Mariners vs Angels Preview
This game triggered one of our Action PRO betting systems, powered by Evan Abrams.
The Series Unders: Off Low-Scoring Games system focuses on regular-season MLB matchups where both teams are entering the second or later game of a series after producing minimal offense in their previous outing.
Saturday's matchup ended with the minimum score — a 1-0 Angels victory over the Mariners.
Friday's contest didn't produce fireworks either, as Seattle won 3-1.
When teams come off one- or two-game streaks of low scoring, particularly early to mid-series, the market can overcorrect or undervalue continued offensive stagnation.
This MLB model anticipates that trend to persist — betting on the under when recent results and situational rhythm point to a slow-paced, low-output environment.
Also, Action PRO projects Luis Castillo for 6.2 strikeouts this afternoon.
The Mariners starter will be the key after an excellent first outing this season against the Yankees, when he allowed just two hits and no runs with seven Ks through six innings.
Pick: Under 9 (+100, DraftKings)
