Griest helping the Reds perform at their best
By Bruce Morgan
For a long time, Tim Griest’s post-high school plans were unclear.
The 2016 Warwick grad knew he wanted to go to McDaniel College to continue his baseball career.
Beyond that, however, Griest’s course of study was a question mark.
“Throughout high school, I can’t say I was the most academically motivated person,” he said. “I didn’t really have any idea what I wanted to do for a career or anything.”
As part of his athletic career with the Warriors, Griest enjoyed lifting weights and working out. Already, he was thinking about ways to improve his ex*****on as a pitcher on the diamond, and in the freestyle in swimming.
So his mother, Terri, suggested an avenue for him to explore.
“As I was getting close to college,” Griest recalled, “my mom said, ‘You like working out. Why don’t you try exercise science?’ And I was like, ‘Yeah, it sounds good to me.’”
Well, as things unfolded, that teenager who wasn’t academically motivated did a 180-degree turn. He found his calling.
Not only did Griest get his undergrad from the Green Terror, he pursued his passion for exercise physiology to earn a master’s degree at James Madison and his PhD at Florida State University.
Today, the 28-year-old is reaping the rewards of all his hard work. He was hired last summer by Major League Baseball’s Cincinnati Reds as an applied sports science coordinator.
“In addition to playing sports,” Griest remarked, “I’ve always been a huge fan of just watching sports. Growing up watching the Phillies, Sixers, and Eagles and now being within one of those leagues, especially early on, it was kind of surreal.”
His welcome to the Reds’ moment actually happened during his first day on the job. At the organization’s spring training complex in Arizona, where big leaguers on the long-term injured list work out with rehab staff, Griest reported for duty at the same time that Cincinnati pitcher Hunter Greene — a 2024 National League All-Star — was fine tuning his triple-digit four-seam fastball.
“I was walking in on day one and seeing one of the best pitchers in baseball there throwing a live BP,” he recalled, “so that was kind of cool.”
Thankfully, Griest had given his mother’s idea a shot. It was the beginning of what has indeed been a fulfilling journey.
The idea of a career in exercise science really started to take hold a couple of years into his education at McDaniel College when he got into the curriculum’s core classes.
“That was one of the first times I remember where I really dove into school and really started to enjoy going to class,” Griest said.
He continued to evolve, and it wasn’t until Griest got to FSU that he realized teams were hiring employees whose job title was sports science.
During his time in Tallahassee, he worked with the Seminoles’ football team, did his dissertation project with FSU’s softball squad, learned from mentors and made himself marketable.
Eventually, as fate would have it, Griest saw the Reds’ position become available, and he got a helping hand from one of his connections in the business.
“At the time, (my contact) was the director of sports science for the Houston Texans,” Griest said, “but he knew the director of sports science here with the Reds and helped facilitate at least the beginning stage of the interview process.”
The rest, as they say, is history.
Griest now resides in Goodyear, Ariz., which is located about half an hour from Phoenix, but he spends roughly half of his time on the road.
Since the Reds having sports science personnel assigned to each affiliate, Griest travels to the different outposts to collaborate with those people.
That could take him anywhere from Cincinnati to the Dominican Republic to Triple-A Louisville, Ky. to Single-A Daytona, Fla. and elsewhere.
“I like pretty much all aspects (of the job),” Griest said. “Honestly, the people here have been great. I really enjoy not only the players, they’re great to interact with every day, but we have a really good staff that I enjoy working with.”
Sports science is considered to be part of the baseball operations department, and the goal is to help players enhance their health and performance.
By collecting data in the weight room, Griest and his colleagues can gain insight into fatigue management and load monitoring.
Position players are tested in various running exercises — distance, change of direction, acceleration, deceleration — while pitchers are examined through throwing volume, or how much they’re slinging and at what intensity.
Evaluations over time might indicate that players are showing progress, or they could signify that an athlete is suffering from some fatigue.
The strategies at that point which Griest and his colleagues might explore for the players could then potentially delve into nutrition or recovery suggestions, or sleep tactics.
“At the end of the day, our goal is to keep guys on the field and performing at their best,” Griest said. “For the minor league guys, they want to get to the show. For the guys in the show, they want to stay in the show and maximize everything they can out of it.”
Speaking of that, maximizing was just what Griest was trying to do at Warwick. He likely wasn’t thinking about the show, but his desire to improve athletically steered him toward working out.
Little did he know at the time what it would lead to when Griest and his father, Dan, trained at the Lititz Rec after swim practices. He worked out periodically and had conversations with former Warwick High School athlete Cody Kimmel, who wound up as a personal trainer and became an inspiration.
Other mentors — professors, FSU football staff and Olympians — also had an impact on Griest along the way.
“That’s really helped to shape who I am and really helped me get to where I am today,” he said.
To be sure, the Reds’ front office is a long way from ten years ago.
