Seattle Mariners vs Los Angeles Angels Prediction – 6/8/2025

The Los Angeles Angels will face off against the Seattle Mariners on June 8, 2025, in an American League West matchup at Angel Stadium. The Angels, currently struggling with a record of 30-33, find themselves below average this season. Meanwhile, the Mariners have shown better form with a 32-31 record, placing them in a more favorable position. However, the Angels did beat the Mariners in their game on Saturday.

On the mound, the Angels will send left-hander Tyler Anderson, who has had a rocky year with a 2-2 record and an ERA of 3.86. Despite this ERA, advanced metrics suggest he may have been a bit lucky, with a 5.13 xFIP indicating a potential regression. His projection for this game suggests he will pitch 5.3 innings, allowing approximately 3.1 earned runs while striking out just 4.5 batters on average, which is below average.

The Mariners will counter with George Kirby, a right-handed pitcher who has struggled to find his rhythm this season, with a dismal 0-3 record and an alarming 8.56 ERA. However, his 4.26 xFIP implies he has been unlucky, and projections suggest he might perform better in this matchup, with an average expected output of 2.7 earned runs over 5.8 innings.

Offensively, the Angels rank 22nd in MLB, while their power remains intact with a 4th-best ranking in home runs. Conversely, the Mariners' offense sits in the middle of the pack at 14th, but they also boast the 6th-best home run total in MLB. Given the respective strengths and weaknesses, this matchup could lean towards the Mariners, but the Angels’ power could provide them with some unexpected fireworks.

Quick Takes Seattle Mariners:

With 7 hitters who share his hand in the opposing team's projected batting order, George Kirby figures to benefit from having the platoon advantage in most plate appearances in today's game.

• Right-handed pitchers perform better against right-handed hitters (and the same for lefties). Having this advantage against a lot of opposing hitters can have a huge impact on whether a pitcher will perform well or struggle on any given day.

Dylan Moore has primarily hit in the back-half of the batting order this year (79% of the time), but he is projected to hit 5th on the lineup card in this matchup.

• 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.

Seattle Mariners hitters collectively place 6th- in MLB for power this year when judging by their 10.2% Barrel%.

• 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.

Quick Takes Los Angeles Angels:

Tyler Anderson's fastball velocity has dropped 1.3 mph this year (88.2 mph) below where it was last year (89.5 mph).

• Velocity is a key component to fastball success in generating strikeouts and preventing runs, so a pitcher whose velocity decreases will likely see worse results.

The Seattle Mariners have just 1 same-handed RP in their bullpen, so Nolan Schanuel has a strong chance of never facing a bullpen mismatch all game.

• Hitters perform worse against pitchers of the same handedness (i.e. righty-vs-righty), and being able to avoid those matchups against the bullpen boosts performance and creates hidden edge.

According to the leading projection system (THE BAT X), Mike Trout ranks as the 11th-best batter in Major League Baseball.

• THE BAT X is a highly sophisticated projection system that accounts for a multitude of factors and regularly tests among the most accurate systems available.
