San Francisco Giants

On August 8, 2025, the San Francisco Giants will host the Washington Nationals at Oracle Park in what marks the first game of their series. Both teams are struggling this season, with the Giants sitting at 58-57, while the Nationals are languishing at 45-69. The Giants are projected to start Kai-Wei Teng, who has had a rocky season with a 0-1 record and an alarming ERA of 13.50. In his last start on August 2, Teng was knocked around, allowing 5 earned runs in just 3 innings. Conversely, Jake Irvin, the Nationals’ starter, has a more respectable 8-6 record and an ERA of 4.89, but he also faced difficulties in his last outing, giving up 5 earned runs over 4 innings.

The Giants’ offense ranks 24th in MLB, showcasing their struggles in generating runs, while the Nationals sit slightly higher at 23rd. However, the projections suggest that Teng, despite his poor numbers, might have an advantage against a Nationals lineup that lacks power, ranking 27th in home runs this season. Teng’s high flyball rate could play into this matchup, as the Nationals have struggled to capitalize on such pitches.

With the Giants being favored with a moneyline of -150, they have an implied team total of 4.62 runs. The Nationals, on the other hand, are underdogs at +130 with an average implied total of 3.88 runs. Given the Giants’ home advantage and their recent win against the Nationals by a score of 4-2, they appear to have the upper hand heading into this matchup.

Washington Nationals Insights

• Jake Irvin – Over/Under Strikeouts
  Jake Irvin’s fastball velocity has dropped 2.2 mph this year (91.7 mph) below where it was last season (93.9 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.
• Daylen Lile – Over/Under Hits
  Daylen Lile has primarily hit in the back-half of the lineup this year (98% of the time), but he is projected to hit 5th on the lineup card in this matchup.
  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.
• Washington Nationals – Moneyline (+135)
  The Washington Nationals projected offense grades out as the 5th-worst of the day in terms of overall offensive skill.
  Explain: A pitcher who faces a weak opposing offense will be more likely to exceed his usual performance, particularly in terms of hits and runs, in that game.

San Francisco Giants Insights

• Kai-Wei Teng – Over/Under Pitching Outs
  Kai-Wei Teng has been given less leash than the average pitcher since the start of last season, throwing 17.6 fewer adjusted pitches-per-game than league average.
  Explain: Pitchers with a shorter leash are more likely to get pulled earlier in games and record fewer outs.
• Heliot Ramos – Over/Under Total Bases
  Heliot Ramos has seen a substantial improvement in his exit velocity lately; just compare his 94.5-mph average in the past two weeks to his seasonal 91.7-mph mark.
  Explain: Hitting the ball hard increases the chances of either a home run or the ball landing in fair territory for a hit before a fielder can get to it.
• The 7.6% Barrel% of the San Francisco Giants grades them out as the #25 club in the game this year by this standard.
  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.
