San Francisco Giants

As the San Francisco Giants prepare to host the Tampa Bay Rays on August 16, 2025, both teams are looking to bounce back from their previous matchup, where the Giants fell 7-6. The Giants currently sit at 59-63, struggling with the 26th best offense in MLB, while the Rays are slightly ahead at 60-63, boasting an average lineup ranked 14th.

On the mound, the Giants are set to start Justin Verlander, who has had a challenging season with a 1-9 record and a 4.53 ERA. Notably, Verlander was hit hard in his last outing, allowing 5 earned runs on 11 hits. Meanwhile, the Rays will counter with Adrian Houser, enjoying a more successful campaign with a 6-4 record and an impressive 2.84 ERA, although the projections suggest he may be due for some regression given his 4.40 xFIP.

The matchup favors the Rays’ pitching, especially considering the Giants’ struggles at the plate, where they rank poorly in home runs and batting average. Furthermore, the Giants’ 29th rank in stolen bases underscores their lack of offensive firepower. In contrast, the Rays have shown more offensive potential, particularly with their best hitter recently posting a .360 batting average and a 1.287 OPS over the last week.

With the Game Total set at 8.0 runs and the betting markets indicating a closely contested game, this series continues to be critical for both teams as they strive to improve their standings. The Giants, while underperforming this season, will look to leverage their home-field advantage, but they’ll need a significant turnaround against a well-rounded Rays squad.

Tampa Bay Rays Insights

• Adrian Houser – Over/Under 17.5 Pitching Outs (-105/-125)
  Generating 18.3 outs per game per started this year on average, Adrian Houser places in the 95th percentile.
  Explain: A pitcher who averages more outs per start than his Outs prop may be a good bet to go over, and visa-versa for the under.
• Yandy Diaz – Over/Under 1.5 Total Bases (+115/-150)
  Hitters such as Yandy Diaz with extreme groundball tendencies are usually more effective when facing pitchers like Justin Verlander who skew towards the flyball end of the spectrum.
  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.
• The Tampa Bay Rays have been the 10th-luckiest offense in baseball this year, according to the leading projection system (THE BAT X), and are likely to hit worse going forward
  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 Francisco Giants Insights

• Justin Verlander – Over/Under 4.5 Strikeouts (-115/-115)
  Justin Verlander’s slider percentage has jumped by 10.6% from last season to this one (19.3% to 29.9%) .
  Explain: Because sliders are one of the most effective pitches to use, a pitcher who alters his pitch mix to use more of them will often see more success as a result.
• Willy Adames – Over/Under 1.5 Total Bases (+125/-160)
  Willy Adames has negatively regressed with his Barrel% lately; his 12.2% seasonal rate has lowered to 0% in the past week’s worth of games.
  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.
• San Francisco Giants – 2H Moneyline
  According to the leading projection system (THE BAT), the San Francisco Giants’ bullpen projects as the 8th-worst out of all the teams in MLB.
  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.
