Arizona Diamondbacks

On June 27, 2025, the Arizona Diamondbacks will host the Miami Marlins at Chase Field for the first game of their series. Arizona sits at 41-39 this season, showcasing an average performance, while Miami struggles with a record of 34-45. The Diamondbacks have a strong offense, ranking 3rd in MLB, and they are coming off a loss to the San Francisco Giants on June 25, where they fell 7-3. In contrast, the Marlins recently broke a losing streak with a 12-5 victory over the Philadelphia Phillies.

Merrill Kelly is projected to take the mound for the Diamondbacks. He has been solid this season with a 7-3 record and a commendable 3.39 ERA, ranking as the 49th best starting pitcher in MLB. However, his 3.91 xERA suggests he may have had some luck on his side. Kelly’s last outing on June 21 was impressive, as he pitched 6 innings, allowing just 2 earned runs while striking out 7 batters.

Eury Perez will start for the Marlins, but he faces a tough challenge. With a 0-2 record and a troubling 6.17 ERA, he ranks as the 70th best starting pitcher. Perez has struggled to find his rhythm, and his high walk rate of 13.0% could be problematic against a patient Diamondbacks lineup that ranks 5th in walks drawn.

Given the offensive firepower of the Diamondbacks, who have hit 115 home runs this season, they should capitalize on Perez’s tendency to allow fly balls. The projections favor Arizona significantly in this matchup, with a high implied team total of 4.82 runs. With the Diamondbacks looking to bounce back from their recent loss, they are positioned well to take advantage of Miami’s struggles.

Miami Marlins Insights

• Miami Marlins – 1st Five Innings (F5) Moneyline (+135)
  Eury Perez is an extreme flyball pitcher (41.3% FB% according to the leading projection system, THE BAT) and should be aided by pitching in the #29 HR venue in MLB today.
  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.
• Jesus Sanchez – Over/Under 1.5 Total Bases (+135/-180)
  Extreme groundball batters like Jesus Sanchez generally hit worse against extreme groundball pitchers like Merrill Kelly.
  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.
• The Miami Marlins have 3 bats in their projected offense today with a high (i.e. over 27%) underlying K% (per the leading projection system, THE BAT X) (Kyle Stowers, Heriberto Hernandez, Connor Norby).
  Explain: Teams that have multiple high-strikeout hitters will make it much easier for the opposing pitcher to record strikeouts

Arizona Diamondbacks Insights

• Merrill Kelly – Over/Under 5.5 Strikeouts (-115/-115)
  With 6 hitters who share his handedness in the opposing team’s projected batting order, Merrill Kelly ought to benefit from holding the platoon advantage in most plate appearances in today’s matchup.
  Explain: Right-handed pitchers perform better against right-handed hitters (and the same for lefties). Having this advantage against a lot of opposing hitters can have a huge impact on whether a pitcher will perform well or struggle on any given day.
• Alek Thomas – Over/Under 0.5 Total Bases (-155/+120)
  Alek Thomas has struggled with his Barrel% of late; his 7.9% seasonal rate has fallen off to 0% in the past two weeks.
  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.
• Arizona Diamondbacks – 2H Moneyline
  The Arizona Diamondbacks bullpen grades out as the 9th-worst in the game, according to 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.
