Who will win Angels vs Mariners today: Mariners -1.5 (-103)
The Los Angeles Angels hand Ryan Johnson the ball tonight. He’s only made two starts since being recalled, but opponents have still managed a 40.8% hard-hit rate while Johnson has allowed 1.64 home runs per nine innings. That’s a dangerous combination against a Seattle Mariners lineup that sees the ball better at home.
George Kirby, meanwhile, has been lights out. Over his last four outings, the right-hander owns a 2.82 FIP while allowing just 0.82 home runs per nine innings. Kirby also sports a solid 3.79 FIP at T-Mobile Park this season.
I’ll play this pick to -130.
COVERS INTEL: Seattle’s offense has compiled a 109 wRC+ at home compared to just 94 on the road.Angels vs Mariners Over/Under pick: Under 7.5 runs (-103)
While Ryan Johnson has been vulnerable, Seattle’s offense hasn’t exactly been rolling either, carrying just a .290 wOBA over the last week. That should help keep this total in check, even if the Mariners find some early success against the Angels’ starter.
Both bullpens have also been outstanding lately. Los Angeles owns a phenomenal 1.24 FIP across its last 26 1/3 innings, while Seattle’s relief corps has posted a 2.33 FIP over the past week. Both units have done an excellent job limiting damage late in games.
I expect Seattle to score enough to win behind George Kirby, but runs could be difficult to come by after the starters exit.
I’ll play this to -120.
- ML/RL bets: 31-27, +1.65 units
- Over/Under bets: 32-25, +2.53 units
Angels vs Mariners weather
Conditions at T-Mobile Park should have little impact on tonight’s matchup. Temperatures around 70°F with light 8.1 mph winds create a fairly neutral environment, offering minimal assistance to either hitters or pitchers. The game is more likely to be decided by the starting pitching and bullpen matchups than by the weather.
