Boston Red Sox

As the Boston Red Sox prepare to face the Kansas City Royals on August 4, 2025, at Fenway Park, both teams find themselves in the thick of the season with different trajectories. The Red Sox, currently 62-51, are enjoying an above-average season and sit in a strong position, while the Royals, at 56-56, are hovering around .500. This matchup marks the first game of the series, adding a layer of excitement as both teams look to gain an edge.

In their most recent outings, the Red Sox have been on a roll, showcasing their potent offense, which ranks 5th in MLB. Their best hitter has been particularly hot, recording 9 hits and 8 RBIs over the past week, including 3 home runs. This offensive firepower could pose a significant challenge for Royals starter Bailey Falter, who has struggled this season and ranks among the worst pitchers in MLB.

Brayan Bello, projected to start for the Red Sox, has been a reliable presence on the mound, boasting a solid 3.19 ERA and a 7-5 record this year. While his peripherals suggest he might regress, his ability to induce ground balls (51% groundball rate) could work in his favor against a Royals lineup that lacks power, having hit just 97 home runs this season, the 3rd least in MLB.

Conversely, Falter’s low strikeout rate (15.3 K%) may be a concern against a high-strikeout Red Sox offense that ranks 3rd in MLB for strikeouts. With the game total set at a high 9.5 runs, bettors might find value in the Red Sox’s current moneyline of -155, reflecting their status as favorites in this matchup. Given the Red Sox’s strong offense and the Royals’ pitching struggles, this game could tilt in favor of Boston, especially with their implied team total of 5.21 runs.

Kansas City Royals Insights

• Bailey Falter – Over/Under 3.5 Strikeouts (-120/-110)
  Bailey Falter’s change-up usage has increased by 7.4% from last season to this one (0.6% to 8%) .
  Explain: Because change-ups are one of the most effective pitches to use, a pitcher who alters his pitch mix to use more of them will often see more success as a result.
• John Rave – Over/Under 0.5 Hits (-115/-115)
  Boston’s #2-ranked outfield defense of all teams on the slate today poses a formidable challenge for John Rave, 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.
• Salvador Perez – Over/Under 1.5 Total Bases (+105/-135)
  Salvador Perez pulls a lot of his flyballs (37.1% — 95th percentile) and sets up very well considering he’ll be hitting them towards the game’s shallowest LF fences today.
  Explain: This player’s skill set matches up particularly well with the park he’s in today, which may lead to better-than-usual performance.

Boston Red Sox Insights

• Brayan Bello – Over/Under 3.5 Strikeouts (-150/+115)
  Brayan Bello’s fastball velocity has decreased 1.2 mph this season (94.5 mph) below where it was last season (95.7 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.
• Jarren Duran – Over/Under 0.5 Hits (-225/+170)
  Jarren Duran has primarily hit in the top-half of the lineup this year (93% of the time), but he is projected to hit 7th in the batting order today.
  Explain: The lower in the order a player bats, the fewer plate appearances he will get and the fewer opportunities he will get to hit the Over for every market. A player who hits lower in the order than he normally does may provide extra value opportunity since the market may be based on him hitting higher.
• The Boston Red Sox have 4 bats in their projected batting order today with a high (i.e. over 27%) underlying K% (according to the leading projection system, THE BAT X) (Romy Gonzalez, Trevor Story, Jarren Duran, Roman Anthony).
  Explain: Teams that have multiple high-strikeout hitters will make it much easier for the opposing pitcher to record strikeouts
