Boston Red Sox

The Boston Red Sox will host the Miami Marlins on August 15, 2025, in what marks the opening game of their interleague series. Currently, the Red Sox are sitting with a solid 66-56 record, positioning them as a competitive force this season, while the Marlins trail with a 58-63 record. Despite both teams’ recent struggles—both lost their last games, with the Red Sox falling 4-1 and the Marlins suffering a 9-4 defeat—the Red Sox’s strong offensive performance this year gives them an edge.

Boston ranks as the 5th best offense in MLB, boasting impressive metrics, including a 5th rank in team batting average. Their lineup is spearheaded by a standout player who has been on a tear recently, compiling a .348 batting average and a 1.160 OPS over the last week. This offensive prowess will be crucial as they face Sandy Alcantara, who has struggled this season with a troubling 6.55 ERA and a low strikeout rate. Although Alcantara has been unlucky, as suggested by his 4.54 xFIP, the Red Sox will look to exploit his inconsistency.

On the mound, Lucas Giolito is slated to start for the Red Sox. Despite being ranked 160th among MLB starting pitchers, his ERA of 3.77 indicates that he has been somewhat effective, albeit with some luck involved this season. Giolito’s average projections suggest he will pitch around 5.7 innings while allowing approximately 2.7 earned runs.

With the advanced-stat Power Rankings reflecting that the Red Sox possess the 4th best bullpen in the league, they should be well-equipped to maintain any potential lead. Even though the Red Sox are favored with a moneyline of -165, they have a good chance to capitalize on the Marlins’ struggles and take the first game of this series.

Miami Marlins Insights

• Sandy Alcantara – Over/Under 4.5 Strikeouts (+115/-145)
  Among all SPs, Sandy Alcantara’s fastball velocity of 96.5 mph grades out in the 95th percentile this year.
  Explain: Velocity is a key component to fastball success in generating strikeouts and preventing runs.
• Otto Lopez – Over/Under 1.5 Total Bases (+105/-135)
  In terms of his wOBA and overall offense, Otto Lopez has had some very poor luck this year. His .299 mark falls considerably below the leading projection system (THE BAT X)’s version of Statcast-based Expected wOBA (xwOBA) at .341.
  Explain: xwOBA uses highly advanced Statcast data to measure a player’s overall hitting ability more accurately than actual wOBA can.
• Miami Marlins – 2H Moneyline
  According to the leading projection system (THE BAT), the Miami Marlins’ bullpen profiles as the 3rd-worst among all the teams in Major League Baseball.
  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.

Boston Red Sox Insights

• Lucas Giolito – Over/Under 16.5 Pitching Outs (-130/+100)
  Lucas Giolito has been given more leash than the average pitcher this year, recording 3.2 more adjusted pitches-per-outing than average.
  Explain: Pitchers with a longer leash are more likely to go deeper into games and record more outs.
• Wilyer Abreu – Over/Under 0.5 Hits (-210/+160)
  Wilyer Abreu has primarily hit in the top-half of the lineup this year (68% of the time), but he is projected to bat 7th on the lineup card 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.
• Jarren Duran – Over/Under 1.5 Total Bases (-115/-115)
  Jarren Duran has a 97th percentile opposite-field rate on his flyballs (38.6%) and has the good fortune of hitting them towards baseball’s shallowest LF fences in today’s matchup.
  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.
