Velocity sits at the center of the baseball universe these days. Elite pitching prospects train to throw 95 in high school, and hitters work to maximize exit velocities in an effort to smoke balls into gaps and over fences.In 21st century baseball, velocity is king.But against the current Kansas City Royals lineup, velocity isn't kingly at all. It's more like the court jester at best. It's not velocity that gives Royals hitters night terrors, it's a lack of velocity.The soft to sers, as they are commonly known, have routinely gotten the best of the Boys in Blue this season. The subject came up when my co-host and I were previewing the Rays series during . We focused for a moment on . My curiosity piqued, I decided to dive San Francisco 49ers Jersey into some numbers.To scratch my brain itch, I developed a list of opposing pitchers who have thrown 10 or more fastballs at 91 mph or lower, Garrett Celek Jersey be they four-seam, two-seam, cutter, or sinker. I call this group the "soft to sers." Then, I did the same for pitchers who have thrown 10 or more fastballs at 95 mph or higher. I call them "power pitchers.My digging yielded 18 soft to sers and 33 power pitchers. From there, I searched for data on how the Royals have fared against each group.It's not universal, but the results are pretty clear. The Royals prefer spicy to mild.Scroll to ContinueFive of the six hitters with the most plate appearances for the Royals have lower against the soft to sers than the power pitchers, including large differences for Salvador Perez, Jorge Soler and Andrew Benintendi.Difference in offensive output between soft to sers and power pitchers (soft to sers offensive numbers-power pitchers offensive numbers)PlayerBA_DIFFSLG_DIFFOBP_DIFFWOBA_DIFFMerrifield, Whit-.035.04-.035-.002Santana, Carlos.098.077.048.053Perez, Salvador-.079-.116-.054-.065Soler, Jorge.013-.001-.127-.084Benintendi, Andrew-.096-.170-.110-.116Lopez, Nicky-.061-.177.047-.022Taylor, Michael A..135.161.140.128Dozier, Hunter-.05-.075-.105-.083Alberto, Hanser.028.079.066.070O'Hearn, Ryan-.043.175-.014.057Perez and Soler fit fairly neatly into a narrative that explains why they struggle more with soft to sers than power pitchers. Both are mashers who rely on big leg kicks and timing fastballs to hit home runs. Soft to sers can me s with their timing and entice them to swing at breaking pitches and slow fastballs outside and on the edges of the zone.Benintendi is a more confusing case. A deeper dive Ahkello Witherspoon Jersey into the numbers may tell us for sure, but I suspect that he has struggled with soft to sers because left-handed pitchers are a larger proportion of the soft to sers than the power pitchers. He's hitting much worse against lefties than righties this season . Also, he's probably had a little bad luck Roger Craig Jersey against the soft to sers with a .235 BABIP.Only two regulars are hitting significantly better against soft to sers than power pitchers (three if you count Kelvin Gutirrez as a regular, which I don't yet): Michael A. Taylor and Carlos Santana. Taylor's dominance against soft to sers is driven primarily by an unsustainable .478 BABIP against them so we'll see if his succe s against soft to sers continues.Santana, on the other hand, is practically the anti-Perez. , it's harder to get him to chase breaking pitches or slow fastballs outside the zone for whiffs and weak contact. It makes sense that he would have more succe s against soft to sers; he forces them to throw him very hittable pitches, which explains his excellent .302/.423/.558 slash line against them.While it can be frustrating to see the Royals struggle against pitchers whose fastballs couldn't knock over a yard sign, the inverse would actually be worse. There are far more power pitchers in today's MLB than there are soft to sers. The soft to ser is a dwindling breed. And the Royals actually followed a similar playbook during their back-to-back World Series runs in 2014 and 2015, as they tore through power pitching in the playoffs. Of course, good teams can mash both, but if your favorite team has to only be good against one, it's better to be good against the power pitchers these days.It's still early in the season, and the sample of soft to sers is still relatively small. But the Royals' struggles against them are worth keeping an eye on. I certainly will. Because, sometimes, it's so baffling Matt Breida Jersey to see I can't look away. I just stare at my television and think to myself, "Read More:
