Atlanta Braves

As the Atlanta Braves prepare to host the Seattle Mariners on September 5, 2025, they find themselves struggling this season with a record of 63-77. Despite their underwhelming performance, the Braves are slight betting favorites with a moneyline of -140. In contrast, the Mariners are enjoying an above-average season at 73-67, highlighted by their power-hitting lineup that ranks 3rd in MLB with 200 home runs.

In their last outing, the Braves’ ace, Chris Sale, will take the mound, bringing an impressive ERA of 2.45, although his xFIP suggests he might have been a bit lucky this season. Sale projects to pitch around 5.6 innings, allowing about 2.2 earned runs while striking out 7.7 batters—solid numbers that could give him an edge against a high-strikeout Mariners offense. Moreover, Sale’s capability to keep the strikeouts high aligns well with the Mariners’ tendency to swing and miss, making this matchup intriguing for fans and bettors alike.

Logan Gilbert, the Mariners’ starter, has a respectable ERA of 3.73 but is projected to face a Braves offense that, while averaging in the middle tier for runs, struggles with flyballs. Gilbert’s low walk rate of 6.2% may help him neutralize the Braves’ patient approach, potentially giving the Mariners an advantage.

The Game Total is set at a low 7.5 runs, indicating expectations of a pitcher’s duel. With the Braves needing a win to boost their morale and the Mariners looking to solidify their playoff positioning, this game has significant implications for both teams.

Seattle Mariners Insights

• Logan Gilbert – Over/Under 6.5 Strikeouts (+115/-150)
  Despite conventional wisdom, fastballs are generally a pitcher’s least effective pitch. Logan Gilbert has utilized his secondary pitches 5.3% less often this season (62.4%) than he did last season (67.7%).
  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.
• Victor Robles – Over/Under Hits
  Victor Robles has experienced some positive variance in regards to his batting average since the start of last season; his .299 mark is quite a bit higher than his .248 Expected Batting Average, based on the leading projection system (THE BAT X)’s interpretation of Statcast data.
  Explain: xBA uses highly advanced Statcast data to measure a player’s batting average ability more accurately than actual batting average can.
• Cal Raleigh – Over/Under 0.5 Total Bases (-160/+125)
  Cal Raleigh pulls many of his flyballs (43.4% — 100th percentile) and has the misfortune of hitting them towards baseball’s 2nd-deepest LF fences in today’s matchup.
  Explain: This player’s skill set does not match up particularly well with the park he’s in today, which may lead to worse-than-usual performance.

Atlanta Braves Insights

• Chris Sale – Over/Under 7.5 Strikeouts (-135/+105)
  Chris Sale was rolling in his last game started and accumulated 7 strikeouts.
  Explain: A pitcher who was strong in his last outing may be sharp once again in his next outing.
• Marcell Ozuna – Over/Under 0.5 Hits (-135/+105)
  Marcell Ozuna has primarily hit in the top-half of the batting order this season (93% of the time), but he is projected to hit 6th in the lineup 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.
• It may be wise to expect better results for the Atlanta Braves offense in future games, considering that the leading projection system (THE BAT X) views them as the 5th-unluckiest offense in the league this year.
  Explain: When teams underperform their projected talent level, markets may undervalue them even while they are likely to perform better in the near future.
