Arizona Diamondbacks

As the Arizona Diamondbacks host the Cleveland Guardians on August 20, 2025, both teams are looking to gain momentum in a tightly contested series. In their last matchup, the Diamondbacks edged out the Guardians 6-5, putting them in a favorable position as they aim for their second straight victory. Arizona currently holds a record of 61-66, while Cleveland stands at 64-61, making this an intriguing Interleague clash.

Tonight’s matchup features a tale of two pitchers. Brandon Pfaadt, projected to start for Arizona, has had a mixed season, with a 12-8 record and a 5.08 ERA. While he ranks as the 168th best starting pitcher in MLB according to Power Rankings, the projections indicate he may be due for a turnaround, as his 4.10 xFIP suggests he has been somewhat unlucky this year. Pfaadt’s average projection of 5.4 innings pitched and 2.8 earned runs allowed hints at a performance that could keep the Guardians at bay.

On the other side, Parker Messick is set to take the mound for Cleveland. His struggles are reflected in his projections, which highlight a short outing of just 4.8 innings and an average of 2.7 earned runs. With both pitchers facing offenses that feature stark contrasts in performance, the Diamondbacks boast the 4th best offense in MLB, while the Guardians languish at 29th. Arizona’s lineup has been explosive, ranking 5th in home runs, which could be a significant factor against a struggling Guardians bullpen ranked 27th.

With a game total set at 9.0 runs, betting markets see this as a closely contested affair. The Diamondbacks’ implied team total of 4.50 runs aligns with their recent offensive prowess, making them a strong contender to override the Guardians’ recent struggles at the plate. As the game unfolds, the Diamondbacks’ offensive depth may prove decisive in this pivotal matchup.

Cleveland Guardians Insights

• Parker Messick – Over/Under Pitching Outs
  Compared to league average, Parker Messick has been given a shorter leash than the average pitcher this year, recording an -9.6 fewer adjusted pitches each game.
  Explain: Pitchers with a shorter leash are more likely to get pulled earlier in games and record fewer outs.
• Jose Ramirez – Over/Under 1.5 Total Bases (-115/-115)
  Jose Ramirez is an extreme flyball hitter and squares off against the strong outfield defense of Arizona (#2-best of all teams on the slate).
  Explain: This player’s skill set matches up poorly with the opposing team’s defensive strength, which may lead to worse-than-usual performance.
• Ranking steepest in Major League Baseball this year, Cleveland Guardians hitters as a group have notched a 16.6° launch angle (a reliable stat to assess the ability to lift the ball for power).
  Explain: A high launch angle generally means the hitter can lift the ball into the air well, which is a key component for power and home runs.

Arizona Diamondbacks Insights

• Brandon Pfaadt – Over/Under 4.5 Strikeouts (+110/-140)
  Despite conventional wisdom, fastballs are generally a pitcher’s least effective pitch. Brandon Pfaadt has used his non-fastballs 7% more often this season (51.4%) than he did last year (44.4%).
  Explain: A pitcher who limits has fastball usage will instead heavily use change-ups, curveballs, sliders, etc. These are far more effective pitches at preventing runs and generating strikeouts.
• Blaze Alexander – Over/Under 0.5 Hits (-195/+150)
  Blaze Alexander has primarily hit in the back-half of the batting order this year (94% of the time), but he is projected to hit 5th in the batting order in this game.
  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.
• Arizona Diamondbacks – 2H Moneyline
  The Arizona Diamondbacks bullpen ranks as the 3rd-worst in the majors, 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.
