1. Marcus Stroman's Fastball
With Marcus Stroman, it's always been about the elite movement he gets on his heater, which has him among the best in the game in groundball rates. This pitch didn't get nearly as much love as it deserves this week, acting like a Splitter at 94mph to Tuffy Gosewisch. This ball starts off acting like a meatball Fastball down the heart of the plate before falling off a cliff where Gosewich has zero chance of making contact. Absolutely filthy.
2. Sonny Gray's Slider
After a long hiatus on the DL, Sonny Gray made his fourth start of the season against the Red Sox on Thursday night and showed off the upside we've been waiting to see from Sonny for months. He fanned eight Boston batters across the evening including Hanley Ramirez on this Slider that looks like a strike until the very last moment, diving under the zone. Ramirez's reaction is just too good, showing us how we would all feel trying to hit Gray's super good slide piece.
3. Luis Perdomo's Fastball
Luis Perdomo is turning heads this spring as he's improved his strikeout rate while inducing groundballs at a league leading 70% rate overall. His signature pitch is a 94mph Fastball that features a ton of sink and ride, keeping it down in the zone while often surprising batters with pitches that comeback to the plate with late bite. This pitch above to Nick Franklin is a great exhibition of that ability as the ball changes direction to nip the inside corner at a blistering 96mph.
4. Adam Ottavino's Slider
It's no secret that Adam Ottavino has one of the filthier Sliders in the game and with the Rockies in Minnesota it meant that we got some excellent camera angles to capture its fantastic movement. Watch this pitch start along the outside corner before diving to the perfect spot against Kennys Vargas. There is nothing you can do if you're a lefty slugger here but swing right over the pitch as it dips to your ankles.
5. Corey Knebel's Fastball
It's a week filled with good reactions as this Corey Knebel Fastball gets one of the most satisfying results you'll ever find as a pitcher - a batter falling to his knees trying so hard to connect with your pitch. The location is far from ideal, but blowing 99mph past Allen Cordoba and inducing such a display of failure makes up loop this pitch over and over again.
