Speed Evaluation
Find out where the athlete is today and what they need to improve. This is the recommended first step for every new athlete.
Book an evaluationBaseball speed development
Build speed that shows up in the game.
Greenlight Speed helps youth baseball players develop measurable speed — from first-step acceleration and home-to-first to top-end speed and the 60-yard dash.
It's not what you were born with. It's what you build.

The approach
Baseball needs fast guys.
The 60 matters. But baseball speed is bigger than the 60.
The 60-yard dash is an important measure of speed. It's used at showcases, by coaches, and throughout amateur baseball to evaluate athleticism.
But baseball rarely gives you 60 yards to get fast. The game is won in shorter windows — your first step, your first 10 yards, beating a throw to first, taking an extra base, closing on a ball, or creating separation on the basepaths.
Greenlight develops speed that shows up in the game — and shows up when athletes are tested.
Event 01
First step
How quickly can the athlete initiate movement and create acceleration?
Event 02
Game speed
How does that speed show up in baseball? Home-to-first is a key timed measure — plus stealing bases, first-to-third, and defensive range.
Event 03
Showcase speed
How does speed perform when it's tested? 10- and 30-yard splits and the 60-yard dash.
We'll help athletes test faster. But the goal is to build a faster baseball player.
How it works
Measured, not guessed.
Evaluate
Understand the athlete's current speed profile. We look at acceleration, mechanics, relevant splits and performance measures, and identify the biggest opportunities for improvement.
Program
Turn what we learn into the right training approach. Sometimes that's individualized; sometimes it's a Greenlight-designed group program or structured speed session.
Train
Coach the work: sprint mechanics, acceleration, speed development, strength and power qualities where appropriate, and the ability to express speed in baseball.
Measure
Put the stopwatch or timing system back on the athlete. Track objective progress, see what's changing, and use it to inform the next block of training.

Exercise PhysiologistSharlyne Rivera
Sharlyne is an exercise physiologist with a background as a collegiate middle-distance runner and graduate assistant coach at UCF. She currently works with Pure Athletics, supporting professional track and field athletes through nutrition and supplementation. She brings a broad understanding of physiology, running, athlete development, and the high-performance track environment to Greenlight Speed.
Co-Founder / Speed CoachEmilio Rivera
Emilio competed as a high-level sprinter, including training and competing with Star Athletics, and became a national champion in 2006. He brings firsthand experience with sprint training and performance and applies those principles within the specific context and demands of youth baseball.
Why Greenlight exists
Together, Sharlyne and Emilio combine exercise physiology, running and sprint experience, coaching, and firsthand experience as parents in youth baseball. Greenlight Speed grew from a gap they saw firsthand: speed matters enormously in baseball, yet dedicated speed development is often missing or lacks baseball-specific context.
Our goal is to bring proven principles of speed development into baseball in a way that is measurable, age-appropriate, and specific to how speed actually shows up in the game.
