Yuya Tamawaki – Precision and Persistence on the Mound

Brian Eradus • May 13, 2025

At 32 years old, Yuya Tamawaki continues to rise in the fastpitch ranks as a key pitcher for the Georgian Bay Giants. Returning for another ISC season, Yuya isn’t just focused on controlling the game from the mound—he’s also determined to contribute at the plate and build on his team's past performance.

Early Start and Family Influence

Yuya’s love for fastpitch was born early. “I started playing when I was eight,” he says, “because my father played softball. He inspired me to get into the sport and pursue it seriously.” That early family connection helped lay the foundation for a disciplined and focused athlete.

Yuya’s biggest mentor? Former national pitcher Nobunori Nishimura, whose influence helped Yuya develop both technically and mentally.

The ISC Experience

Yuya first competed in the ISC World Tournament last year and described the experience as unforgettable. “The speed of the game and the intensity—it’s something you don’t get even in baseball,” he says. “It was an honor to compete against top players from around the world.”

For ISC newcomers, Yuya offers thoughtful advice:


“It’s okay to feel nervous, but try to relax. When you're enjoying the moment, you'll often perform your best.”


One of his most memorable ISC moments came simply from being on the field with elite talent from across the globe. “It was eye-opening to see the level of play up close.”

Goals for 2025

Heading into the 2025 season, Yuya is focused on improving his all-around game.
“My goal is to win more than last time and to contribute not just as a pitcher, but at the plate too.”

He also understands the small details that make a big difference in high-stakes games. “I’m working on control, speed, and range of motion, and focusing on keeping the leadoff hitter in check—because that can shift the entire game,” he notes.

For the Georgian Bay Giants, the mission is clear:


“Achieve better results than last season, make the most of scoring opportunities, and keep runs allowed to a minimum.”


Training and Mental Preparation

Yuya’s training plan is simple but effective:

  • Pitching reps focused on control and accuracy
  • Strength and mobility exercises
  • Mental prep through visualization and staying calm under pressure

One of the best pieces of advice he’s received came from fellow Japanese national players:


“Improvement comes through consistent effort. Don’t try to be perfect—try to be better.”


Life Outside the Diamond

Off the field, Yuya enjoys fishing and watching sports, which allow him to decompress and maintain balance. He works in electrical

maintenance in Aichi, Japan, and brings that same focus and work ethic to his job as he does to softball.


Looking Ahead

Yuya sees fastpitch not only as a competitive sport but also as a way to build stronger communities.


“Softball can improve communication and contribute to a healthier society,” he says. “It teaches discipline, teamwork, and brings people together.”


As the sport continues to grow worldwide, Yuya believes the ISC can play a key role by showcasing international players, highlighting global journeys, and continuing to provide a platform for teams from every corner of the world.

At 30 years old, Yusef Davis Jr. is entering the 2025 season as a key outfielder for Bear Creek Express , bringing with him a lethal mix of speed, power, and leadership. After playing for San Antonio Glow Worm in 2024, Yusef joins a new chapter with Bear Creek, aiming to be the spark at the top of the lineup—and a threat every time he steps on the basepaths. Late Start, Fast Rise Yusef’s journey into fastpitch began later than most. “I started in late 2015,” he says. “My dad got me into a league in Whittier, California, and I took a liking to it right away.” The intensity, speed, and chess-like quality of fastpitch instantly hooked him. Growing up in Long Beach, CA, Yusef looked up to fastpitch veterans like Kevin Castillo and Lumar Goss , both of whom inspired him through their leadership and talent. "They’ve helped mold me into the player I am today,” he explains. Overcoming Early Challenges Transitioning from baseball to fastpitch wasn’t easy. “Hitting consistently was tough—especially against guys like Folkard , Cleary , and Kirkpatrick . I started out as a slapper just to make contact, then adjusted over time.” He credits those challenges with shaping his current approach: “Now, it’s all about getting on base and causing problems. My goal this season is consistency—be a spark plug and produce every game.”
