MLB has games spread throughout the entire day on Saturday, providing gamblers with a plethora of strikeout props to pick from. The best strikeout bets got off to a fast start, with two correct selections on Opening Day. Today's best strikeout bets include an over for David Peterson against the strikeout-prone Pittsburgh Pirates lineup and an under for Reid Detmers against the patient Houston Astros lineup.

Why it matters

Strikeout props are a popular betting market in MLB, and identifying the right pitchers to target can provide an edge for bettors. This article highlights two appealing strikeout bets, one over and one under, that could prove profitable for gamblers on Saturday's MLB slate.

The details

For the over bet, the article highlights David Peterson, a left-handed pitcher for the Mets, who has a favorable matchup against the strikeout-prone Pirates lineup. Peterson has improved his strikeout rate and peripheral stats over the past two seasons, and he has been particularly effective at home. His strikeout prop line of 4.5 is seen as a low bar that he should be able to clear against this Pirates lineup. For the under bet, the article focuses on Reid Detmers, a left-handed pitcher for the Angels, who has a challenging matchup against the patient Astros lineup. Detmers struggled with his control and ERA in his first few seasons as a starter, leading the Angels to use him as a reliever in 2025. While his strikeout rate has been solid, his control issues and the Astros' patient approach at the plate make the under 5.5 strikeouts a compelling play.

  • Peterson got stretched out to 76 pitches in his final start of Spring Training on March 22.
  • Detmers got stretched out to only 66 pitches in Spring Training and pitched four innings or fewer in all of his appearances.

“Given Detmers' previous struggles with his control, Houston's patience could result in the lefty inefficiently piling up pitches.”
