Seattle Mariners

The Seattle Mariners are set to host the Colorado Rockies on September 25, 2025, in what is shaping up to be a pivotal matchup for the Mariners, who are enjoying a strong season with a record of 89-69. In contrast, the Rockies are struggling mightily at 43-115. After a tough loss in yesterday’s game, the Mariners will be looking to bounce back and solidify their position as they aim for a postseason berth.

Projected starters Emerson Hancock for the Mariners and Bradley Blalock for the Rockies both bring their own challenges to the mound. Hancock, despite being ranked as the 234th best starting pitcher in MLB, has shown flashes of promise, particularly with his ability to limit earned runs, projecting to allow only 1.7 earned runs on average today. His low strikeout rate of 15.4% could be a concern, especially against a Rockies lineup that strikes out frequently, ranking 2nd in MLB for strikeouts.

On the other hand, Blalock, who has struggled with a 9.16 ERA this season, is projected to allow 3.0 earned runs and 2.0 walks on average. His 10.2% strikeout rate suggests he may have a tough time against a Mariners offense that ranks 11th overall and excels in power, sitting 3rd in home runs. The Mariners are expected to score around 4.64 runs today, which reflects their offensive capabilities.

With the Mariners’ playoff hopes hanging in the balance and their bullpen ranked 10th in MLB, they are favored to secure a win today. The Rockies, meanwhile, find themselves with a low implied team total of 3.36 runs, reflecting their struggles at the plate. As the Mariners look to capitalize on their home-field advantage, this matchup could be crucial for their postseason aspirations.

Colorado Rockies Insights

• Bradley Blalock – Over/Under 3.5 Strikeouts (-110/-120)
  Out of all SPs, Bradley Blalock’s fastball spin rate of 2101 rpm grades out in the 12th percentile this year.
  Explain: Spin rate is a key component to fastball success in generating strikeouts and preventing runs.
• Hunter Goodman – Over/Under 0.5 Hits (-180/+140)
  In terms of his batting average, Hunter Goodman has been very fortunate this year. His .277 rate has been significantly inflated relative to the leading projection system (THE BAT X)’s version of Statcast-based Expected Batting Average (xBA) at .225.
  Explain: xBA uses highly advanced Statcast data to measure a player’s batting average ability more accurately than actual batting average can.
• Colorado Rockies – 2H Moneyline
  According to the leading projection system (THE BAT), the Colorado Rockies’ bullpen ranks as the 9th-worst among all the teams in the majors.
  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.

Seattle Mariners Insights

• Emerson Hancock – Over/Under Pitching Outs
  Emerson Hancock has been given a shorter leash than the average pitcher this year, throwing 6.1 fewer adjusted pitches-per-game than average.
  Explain: Pitchers with a shorter leash are more likely to get pulled earlier in games and record fewer outs.
• Eugenio Suarez – Over/Under 0.5 Hits (-195/+150)
  Eugenio Suarez has primarily hit in the top-half of the lineup this season (78% of the time), but he is projected to hit 6th on the lineup card in today’s 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.
• Cal Raleigh – Over/Under 1.5 Total Bases (-115/-115)
  Cal Raleigh pulls a high percentage of his flyballs (43.3% — 100th percentile) and has the good fortune of hitting them towards MLB’s 4th-shallowest RF fences in today’s game.
  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.
