Today's Strikeout Prop Dashboard

Here are the starting pitchers I'll be targeting for strikeout props on Saturday, April 4, 2026.

Elite K Upside: High-Confidence Strikeout Picks 

Jesus Luzardo OVER 6.5 strikeouts (-103 DraftKings)

Jesus Luzardo got roughed up a bit in his first start against the Texas Rangers, allowing six earned runs across six innings pitched; however, he did manage to strike out seven batters in this game, and he has an even more tantalizing matchup against the Colorado Rockies today.

In the early season, the Rockies are striking out at a 43% clip against left-handed pitchers, which ranks third-worst in the league. I will admit that this is a small sample size, given that the Rockies have just 28 plate appearances against lefties, but their prowess for striking out is well-known. Last season, they ranked second-worst in all of baseball with a K rate near 27% for the entire season.

Luzardo, meanwhile, posted a 30.8% whiff rate last season and paired that with a 28.5% K rate, both of which ranked him in the 86th percentile or better. I will also point out that he has a near a 40% K rate across the 26 plate appearances he has against this Rockies lineup, so he does have some success, albeit in another small sample size.

Emerson Hancock OVER  4.5 strikeouts (-124 NOVIG)

Emerson Hancock might be my favorite play on the slate at OVER 4.5 strikeouts. He was absolutely dominant against my Cleveland Guardians in his first start of the season, striking out a whopping nine batters across six innings pitched while allowing no earned runs.

Cleveland did not strike out a ton in 2025, so this start was especially impressive. He generated a ton of swing and misses (43%) on his sweeper, which could be a weapon moving forward. He also generated a whiff rate north of 24% on his fastball.

Today, he will be up against the Los Angeles Angels, who are known for having a propensity for striking out. Thus far in 2026, they are posting a K rate of of 28% versus right-handed pitching across a total of 254 plate appearances, so we are not talking a small sample size with this matchup.

This K rate is bad enough to rank the Angels seventh-worst in the league. I think we get another strong outing from Hancock in this matchup, and may even take a look at his odds to go OVER 5.5 strikeouts at plus money.

Value Plays & "Under" Targets

 Connelly Early OVER 5.5  strikeouts (+119 DraftKings)

I will admit that I am not usually one to attack the Padres when it comes to striking out, but I am willing to give Early a go in this matchup today, given the value we are seeing on his number.

Early looked great in his debut, striking out six Reds over 5 1/3 innings pitched while allowing no earned runs. He earned a 60% whiff rate on his slider, which he used nearly 17% of the time, and should be able to generate some swing and miss against a Padres team that is not their usual selves just yet this early in the season.

So far, San Diego is posting a 23% K rate against southpaws, which is high enough for me to consider Early here at plus money. Additionally, they are struggling to hit the ball, as noted by their wRC+ of just 49, which ranks fifth-worst in the league. This should help give him a bit of length as well.

Shane Baz OVER 5.5 strikeouts (-124 DraftKings)

I was on Shane Baz in his first start of the season and did not come away so lucky, as he only managed to strike out four Minnesota Twins across 5 1/3 innings pitched while allowing four earned runs. It was an awful start to the season for Baz, but he has a great chance to right the ship in today's start against the Pittsburgh Pirates.

This season, Pittsburgh is posting a 27.5% K rate versus right-handed pitching across a total of 171 plate appearances, which ranks them 10th-worst in the league. Additionally, their wRC+ mark of 101 is just around league average, whereas the Twins are near the top of the league with a mark of 134. The point being that I think Baz could get knocked around much less in this game, and allow him to achieve his number.

Baz's top putaway pitch in 2025 was his knuckle curve, and while he generated a whopping 40% whiff rate with that pitch against Minnesota, he only put away hitters at a 16.7% clip compared to a 26.8% clip last season. These stats do not line up, and I would expect Baz to have a bit more success with it in this matchup.

The "Strikeout Sleeper(s)" of the Day

Randy Vasquez OVER  3.5 strikeouts (-135 DraftKings)

The slate is rather ugly today, to be quite honest, so I am digging a bit deeper into some players I would not normally be looking into for strikeouts, and Randy Vasquez fits that bill. That being said, he looked great in his 2026 debut, striking out eight Detroit Tigers across six innings pitched while allowing just two hits and no earned runs.

The eight strikeouts were very high for Vasquez, and he used his four-seamer and cutter primarily in that start, both of which generated a ton of swing and miss out of Detroit. While I cannot say for sure whether that was due to his pitches or Detroit's cold bats, I can say that the spin rate on his cutter is up 10% from last season, which certainly cannot hurt.

The matchup today against the Boston Red Sox is solid from a strikeout standpoint. Thus far, the Red Sox are posting a 30.8% K rate versus right-handed pitching, which ranks them third-worst in baseball to begin the season. This comes across 214 plate appearances, which is not a small sample. They are also posting just a 93 wRC+ mark over the same sample, which tells me Vasquez could get some length, but you never know when those Red Sox bats are going to break out, especially at home.

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!
