Self-Managed
Zack Hample is a recognizable baseball creator whose content blends MLB fandom, stadium travel, and highly shareable ball-catching moments. With an established audience on Instagram and YouTube, plus authentic ties to the game and a long track record of engaging baseball storytelling, he’s a strong partner for sponsors looking to reach passionate sports fans in a natural, credible way.
I'm one of the most recognizable sports fans in the world, known mainly as the guy who's caught more than 10,000 baseballs at major league games (including Mike Trout's 1st career home run and Alex Rodriguez's 3,000th hit). I have a big YouTube presence with a VERY engaged/obsessed fan base. I've written three baseball books, been on TV a ton, made appearances, given speeches, and been sponsored by numerous brands over the years, including SeatGeek, DraftKings, Gatorade, FujiFilm, and BIGS Sunflower Seeds. When I'm at a Major League stadium, a minimum of 100 people will recognize and approach me over the course of the day. It seems that everyone in the baseball world knows me at the point -- and it feels like I'm just getting started.

How do you measure influencer marketing ROI when half the numbers social media gives you are vanity metrics? It is the question brands ask us most, and it came up again when I joined Massimo Marinelli on the Berkida Ventures Podcast. After more than ten years and thousands of brand deals with athletes and creators at OpenSponsorship, here is how we think about it, and the framework we use with our clients.
