sox managed to secure a tight victory, adding pressure to the Diamondbacks as they look to bounce back at home. Pitching will be key today, with Arizona slated to start Ryne Nelson, who holds a solid 3.57 ERA and a win-loss record of 7-3 this year. Although Nelson has been above average, his projections indicate he may struggle with allowing an average of 5.6 hits and 2.6 earned runs today. On the other hand, Boston sends Brayan Bello to the mound, whose impressive 3.07 ERA and 11-6 record reflect a season marked by reliability, although his xFIP suggests some luck this year.

Offensively, the Diamondbacks rank 5th in MLB, showcasing their power with a total of 197 home runs, while their batting average holds them at 13th. The Red Sox, with an 8th overall ranking, have excelled in batting average at 5th but sit at 13th in home runs. Both teams have proven capable of putting runs on the board, with a Game Total set at a high 9.0 runs, indicating expectations of a competitive game.

Despite their struggles in the last week, the Diamondbacks’ strong offense could exploit Bello’s tendency to give up hard contact, making this a matchup worth watching, especially as the betting lines sit evenly at -110 for both sides.

Boston Red Sox Insights

• Brayan Bello – Over/Under 4.5 Strikeouts (-105/-125)
  Because flyball hitters struggle against flyball pitchers, Brayan Bello (49.7% GB% per the leading projection system, THE BAT) is well-situated in this matchup with 3 FB hitters in the opposing team’s projected lineup.
  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.
• Alex Bregman – Over/Under 1.5 Total Bases (-105/-125)
  Arizona’s #1-ranked outfield defense on the slate poses a formidable challenge for Alex Bregman, who tends to hit a lot of flyballs.
  Explain: This player’s skill set matches up poorly with the opposing team’s defensive strength, which may lead to worse-than-usual performance.
• The Boston Red Sox have been the 8th-luckiest offense in the game this year, according to the leading projection system (THE BAT X), and are likely to hit worse the rest of the season
  Explain: When teams overperform their projected talent level, markets may overvalue them even while they are likely to perform worse in the near future.

Arizona Diamondbacks Insights

• Ryne Nelson – Over/Under 4.5 Strikeouts (-135/+105)
  It may come as a surprise, but fastballs are generally a pitcher’s least effective pitch. Ryne Nelson has utilized his off-speed and breaking pitches 8.1% less often this season (35.9%) than he did last year (44%).
  Explain: Fastballs are the one easiest pitches to hit and generate few strikeouts, so a pitcher who begins to use his fastball more often will likely be less effective than he used to be.
• Jake McCarthy – Over/Under 0.5 Hits (-215/+165)
  Jake McCarthy is projected to hit 5th on the lineup card in this game, which would be an upgrade from his 86% rate of hitting in the bottom-half of the batting order this season.
  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.
• The 9.3% Barrel% of the Arizona Diamondbacks ranks them as the #9 team in the game this year by this standard.
  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.
