He went on to pitch for the Los Angeles Angels. But just hours after pitching in his first starting game back in 2009, the 22-year-old was killed by a drunk driver.
This Saturday, his home town community remembered the local star with a 5K run at Williamsport High School in his memory, which is now in its fifth year.
"It really says a lot about our community here at Williamsport and in Washington County," said Williamsport head baseball coach, David Warrenfeltz, who was also Adenhart's former high school teammate.
"His ten year reunion is today so, a tough day to be honest," said Adenhart's mother, Janet Gigeous. "All his friends came out and some of them are in town for the class reunion tonight so, a special day."
A 1K was held for those ages three to eleven before the 5K began. Followed by a prayer and the national anthem, the runners took their place at the start line.
"What I like is we have kids and people who haven't done 3 miles maybe ever," Gigeous said. "Then we have elite runners who come out and really drop some amazing times. It's a very nice event."
The trail for the run was set around places where Adenhart left his legacy."We try to make it so it's all around where there's really strong memories of Nick," Gigeous added.
Proceeds go towards the Nick Adenhart foundation, which has had a big affect on the local baseball community."His foundation's been so good to baseball in our area, to our baseball program here at Williamsport and to baseball programs all across the country," Warrenfeltz said.
"We've raised a lot of money," Gigeous said. "We've been able to give all that money, a lot of it locally, to many of the little leagues and high schools in this area, and some of the areas in the minor leagues where Nick played."
At the end of the race, a raffle was held where participants and top runners received prizes such as hats, baseball tickets, and even a Nick Adenhart jersey."I just think it's great that even after his passing that Nick's legacy lives on," Warrenfeltz said. "He continues to leave a positive mark on so many people across our community."
