Noah, a right-handed pitcher, came to me after his freshman year throwing 74–76 mph. Now, he’s up to 83–85. Noah’s a competitor with big dreams and relentless work ethic. He’s super dedicated to pitching—and most importantly, he competes. He denies runs and fights to win. While some get recruited early with big metrics, I’ve seen long-term growth lead to success. Noah’s dedication and competitive fire will bring him that success down the road, and I fully anticipate it.

Colton is the younger brother of Bryce Rainer, but unlike Bryce, Colton wasn’t scouted early on. He was a raw talent who emerged later, dedicating himself to the weight room, which changed his trajectory. After his sophomore year, we worked hand-in-hand, emphasizing strength. He’s put on over 20 pounds, and his velocity jumped from 85 to 93–94 mph. Once unnoticed, he’s now committed to UCLA and is projected as a 2026 draft prospect. His late rise is a testament to his work ethic and the power of physical development.

I met Jack back in 8th grade—a young, talented pitcher who’s developed into a strong arm. Comparable to Spencer Strider, the 5’10” righty and I focused on strength and explosiveness. Though Jack underwent Tommy John surgery, he’s been rehabbing with me for the past 8 months, consistently rebuilding. He’s on track to return to 94–96 mph and will head to Oklahoma State after his senior year. Jack’s resilience and meticulous work will set him up for a bright future.

Chase and I connected back in 8th grade over our shared mentor, Tom House, which deepened our bond beyond baseball. As a right-handed pitcher, Chase attacks the zone relentlessly. Over the past 8 months, he’s added 12 pounds of lean muscle, bringing his velocity from 83–84 to 86–87 mph as he enters his junior year. A strike-thrower, competitor, and all-around great kid, Chase is set for big results this season. I can’t wait to see him dominate college ball and seize his opportunities at the next level.

Brayden is a long-levered, 6’5” left-handed bat with an incredible swing and tireless work ethic. Comparable to Christian Yelich, he’s added 15 pounds this year, now at 190, on track to become a power-hitting force. Whether it’s college baseball or pro ball after high school, his swing, competitiveness, and winning mindset will set him apart. I’m thrilled for Brayden—he’s a great kid with limitless potential in the game.

Robbie is a twitchy athlete who’s added 12 pounds of muscle and now hits for power. He’s consistent in his work, with a swing that plays at a high level. His defense and arm strength make him a force on the field. A competitor who knows how to win, Robbie’s ready for college baseball. I’m excited not just for his potential, but for the growth he’s shown over the past two years—he’s on a great path.

Isaiah is a gifted left-handed hitter, blessed with unmatched twitch and athleticism. At 6’4”, his strength and mobility are elite—he does things in the weight room that even pro athletes rarely do and runs a blistering 6.1-second 60-yard dash. His lefty bat is explosive—he showcased it in the Perfect Game All-American Home Run Derby. Now committed to Oregon, Isaiah is climbing draft boards and looks poised for the 2026 MLB Draft

Andrew is a big, physical left-handed hitter who wanted to capture Division I attention. Despite his size and projectability, early concerns were around speed, swing path, and field play. Through hard work last spring and summer, he made key adjustments. That effort paid off—he caught the eyes of Division I coaches and earned a major offer from Xavier. Now committed, he’ll continue to grow and is on track to develop into a pro prospect for the 2027 MLB Draft.

I met Ethan in his sophomore year. A naturally gifted athlete, Ethan had raw power in both the weight room and on the field. Our focus was refining his skill—his swing, his throwing motion, and building on his incredible foundation. Ethan runs a blazing 6.4-second 60-yard dash. In the weight room, he’s a leader—deadlifting up to 700 pounds, back squatting over 500, and benching over 300. Beyond his numbers, Ethan drives and inspires everyone around him. As he heads to Santa Clara, he’s a prime example of combining raw talent with refined skill.

When I was the JV coach at Thousand Oaks High School in 2021, I met Luke as a tall, lanky freshman pitching against us. I offered him a quick biomechanical tip mid-game, and he immediately struck out three. He started at 77 mph, becoming one of my first trainees. Now, he’s topping out at 97 mph. Whether pro ball or Division I next, Luke will pitch at the game’s highest levels. His dedication to detail is unmatched—he loves the process, and watching him grow from that lanky freshman to a dominant pitcher has been incredible.

When Sammy first came to me in October of his senior year, he was dealing with arm discomfort and had lost some velocity—down from 91 mph to about 87-88 after illness over the summer. We focused on building his strength capacity, improving movement efficiency, and refining his biomechanics through a structured throwing program. By the end of his senior year, he was hitting 94-96 mph. After starting at Stanford, he transitioned through the transfer portal to Duke, where he’s thriving. Beyond baseball, Sammy’s determination and character assure me he’ll succeed in any path he chooses—sport, business, or life. 

I started working with Tyler in his junior year of high school. A brilliant left-handed hitter with great bat-to-ball skills, Tyler balances deep thinking with natural athleticism. Our work has been about letting that athleticism shine—helping him become more twitchy and instinctive, rather than mechanical. Tyler made an immediate impact, playing as a freshman at Harvard, with a strong sophomore season. Now set for his junior year, our focus is on preparing him for a professional career. Tyler is one of the closest athletes to me, and I’m incredibly proud of his growth over these last five years.  

