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.
