Seattle Mariners

As the Seattle Mariners host the Colorado Rockies at T-Mobile Park on September 25, 2025, both teams find themselves in contrasting positions. The Mariners sit with a solid record of 89-69, looking to bolster their postseason aspirations. In stark contrast, the Rockies have struggled mightily this season, languishing at 43-115. Yesterday, the Mariners continued their dominance, easily dispatching the Rockies 9-2.

For this game, the Mariners are projected to start Emerson Hancock, who’s had a tough year. While his record stands at 4-5 with a 5.13 ERA, he has shown flashes of potential. Hancock projects to pitch 4.7 innings with 1.7 earned runs allowed, despite struggling with a high walk rate. Interestingly, he faces a Rockies lineup that has the 2nd most strikeouts in MLB, which could work to his advantage, considering his low strikeout rate of 15.4%.

On the mound for the Rockies is Bradley Blalock, who has faced his share of challenges. With a dismal ERA of 9.16 and a 2-5 record, Blalock projects similarly to Hancock, averaging 4.7 innings but with a higher earned run projection of 2.9. His peripherals suggest some bad luck, but his low strikeout rate and concerning metrics indicate more struggles ahead.

Offensively, the Mariners boast a potent lineup, ranking 10th in MLB, highlighted by their impressive power, sitting at 2nd in home runs. Meanwhile, Colorado’s offense has been a disappointment, ranking 27th in the league overall. With a low game total of 7.5 runs anticipated, Seattle’s ability to capitalize on their offensive strengths against a struggling pitcher like Blalock could be pivotal for bettors leaning towards the Mariners. With heavy odds favoring Seattle, they appear primed to secure another victory against the reeling Rockies.

Colorado Rockies Insights

• Bradley Blalock – Over/Under 3.5 Strikeouts (+105/-135)
  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 (-170/+130)
  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 10th-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
  The leading projection system (THE BAT X) expects Emerson Hancock to have a pitch count today, projecting a maximum of 78 pitches.
  Explain: A pitcher who is on a pitch count is likely to be pulled from the game earlier, record fewer outs, and generate fewer strikeouts.
• Eugenio Suarez – Over/Under 0.5 Hits (-190/+145)
  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 (-120/-110)
  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.
