In the language of pitching, the slurve is a study in deception — a hybrid offering that borrows traits from both the slider and the curveball and uses that blend to disrupt a hitter’s timing and eye. The pitch does not travel in a straight line; instead it moves diagonally across the strike zone, combining downward drop with sweeping side-to-side action. That combination of movement can induce swings and misses and force weak contact, a quality that has made the pitch an increasingly valuable tool in a game built on outsmarting batters.

The slurve’s image in baseball has shifted over time. Once dismissed by some as a sloppy hybrid that lacked the distinctiveness of a true slider or a classic 12–6 curveball, it has been reassessed by pitchers and coaches as its own, strategic weapon. When executed well, the pitch is not merely a middling oddity but a deliberately chosen offering that creates awkward visual and mechanical problems for hitters. That reassessment has coincided with teams and pitchers who focus on movement and deception rather than raw velocity, allowing the slurve to flourish in certain arsenals.
For the Arizona Diamondbacks, one of the most visible practitioners of the pitch is Michael Soroka. The 28-year-old right-hander, acquired by the team in the offseason, has reshaped his approach in the years since battling a string of injuries. He now mixes the slurve with four other pitches — a four-seam fastball, a changeup, a sinker and a cutter — deploying the slurve as a go-to breaking offering that helps generate strikeouts. Despite a velocity that sits in the low 80s, Soroka’s slurve has produced a notable whiff rate and has led to a lower batting average against when hitters try to square up on it.

Soroka’s numbers through late May illustrate how often and how effectively he leans on the pitch. He has used the slurve on roughly one-third of his offerings, and that pitch has produced a whiff on a similar proportion of swings. Those are significant figures for a breaking ball that does much of its damage by moving hitters off the plane of the ball and away from their preferred swing paths. The results on the scoreboard have followed: after a May 27 victory over San Francisco, Soroka sat at 7-2 on the season. Even in outings that did not end in a win, his work often featured effective use of the slurve — on May 22 against Colorado he turned in a quality start, allowing one earned run on four hits while recording a pair of strikeouts.
Teammates and observers have noticed the difference Soroka’s arsenal has made. He drew praise when he contributed to a 6-3 win over Toronto in mid-April, and those kinds of performances underscore how the slurve can serve both as a put-away pitch for strikeouts and as a pitch that weakens contact when batters do connect. The broader Diamondbacks staff has also leaned into breaking offerings as a means of producing swings and misses, and Soroka’s slurve fits into that team-wide emphasis on movement and deception rather than relying exclusively on high velocity.
Technically, the slurve occupies a middle ground in repertoire construction. By sitting alongside a four-seam fastball, sinker, cutter and changeup, it gives Soroka a contrasting look that can mask the pitch’s release and trajectory. The slower, sweeping action of the slurve — even at a modest speed compared with power fastballs — calls on the hitter to adjust timing and plane, and when paired with faster, straighter pitches it creates uncomfortable sequencing for opposing lineups. That strategic value is the reason the pitch, once written off by some, has been rehabilitated and embraced in certain contexts, including by this Diamondbacks starter.
Soroka’s personal comeback arc has been shaped by injury and adaptation, and the slurve represents one piece of that reinvention. While the pitch does not boast elite velocity, its movement and Soroka’s willingness to use it often have helped him generate missed swings and limit damage. For a club that has prioritized breaking offerings and for a pitcher rebuilding his career, the slurve has become a signature pitch that combines historical skepticism with modern effectiveness. The result has been a practical weapon in Soroka’s toolbox and a noticeable component of Arizona’s pitching approach this season.
