Carlos Castillo
Born in Boston, raised in Miami, drafted in the third round by the Chicago White Sox in 1994. Carlos Castillo spent 18 years pitching professionally — four in the Major Leagues, the rest across the minors, Japan's NPB, Taiwan's CPBL, and winter ball in the Dominican Republic, Puerto Rico, and Venezuela. Today he runs Kachi Baseball, a Miami-based academy, and co-founds Kachi Gloves alongside former MLB pitcher Julio Teherán.
The Pitcher
Carlos signed with the White Sox out of Southwest Miami High School in the 1994 MLB Amateur Draft (third round, June 4, 1994). He made his Major League debut on April 2, 1997 at Toronto, age 21, pitching out of the White Sox bullpen for four seasons before moving to the Boston Red Sox organization in 2000. His final MLB appearance came in a Boston uniform on July 22, 2001.
MLB career (1997–2001): 10–7, 5.04 ERA, 111 games, 210⅔ innings, 130 strikeouts. His best year was 1998 — a 54-game workhorse season in long relief for a transitional White Sox team. He pitched at 6'2", 240 lbs, right-handed, wearing #43 in his last Red Sox camp.

The 18 Years
The "18 years" isn't marketing math. It's the literal span from his 1994 draft signing to his retirement from professional baseball in 2011. Between the White Sox and Red Sox MLB stretches, Carlos pitched for the Fukuoka Daiei Hawks in Japan's NPB, the Macoto Cobras and Brother Elephants in Taiwan's CPBL, and in winter ball leagues across the Caribbean. He finished his playing career as a pitching coach for the South Louisiana Pipeliners of the independent Continental Baseball League in 2009, then played two more seasons before hanging up the glove.
That international career is why Kachi's Japanese Kip leather sourcing isn't a marketing story. Carlos spent seasons in Japanese and Taiwanese clubhouses where that material was the professional standard. The choice is personal, not commercial. Read the full Kip vs steerhide breakdown.
Kachi Baseball — The Miami Academy
After retiring in 2011, Carlos came back to South Florida and opened Kachi Baseball, a premier youth baseball and softball training academy in Miami. The academy operates a batting cages and strength facility at 18732 SW 105th Ave, Miami, FL and has become one of the most respected player-development programs in the region. Beyond training, Carlos and his team have built an international pipeline — Kachi International — connecting Latin American talent to US college programs and pro scouts.
The gloves were born here. Carlos started sourcing pro-grade equipment directly from Japanese manufacturers for his academy players because the commercial retail options didn't meet the standard he learned in Asian leagues. Demand grew. Kachi Gloves is what that side project became.
The Teherán Connection
In the 2021 offseason, former Atlanta Braves ace Julio Teherán came to Miami to train with Carlos. Carlos advised him to lower his arm angle, change his changeup grip, and add a cutter — technical adjustments made by a pitcher who spent 18 years learning every way a ball can move. The working relationship continued through Julio's later MLB stops, his 2025 World Baseball Classic qualifier, and his final 2026 WBC appearance.
When Julio retired in March 2026, the partnership with Carlos was already years old. Kachi Gloves is the formal continuation.
