The Louisville Bats made history by signing Casey Kelly, son of manager Pat Kelley, marking the first father-son duo in the team's history. Casey, who has had a successful stint with the LG Twins in Korea, where he led in wins and was named an All-Star, will make his U.S. professional debut this Sunday. Meanwhile, David Ortiz Jr., son of the Boston Red Sox legend, has signed with the Texas Rangers for $225,000 and a scholarship, continuing his father's legacy in baseball. Ortiz Jr., 17, follows his brother D’Angelo, who was drafted by the Red Sox earlier this season. The trend of second-generation players in MLB is growing, exemplified by the Ortiz family's involvement. Both players symbolize a new generation of talent in the sport, leveraging familial connections to build their careers.
