San Diego Padres

On August 9, 2025, the San Diego Padres will host the Boston Red Sox at Petco Park for the second game of a compelling interleague matchup. Both teams have been performing well this season, with the Padres holding a record of 64-52 and the Red Sox slightly ahead at 65-52. The stakes are high as each team looks to gain momentum in a tightly contested race.

In their previous game, the Padres dominated the Red Sox, showcasing their strong bullpen, which ranks as the 2nd best in MLB according to advanced-stat Power Rankings. This could be a significant advantage, especially considering their projected starter, Michael King, is having a breakout year. King, who is currently ranked as the 28th best starting pitcher in MLB, has an impressive 2.59 ERA and a solid 4-2 record over 10 outings. His strong strikeout rate of 28.4% gives him an edge against a Red Sox lineup that has struggled with strikeouts, ranking 4th in the league.

On the other hand, Lucas Giolito, projected to start for the Red Sox, has been less effective this season. Although his 3.57 ERA is decent, he is viewed as a below-average pitcher by the projections. His tendency to allow over 5 hits and nearly 2 walks per game could spell trouble against a Padres offense that, while ranked 22nd overall, does have the potential to capitalize on pitching mistakes.

As the Padres are favored with a moneyline of -150, bettors might find value in the Padres’ strong bullpen and King’s ability to handle a high-strikeout lineup. This matchup promises tension and excitement as both teams look to assert themselves in a pivotal moment of the season.

Boston Red Sox Insights

• Lucas Giolito – Over/Under 4.5 Strikeouts (+110/-140)
  Among all starting pitchers, Lucas Giolito’s fastball spin rate of 2234 rpm is in the 19th percentile this year.
  Explain: Spin rate is a key component to fastball success in generating strikeouts and preventing runs.
• Wilyer Abreu – Over/Under 0.5 Hits (-130/+100)
  Wilyer Abreu has primarily hit in the top-half of the batting order this season (71% of the time), but he is projected to hit 7th in the batting order in this game.
  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 been the 5th-luckiest offense in the majors this year, according to the leading projection system (THE BAT X), and are likely to perform worse in future games
  Explain: When teams overperform their projected talent level, markets may overvalue them even while they are likely to perform worse in the near future.

San Diego Padres Insights

• Michael King – Over/Under Pitching Outs
  The leading projection system (THE BAT X) expects Michael King to be limited in today’s game, projecting a maximum of 76 pitches.
  Explain: A pitcher who is on a pitch count is likely to be pulled from the game earlier, record fewer outs, and generate fewer strikeouts.
• Luis Arraez – Over/Under 1.5 Total Bases (+130/-170)
  Luis Arraez’s exit velocity on flyballs has fallen off this season; his 87.9-mph average last season has fallen to 85.6-mph.
  Explain: Most home runs are flyballs, and the harder those flyballs are hit, the more often they turn into home runs. This is a strong indicator of power.
• San Diego Padres – 2H Moneyline
  The San Diego Padres bullpen grades out as the best in the majors, via the leading projection system (THE BAT).
  Explain: Most bettors only consider the starting pitcher, but a strong bullpen sneakily creates a tougher matchup for the opposing offense and suppresses a game’s runs.
