MLB has games spread out throughout the day on Saturdays, giving gamblers plenty of strikeout props to choose from. With two correct picks, the best strikeout bets got off to a fast start opening day. Both highlighted pitchers hit their overs for strikeouts.
Today’s best strikeout bets include an over and an under. A southpaw has a comfortable matchup against a strikeout-prone lineup at home, making his over a compelling bet. Another lefty has a challenging matchup against a lineup that has multiple hitters and a low strikeout rate against southpaws and some patient hitters who can work on a pitcher’s pitch count, increasing the appeal of betting on his underdog.

Over 4.5 Strikeouts (-130) at Fanatics Sportsbook.
david peterson He had a breakout 2024 season with a 2.90 ERA in 21 starts, but his ERA projections, including a 4.59 xERA, 4.10 xFIP and 4.37 SIERA, suggested he was quite lucky. Predictably, Peterson did not duplicate his sub-3.00 ERA.
The lefty pitched to a 4.22 ERA in 30 starts over 168.2 innings in 2025. Interestingly, his 4.59 xERA in 2025 was identical to his mark in 2024, and he improved his xFIP to 3.72 and his SIERA to 4.09.
Peterson also increased his strikeout rate from 19.8% in 2024 to 20.7% in 2025. They also increased their calls-plus-swinging-strike rate from 27.5% in 2024 to 27.8% in 2025. Peterson is no world-beater, but he is a rock-solid pitcher, and he may be a little better than last year’s ERA suggests.
This 30 year old bowler is very fast even on home ground. In 132 innings on home ground from 2024Peterson has swung a 3.89 ERA, 3.82 xFIP, 1.37 WHIP, 8.9% walk rate and 20.6% strikeout rate.
He should be ready for a near-full workload in his first start of the season. Pietersen got pulled up 76 pitches in his final start of spring training on March 22.
Peterson’s strikeout prop line of 4.5 isn’t particularly high, and he could clean it up in a favorable matchup. Roaster Resources Projects the Pirates to start Oneil Cruz, Brandon Lowe, Bryan Reynolds, Marcell Ozuna, Ryan O’Hearn, Jared Triolo, Jake Mangum, Nick Gonzales and Henry Davis against left-handed starting pitchers.
eight of them projected initiator There have been at least a 20.8% strikeout rate against lefties since 2024, and seven of them have had at least a 22.1% strikeout rate. Five of the projected starters have struck out in more than a quarter of their plate appearances against lefties since 2024.
Pietersen has a dream matchup to bowl out batsmen. He’s a good bet to cross the lower limit of 4.5 strikeouts and strike out at least five Pirates today.

Reed Detmers (Los Angeles Angels – SP)
Under 5.5 Strikeouts (-118) at FanDuel Sportsbook.

The lefty had a good strikeout rate. However, his ERA was ugly, his ERA estimator was ineffective and his control was lousy. As a result, Detmers spent the entire 2025 season as a reliever. It was a good enough outing for the Angels to give Detmers another start.
Detmers lasted only 66 pitches spring training. He pitched four or fewer innings in all of his appearances.
Detmers may struggle to pitch deep enough to exceed 5.5 strikeouts a game today. Furthermore, Detmers has a challenging matchup.
Astros started Last night, Jeremy Pena, Yordan Alvarez, Isaac Paredes, Jose Altuve, Carlos Correa, Cam Smith, Christian Walker, Yanner Diaz and Bryce Matthews faced lefty Yusei Kikuchi. six batsmen among them The strikeout rate against southpaws since 2024 was 19.0% or lower, and four of them had a strikeout rate of 17.4% or lower.
Additionally, three of those hitters had a walk rate of 10.4% or higher. Given Detmers’ past struggles with his control, Houston’s patience could result in the lefty inefficiently fielding pitches. Ultimately, Detmers’ strikeout rate is an ineffective 19.1% in his career Against batters from Houston’s current roster. Therefore, should Detmers log fewer than six strikeouts, that would make his -118 odds at FanDuel Sportsbook for one of Saturday’s most attractive strikeout bets.
