Team Analysis

Los Angeles Angels

The Angels’ 2-3 mark over their last five games reflects inconsistency, but their 5.2 runs per game during that span indicates the offense is still producing. Jo Adell’s power presence has been critical in keeping scoring afloat when the team’s lineup has otherwise been uneven. On the road, their 32-41 record shows challenges, yet the ability to push runs across consistently gives them a live underdog profile.

Looking at the longer 10-game stretch, a 4-6 record shows they have struggled to string together wins, but averaging 4.5 runs in that span keeps them competitive. Taylor Ward has been a steady run producer, and Zach Neto adds balance to the order, which helps neutralize Seattle Mariners’ pitching edge. The Angels’ offensive depth makes them a viable side to back, especially given the Mariners’ tendency to allow scoring spikes in divisional play.

  • OBP: 0.304
  • SLG: 0.402

  • WHIP: 1.43

Away Record: 32-41 • Home Record: 37-38
Last 5 Games: 2-3 (5.2 RPG)
Last 10 Games: 4-6 (4.5 RPG)


Seattle Mariners

The Mariners have surged with a 5-0 record in their last five, averaging 4.4 runs per game, showing they are winning with balance rather than overwhelming offense. Cal Raleigh’s home run production has been the centerpiece, and his ability to change games with one swing is a constant threat. At home, their 46-27 record demonstrates confidence at this venue, but their scoring average sits in a range that leaves them vulnerable to higher-output opponents.

Over the last 10 games, Seattle is 7-3 while averaging 6.0 runs, highlighting an uptick in recent scoring efficiency. Eugenio Suarez adds another dangerous power source, and Julio Rodriguez’s consistent production rounds out the top of the order. Still, with the Angels’ lineup showing a higher short-term scoring pace, Seattle Mariners’ edge in wins does not erase the potential for Los Angeles to grab value in this matchup.

  • Batting Average: 0.243
  • Total Runs Scored: 687

  • OBP: 0.319
  • SLG: 0.414

Seattle Mariners’ last 10 games have averaged 9.7 combined runs, with 6 games clearing the same number of 7.5.

Moneyline Betting Prediction

The Angels’ higher recent run production compared to Seattle provides a tangible edge, especially given their ability to keep contests tight in recent head-to-head meetings. With Jo Adell and Taylor Ward driving consistent offense, Los Angeles has the firepower to outscore a Mariners team that has leaned on timely pitching, making the Angels the sharper side.

Trend and context support the Los Angeles Angels at +175 as the bet.

Over/Under Prediction

Recent five-game scoring: the Seattle Mariners are at 4.4 RPG and the Los Angeles Angels at 5.2 — a useful baseline against the total.

These teams are combining for 9.6 runs per game recently — above the posted total of 7.5. That points toward the Over 7.5.
