MLB Player Agent - Lagardere Sports
"I’ve known Seth for 35 years — as an opponent, client, advisor, and friend. He brings unmatched work ethic, outstanding organizational and leadership skills, and a sharp eye for talent. His integrity and character set him apart!
Seth’s resume is truly extraordinary. Drawing on his vast experience, Seth provides unique insights at every stage of the game — whether guiding players toward college opportunities, helping them succeed in the Major Leagues, or sharing expertise in analytics, arm care, and player development trends. It speaks volumes that many of his former players, from MLB to amateur levels, continue to rely on him for guidance and support.
I rely on Seth for complex pitching evaluations, mechanical analysis, projection work, and mental skills training. His impact is invaluable. I have no doubt that Seth will be a Major League Manager, and we are fortunate to have him mentoring local youth baseball players. With Seth, you are truly in great hands."
