Seattle Mariners

On September 12, 2025, the Seattle Mariners will host the Los Angeles Angels at T-Mobile Park for the second game of their series. The Mariners, currently sitting at 79-68, are enjoying an above-average season, while the Angels, at 69-78, find themselves performing below expectations. The Mariners won the last matchup between these two teams by a narrow 7-6 margin, showcasing their offensive power, which ranks 3rd in MLB for home runs this season.

Luis Castillo is projected to take the mound for Seattle. Although his Power Rankings position sits at 100th among starting pitchers, he is having a solid year with a 3.85 ERA and a respectable strikeout rate of 7.0 batters per game. In his last outing on September 7, he went 6 innings, allowing just 1 earned run and striking out 6, a performance that bodes well for today’s game. Conversely, Yusei Kikuchi is slated to pitch for the Angels. His struggles have been evident this season, holding a below-average ranking and coming off a disastrous performance where he allowed 7 earned runs in just 2 innings against the Mariners.

While both bullpens rank as average, the Mariners have the advantage with their offense, which also excels in stolen bases, ranking 4th in MLB. The Angels, despite their power ranking 5th in home runs, have faltered overall, reflected in their 22nd ranking in team offense.

The betting lines reflect this disparity, with Seattle favored at -180, implying a team total of 4.25 runs, while the Angels come in as underdogs with a low total of 3.25 runs. Given the current projections and the recent form of both teams, the Mariners are positioned as strong favorites in this matchup.

Los Angeles Angels Insights

• Yusei Kikuchi – Over/Under 15.5 Pitching Outs (-110/-120)
  Compared to the average pitcher, Yusei Kikuchi has been granted more leash than the average pitcher this year, throwing an extra 6.4 adjusted pitches each start.
  Explain: Pitchers with a longer leash are more likely to go deeper into games and record more outs.
• Chris Taylor – Over/Under 0.5 Hits (-135/+105)
  Chris Taylor is penciled in 2nd in the batting order in this matchup, which would be an upgrade from his 86% rate of hitting in the bottom-half of the lineup this year.
  Explain: The higher in the order a player bats, the more plate appearances he will get and the more opportunities he will get to hit the Over for every market. A player who hits higher in the order than he normally does may provide extra value opportunity since the market may be based on him hitting lower.
• Yoan Moncada – Over/Under 0.5 Total Bases (-160/+125)
  Yoan Moncada pulls many of his flyballs (34.7% — 86th percentile) and is a great match for the park considering he’ll be hitting them towards MLB’s 4th-shallowest RF fences in today’s matchup.
  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.

Seattle Mariners Insights

• Luis Castillo – Over/Under 6.5 Strikeouts (-145/+110)
  Luis Castillo’s higher usage rate of his fastball this season (68.7 compared to 63.4% last year) is not ideal since they are generally much less effective than breaking or off-speed pitches.
  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.
• Cal Raleigh – Over/Under 1.5 Total Bases (+110/-145)
  Cal Raleigh has seen a big gain in his exit velocity on flyballs this season; just compare his 97.4-mph average to last season’s 94.9-mph average.
  Explain: Most home runs are flyballs, and the harder those flyballs are hit, the more often they turn into home runs. This is a strong indicator of power.
• The Seattle Mariners have 3 bats in their projected offense today with a high (i.e. over 27%) underlying K% (per the leading projection system, THE BAT X) (Eugenio Suarez, Cal Raleigh, Luke Raley).
  Explain: Teams that have multiple high-strikeout hitters will make it much easier for the opposing pitcher to record strikeouts
