James Karinchak is ready to be in an MLB Bullpen. Last night, he punched out the side with no hits or walks in one inning of work. He sat 95.5 mph with the heater, topping 96. The Curveball was a true 12-6 hammer at 84 mph, getting 25” of IVB difference from his Fastball, and grading at 116 Stuff+. Be on the look out for Karinchak👀. @GaetaSportsMgt @The_BPCsj @Mike_Adams3 #MLB #XL

Christian Coppola is Developing Baseball’s Underrated Pitcher of the Year. Due to just missing the innings number to qualify for national leaderboards, you won’t see his name around too much, but Coppola was dominate all season long. He capped off his Senior campaign with 4.1 no hit innings and 7 Ks this past weekend. The stats speak for themselves, Coppola was striking out 45% of batters he faced. He has two legit plus MLB breaking balls, and will be a very interesting pick up come draft season. Congratulations to Christian on an outstanding season! @christiancppla @SJUHawks_Base @SJUBaseballData

Here’s a @Michael_24lane bullpen from the offseason. RARELY do you find a fastball like this. 93-95 mph, sub 5’ release, 20”+ of carry with >6.5’ extension. This is about as plus of a pitch as you will see in college. Lane also throws 5 high quality offspeed pitches for strikes. A ton of innings this year, a MUST pickup!! #TransferPortal #Baseball #Pitching

Alex would make an immediate impact at ANY D1 school in the country. Would be a great pickup for your program, has the stuff to back it up. Runs the fastball up to 94! @The_BPCsj @Mike_Adams3 @seanduff__ @FlatgroundApp #Stuff #Pitching

Chase Dollander away versus home starts this season. Dollander has been dialed in this year, regardless of where the starts are at. However, you can see how much better his stuff is on the road. Let’s analyze: Fastball: he loses about 3.5” of IVB and 2.5” of HB, causing his Stuff+ to drop ever so slightly. He still sits 99 so it works. Whiff rate drops about 4%. Sinker: Big difference here, while it has less IVB at home, he loses about 4.5 inches of HB, causing an 8 point decrease in Stuff+. While still 106 Stuff+, it is not as good as on the road. We see an increase in whiff rate, but a vast drop off on chase rate. Changeup: Here’s the biggest one. Dropping from 104 Stuff+ on the road to 93 Stuff+ at home due to a loss of horizontal break. This is further represented in a 10% decrease in Whiff rate and a 30% decrease in chase rate. The Slider is elite regardless of the stadium, but the curveball takes a significant hit at Coors Field. Coors Field is not pitcher friendly, and it is extremely interesting to see how everything plays out at elevation. #MLB #Rockies #Baseball

In-Zone Whiff% leaders so far for the 2026 MLB season (>= 300 pitches so far). These 5 starters have been dialed in to start the year. #MLB #Pitching #Baseball

Why is Munetaka Murakami mashing baseballs? While this isn’t the complete reason, often people fail to realize the dissimilarities between baseballs used in the MLB versus the NPB. Balls used in the NPB are smaller, tackier, and have higher seams. All 3 of these factors allow pitchers to spin the ball faster, generating more movement. It is estimated that a pitcher loses around 1.7” of IVB on their fastball from NPB ball to MLB ball. How does this relate to Murakami? Murakami is used to facing fastballs with higher carry, making it easier to adjust to the fastballs in the MLB, even if the velocity might be increased. Think of it like a fastball in Seattle versus a fastball in Denver. I would expect him to continue the trend of hitting bombs this year👀 #MLB #NPB #Baseball #Hitting
