Today's Strikeout Prop Dashboard

Here are the starting pitchers I'll be targeting for strikeout props on Saturday, March 28.

Elite K-Upside: High-Confidence Strikeout Picks 

Eury Perez OVER  5.5 strikeouts (-155 Hard Rock)

We are going to kick this full slate Saturday off by attacking the Colorado Rockies, who posted a 26.4% K rate vs. right-handed pitchers in 2025. This was bad enough to rank them second-worst in the league behind only the Angels, and they did not improve much at all heading into this season.

Perez has elite strikeout stuff, as he posted a 28.4% whiff rate and 27,3% K rate in 2025, both of which ranked him in the 74th percentile or better. This is also a rather low number for Perez, as he struck out six or more in 11 of his 20 starts last season, and each of his final four starts.

He has worked himself up in spring training and has eclipsed the 80-pitch mark, so he will be ready for this matchup. Be sure to shop around on this number because there are definitely some 6.5's with plus money out there if you prefer a little more risk and bang for your buck.

Kyle Bradish OVER  5.5 strikeouts (-155 Hard Rock)

Kyle Bradish was awesome in his return in 2025, as he posted a 31.4% whiff rate, 37,3% K rate, and 31.2% chase rate. These amounted to him recording 47 strikeouts across his 32 innings pitched. While he did not qualify in terms of Statcast metrics, he would have ranked very highly in each of these categories.

The fact that we are getting 5.5 on his K prop is quite nice, as most books are sitting at 6.5 with plus money to the over. Last season, he struck out six or more batters in five of his six starts. Today, he gets the Minnesota Twins, who should struggle quite a bit this season and are very likely to finish near the bottom of the AL Central.

In 2025, the Twins posted a K rate of 22.5% against right-handed pitchers, which ranked them in the bottom half of the league. Bradish has worked himself up to north of five innings pitched in spring training this year, and should be ready to handle a solid workload today as well.

Value Plays & "Under" Targets

Sonny Gray OVER  6.5 strikeouts (+120 NOVIG)

Sonny Gray is probably the most risky play on the card today, as you never quite know what type of strikeout performance you will get from him on any given night. That being said, he did post a 26.7% K rate in 2025, which ranked him in the 79th percentile. Additionally, his 31.2% chase rate ranked him in the 81st percentile.

He will be up against the Reds, who posted a 23.4% K rate against right-handers in 2025, which ranked them sixth-worst in the league. Gray also used to pitch for the Reds, so he could have some added motivation to take them down in his Red Sox debut.

Gray made a total of 32 starts for the Cardinals last season and managed to strike out seven or more batters in just 12 of those starts; however, he finished the season strong, striking out at least seven in each of his final three starts. For what it is worth, he has also had success against this Reds' lineup, as he has a 32.6% K rate against them across 95 plate appearances, which is no small sample.

Joey Cantillo OVER 5.5 strikeouts (+105 NOVIG)

I really like the odds we are getting on Cantillo to go over 5.5 over on NOVIG. Cantillo is a strong strikeout arm the Guardians are developing, and we know how well they do with pitchers. In 2025, he posted a 26.9% K rate and 29,7% whiff rate, both of which ranked him in the 79th percentile or better.

Across his 95 1/3 innings pitched, he managed to strike out 108 batters, and he has a solid matchup against the Seattle Mariners this evening. In 2025, Seattle posted a K rate of nearly 25% against left-handed pitching, which ranked them fifth-worst in the league.  Cantillo is another arm that has pitched north of 70 pitches this spring and will be ready to roll for his 2026 debut.

I also want to point out that Cantillo was converted to a starter late in 2025 and managed to rack up six or more strikeouts in five of those 13 starts; however, if you wanted to take him down to 4.5, he achieved this number in 10 of those 12 starts.

The "Strikeout Sleeper" of the Day

David Peterson OVER 4.5 strikeouts (-135 Hard Rock)

David Peterson is not usually known as a high strikeout pitcher, but he is definitely capable of racking up some punchouts. This is noted by his 2025 season debut when he mowed down nine Marlins over six innings pitched. Today, he will be up against the Pittsburgh Pirates, who posted a 25.8% K rate versus southpaws in 2025, good for second-worst in the league.

In addition to the nine-strikeout performance last season, Peterson managed to strike out five or more batters in more than half of his starts. While his K rate is a bit lower than most in this article, he did post a rate north of 20% last season. Additionally, he has nearly a 30% K rate against this Pirates lineup across 75 plate appearances.

How to Bet MLB Strikeout Props 

Example: When betting MLB K props, our process at RotoBaller focuses on three primary pillars:

1. Opponent Strikeout Rate: We target lineups that rank near the bottom for K% against the pitcher's handedness.
2. SwStr% (Swinging Strike Rate): A pitcher’s ability to generate "whiffs" is a better predictor of future strikeouts than their actual K total from the previous game.
3. Volume & Efficiency: A high K/9 doesn't matter if the pitcher is pulled after 75 pitches. We track pitch-count trends to ensure our "Over" picks have the longevity to reach their totals.

Good luck with your bets, and be sure to check back daily for the latest MLB player prop picks!
