Sol Kumin was a late bloomer in a few senses.

Kumin started playing lacrosse as a 10th-grader in Massachusetts and eventually was recruited by Dave Pietramala to play attack at Johns Hopkins.

After graduating and finding success on Wall Street — including starting his own hedge fund — Kumin found another passion in horseracing. A little over four years ago, he purchased his first horses. Now, he’s fresh off celebrating the 13th-ever Triple Crown with Justify, the horse of which he held a stake.

Kumin, vice chair of the US Lacrosse Foundation Board and an investor in the Premier Lacrosse League, shared with us his lacrosse journey.

How did you get into lacrosse?

I was a soccer goalie, and my school had a pretty good lacrosse team and no goalie. I was a decent athlete, so they threw me in the goal. I played goalie in 10th grade and didn’t love it. The next year, I ended up playing midfield. I picked it up quickly and I was a lefty. I had an unbelievable experience.

What’s your favorite memory from Johns Hopkins?

For the final four banquets, each coach picks one player to speak, and I was selected to speak on behalf of the Hopkins team. I remember looking at the four teams there, and we had beaten two of them earlier that season, and the other was in its first final four, Georgetown, so we were sitting in that room thinking we might actually win a national championship. Unfortunately, we lost to Virginia the next day, but it was a great experience, looking at your teammates and being selected to speak in front of everybody.

How did lacrosse help you on Wall Street?

I wasn’t an All-American in college, so you have to learn to work hard and be patient and push. There are a lot of lessons that helped me in life — learning how to be a good teammate, how to fight, how to compete.

How did you get into horseracing?

I had a buddy who is a builder out in Nantucket, Mass. He had grown up close to Saratoga Springs, and he had one horse at the time. He approached me and said, ‘Listen, I really think that you’ll like this sport. There’s a deal element to it. There’s spending time with your family.’ We put a small group of guys together; there were four of us. We bought [a few] horses and one of them turned out to be Lady Eli, who was our first tremendous horse. We named the horse after my wife, Elizabeth. It started off 6-0 and won the Breeder’s Cup.

What were you thinking as Justify crossed the finish line at the Belmont?

It was the most emotional of all the races. We had 130 friends and family there. You’re watching a horse cross the finish line and realizing that’s only happened 13 times in history, and you’re a part of that.
