San Francisco Giants

As the San Francisco Giants prepare to face the Baltimore Orioles on August 30, 2025, at Oracle Park, they come off a resounding victory, having defeated the Orioles 15-8 in their previous matchup. Both teams are struggling this season, with the Giants sitting at 67-68 and the Orioles at 60-75, indicating an average and a bad season, respectively.

The Giants will send Carson Seymour to the mound, who has had a challenging year, with a 0-1 record and only 10 appearances out of the bullpen. Although Seymour’s ERA stands at a decent 3.74, his 4.44 xFIP indicates he might have been a bit lucky, projecting him to pitch just 3.9 innings today while allowing 2.2 earned runs on average. In contrast, the Orioles will counter with Trevor Rogers, who has been a standout this season, sporting a remarkable 1.40 ERA and a 7-2 record. Rogers’ recent performance included a solid 7-inning outing with just 1 earned run in his last start on August 24, 2025.

Offensively, the Giants rank 25th in Major League Baseball, struggling particularly with a .228 batting average. Their best hitter has been on a hot streak, boasting a .450 batting average over the last week, which could provide a glimmer of hope. The Orioles, while not stellar, rank 20th offensively and possess some power, sitting 13th in home runs this season.

With the Giants’ bullpen ranked 25th and the Orioles’ at 29th, both teams face challenges in closing out games. The current moneyline reflects a narrow margin, favoring the Orioles at -120, but the Giants have the potential to pull off an upset, particularly if their best hitter continues his recent success. This matchup could be tighter than the records suggest, making it a compelling contest for bettors.

Baltimore Orioles Insights

• Trevor Rogers – Over/Under 5.5 Strikeouts (-105/-125)
  Trevor Rogers has utilized his four-seamer 8.9% more often this season (40.6%) than he did last year (31.7%).
  Explain: Fastballs are the one easiest pitches to hit and generate few strikeouts, so a pitcher who begins to use his fastball more often will likely be less effective than he used to be.
• Dylan Beavers – Over/Under 0.5 Total Bases (-145/+115)
  Extreme groundball bats like Dylan Beavers are generally more successful against extreme flyball pitchers like Carson Seymour.
  Explain: This mostly has to do with the way the hitter’s swing plane interacts with the pitch trajectory, and it can create boosted performance across all categories and hidden value few are considering.
• Ryan Mountcastle – Over/Under 1.5 Total Bases (+125/-160)
  Ryan Mountcastle has a 94th percentile opposite-field rate on his flyballs (37.5%) and sets up very well considering he’ll be hitting them out towards baseball’s 2nd-shallowest RF fences today.
  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.

San Francisco Giants Insights

• Jung Hoo Lee – Over/Under 0.5 Hits (-140/+110)
  Jung Hoo Lee is penciled in 7th on the lineup card in this matchup, which would be a downgrade from his 70% rate of hitting in the top-half of the batting order this year.
  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 San Francisco Giants have been the 2nd-unluckiest offense in baseball this year, according to the leading projection system (THE BAT X), and are likely to perform better in the future
  Explain: When teams underperform their projected talent level, markets may undervalue them even while they are likely to perform better in the near future.
