Ubaldo Jiménez (born January 22, 1984 in Nagua, Dominican Republic) is a former Major League Baseball pitcher whose career left a strong mark on the game. Known for his blazing fastball, sharp breaking pitches, and calm presence on the mound, Jiménez pitched in the majors from 2006 to 2017, facing the best hitters in the world for more than a decade.

He made history with the Colorado Rockies by throwing the very first no-hitter in franchise history on April 17, 2010. That same year, he was named an MLB All-Star and earned the honor of starting the All-Star Game for the National League. Over his career, he played for the Rockies, Cleveland Indians, and Baltimore Orioles, collecting 114 wins, more than 1,700 strikeouts, and countless memorable outings.

Beyond the numbers, Jiménez built a reputation as a true student of the game. His deep knowledge of pitching mechanics, preparation, and mental toughness made him a respected teammate and mentor in every clubhouse he joined. Even after his final professional appearance in 2020, he has continued to share his passion for pitching, drawing from his vast experience at the very highest level.

As a proud Dominican player, Jiménez has always been part of a close-knit community of fellow countrymen in Major League Baseball—many of whom remain active stars today. His career journey connects him not only to the past and present of the game, but also to its future.