Brady was one of my original Costello Coaching clients, eager to hit showcases for offers. I taught him my model: train until your metrics have value, then showcase. In four months, Brady’s 60-yard time dropped from 7.3 to 6.7. His exit velocity jumped 7 mph, his throwing velocity by 5 mph, and his pop time improved by 0.2 seconds. After eight months of training, he re-entered the showcase world, earning eight Division I offers. Now Oklahoma State’s catcher, Brady is set for a big year, and we’re working toward his professional future behind the plate.

Trevor was one of the first athletes I ever trained. As a sophomore at Royal High School, we focused on a complete transformation—building his body to support strength, power, and inning capacity. With refined biomechanics, he set records at Royal and became UC Irvine’s number one starter. Now on track to be a top draft pick, Trevor’s disciplined process from grassroots to elite is incredible to witness. Seeing him succeed at such a high level is truly rewarding.

There’s no athlete I’m prouder of than my brother, Jack. Overlooked early on—told to be a pitcher only despite his naturally beautiful swing—Jack was determined to chart his own path. He went to the University of San Diego under the radar. After a tough start as a freshman, he came home, putting in 8-10 hours daily. That fortitude led him to crack the starting lineup, become a Freshman All-American, and later excel in the Cape Cod League. Though a broken hand derailed his draft hopes junior year, Jack returned as a senior leader, earned an invite from the Padres, and dominated his pre-draft workout—becoming a 10th-round pick. After a strong pro start, he just finished his first full season in High-A. This offseason, he’s transformed—improving barrel speed by 8 mph, lowering body fat by 4%, and adding 8 pounds of lean mass. Beyond baseball, I’m most proud of his Padres Humanitarian of the Year award—he’s donated to pediatric cancer causes and leads in the community. Jack’s success on and off the field is just getting started. 

Marcus began training with me prior to the draft, driven by an unmatched work ethic. With a high motor and energy, he focused on building strength and power at the plate. We refined his swing mechanics and added size, improving his consistency. Notably, Marcus holds the most workouts logged in my coaching app, embodying commitment to process and execution. Throughout each minor league season, we work hand-in-hand to keep progressing. With his relentless focus, we’re on track to see Marcus break through to the big leagues soon.

Michael joined me during his transfer from the University of Washington to Oklahoma. At Washington, he was a middle-of-the-lineup presence, but at Oklahoma, we honed his leadership qualities. Michael transitioned into a team captain role, leading his squad to a Big 12 championship. Alongside his leadership, we focused on amplifying his power at the plate, building on his strong foundation. This growth propelled him to become a 10th-round MLB draft pick by the Marlins. After a successful first year in the minors, Michael is now in Double-A, continuing to thrive. He’s not only a talented athlete but also a person whose leadership and work ethic will carry him far in the game.

Quentin joined me before his senior year, from a family of big leaguers. While his raw power was unmatched, his junior year saw just one home run. We knew the key wasn’t just physical; it was mental. We built a structured mindset approach—helping him stay disciplined, trust a repeatable plan, and channel confidence in every at-bat. We focused on stability and swing repetition, but the mental shift unlocked his potential. From 1 home run junior year to 14 senior year, he became the 54th overall pick. At the MLB Combine, he set exit velocity records—proof of his hard work. Quentin’s talent was rare, but it was his mindset development—staying focused, trusting the process, and executing under pressure—that transformed him. As he begins his pro career with the Twins, I’m confident his mental approach will carry him far.

I had the privilege of working with Trevor for one offseason. Even as an All-Star, Trevor felt he had lost some velocity and wasn’t sure why. Together, we re-patterned his ground contact mechanics, optimizing how he harnessed force from the ground. This helped him not only find the strike zone more consistently but also reclaim his velocity. Trevor’s mindset was key—despite his success, he was relentless in pursuing his full potential. After a strong season, he’s determined to repeat that success and more.

Bryce came to me after his junior year, already highly ranked. Yet, on the summer circuit, scouts flagged handling velocity at the plate. As a two-way player, we focused on building both his pitching and hitting. From August to January of senior year, Bryce added 14 pounds, transforming his game. He began dominating velocity at the plate and raised his pitching velocity from 93 to 97 mph. His standout senior year led to him being the 11th overall pick by the Tigers. Bryce, whom I consider like a younger brother, is a true leader among peers. His relentless approach to his craft ensures a bright future—an athlete others will aspire to be like.

Jacob came to me before his junior year of college, already an elite talent in fielding, hitting, and baseball IQ. Yet, we knew his biggest draft leverage was improving his speed. As a backup on the USA Collegiate National Team, he was determined to become a first-round pick. We focused on strength development, taking his home-to-first speed from 4.4 to 4.1 seconds. This metric helped secure his first-round selection—6th overall. After that, his mindset was “whatever it takes.” We built substantial strength, adding 15 pounds, boosting his power, and he hit over .400 in the minors, earning his big-league call-up. The next year, he continued his strength journey, finishing second in AL Rookie of the Year. Jacob’s story is one of grit—once overlooked, he forged a path of excellence that led him to the top.
