New hitting card drop featuring Anthony Volpe🔥👀

This layout shows how small tweaks in mechanics, bat path & contact point can unlock real gains in ball flight + contact quality.

A clean, connected system built for player development✅📈📊

Jackson Holliday’s talent is obvious. The foundation is there. He has good moves, solid swing decisions and real feel for the zone.

With focused bat speed work and mechanical cleanup this offseason, he’s positioned to make a real jump🔥‼️

Nick Kurtz lived up to the hype…AL ROY and an elite 2025 performer🔥‼️

Here’s a full offensive breakdown and what he should hone in on this offseason: power is there, now it’s about refining his path + reducing swing & miss through targeted training environments👀

Check out this James Wood Hitting Performance Profile🔥👊🏻

This breakdown includes swing decisions, bat speed, contact quality, ball flight, bath path and mechanics👀

This new card layout is perfect for any hitting department looking to up their game✅

#Nationals

[Mikey Corsillo @Corsillo11]

Joey Ortiz is one mechanical adjustment away from becoming a completely different hitter‼️

He’s already a legit defensive weapon.

If he cleans up posture, contact point, and separation at the plate?

He becomes a real problem on both sides of the ball🔥

New card drop✅⬇️

Put together a full 2025 offensive breakdown on Gavin Lux: swing decisions, bat path, ball flight, mechanical notes, and a full drill plan🔥👀

Deep dive on where he wins, where he can level up, and what his offseason focus should be. #Reds

1st hitting development card…✅

[Mikey Corsillo @Corsillo11]

Excited to see where the Guardians No. 17 prospect goes from here. 

The swing is in a really good spot and feels close to unlocking some serious potential that could make him an immediate impact bat at the big-league level.

Offseason programming⬇️

Offset open angle machine (FBs up):

• Offset open
• Pivot picks
• Hookem
• Combine both

Focus: build proper load/coil and a flatter entry into the zone.

Sliders down (back foot):

• Step behind
• Step behind + flow drill

Focus: establish correct pelvic forward bend during the load phase.

Closed angle fastballs (mix high/low):

• Hookem
• Papis
• Hookem + Papis
• Papi + Pivot pick

Focus: get open, avoid diving toward home plate, and refine top-to-bottom posture.

🚨Petey Halpin Swing Breakdown🚨

Halpin’s setup and sequencing present some clear development opportunities heading into this offseason. 

Here’s a deep dive into the biomechanics and how they impact his overall adjustability and bat path.

[Mikey Corsillo @Corsillo11]

This is one of the first things I evaluate in a hitter and is one of the easiest swing movements to link to ball flight👀✈️

Recognize flaws early and program accordingly🔥

External cues are a simple, effective way to teach the body how to move toward the desired outcome relative to the hitters’ posture‼️

[Mikey Corsillo @Corsillo11]

Contact Point

5.6 in. in front of plate (MLB avg 2.9 in.)

32.7 in. from center of mass (MLB avg 30.7 in.)

Catches the ball more out front relative to both the front of the plate and his center of mass (more out front relative to the MLB average as well)📌

4/12

[Mikey Corsillo @Corsillo11]

Bat Path

Attack angle: 9° (MLB avg 10°)

Horizontal attack: 0° (MLB avg 2° pull side)

Swing tilt: 35° (MLB avg 32°)

Struggles to release the barrel to pull side, partnered with an out in front contact point explains pushy/handsy mechanics.

5/12

[Mikey Corsillo @Corsillo11]

Ball Flight✈️

Straight air: 21.1%

Oppo air: 20.7%

Pull air: 15%

Pull GB: 20.3%

Pull-side avg LA: 4° (low liners/short hoppers)

He hits the ball in the air more than ever since 2023 and the majority of his ball flight lands lower to the pull side of the field❌

6/12

[Mikey Corsillo @Corsillo11]

Swing Decisions

Zone Swing%: 63.4% (MLB avg 67%)

Zone Contact%: 78.4% (MLB avg 82.1%)

Chase%: 26.8% (MLB avg 28.4%)

Whiff%: 27.9% (MLB avg 25%)

-7 run value on fastballs (thrown 60.2% of the time)

This tells us that he is swinging at the right pitches and just not capitalizing on the ones he swings at🤔

Lowest Hanging Fruit

🍓Get open w/ the lower half

🍇Create better hip-shoulder separation

🍊Catch the ball deeper

🍉elevate more consistently pull side with better barrel release

The intent needs to stay high with the bat speed and to do damage early in counts🔥

Additional Implements (for extra feel)

I’d cue him to aim down the right-field line to promote a full barrel release.

Then introduce a long bat to challenge the contact point and stay deep, but still release the barrel in time to drive the ball to the pull side.

If the longer implement starts pushing contact too far out front, switch to a short bat to see how deep he can pull the ball while maintaining space and getting the hips open.
