Marshall’s Tarr Hired as Assistant at Georgetown

August 20 - Aaron Tarr, who led Marshall to six straight league championships and to the VHSL Class 5 state final in 2015, has stepped down to take a position as an assistant coach at Georgetown University. 

The hire was made official on Friday, though Georgetown has not made a formal announcement. 

Tarr, 39, has overseen one of the area’s most-consistent programs this decade. Since he took the reigns prior to the 2013 season, the Statesmen have gone 116-49, winning 70 percent of their games and averaging 16.6 wins per season. They have won the past six National District championships, and have lost just two games against league foes over that stretch. 

“I loved the Marshall community and [director of student activities] Joe Swarm, but the opportunity to continue to learn and grow as a coach under Pete Wilk at Georgetown was too great to pass up,” Tarr said this morning. “I loved my seniors - one of my favorite groups - but had to consider my future and family in making this career decision.”

His 2015 team, led by NOVA Nine Team selection Mitch Blackstone and featuring four future Division I pitchers, advanced to the North Region and Class 5 state championship games before falling on both occasions to Stone Bridge.

Tarr played collegiately at Division III Hamilton College in New York and has spent 13 seasons as a high school coach, previously serving for three years as the junior varsity coach at his alma mater, Yorktown, and then a varsity assistant at Marshall. He has also coached with the FCA Braves in the Cal Ripken Collegiate Baseball League, with the Marucci Stars travel program and currently oversees the Cadets travel program.

At Georgetown, he will work with the team’s hitters and outfielders at a program that went 22-34 overall and 7-11 in the Big East Conference this past spring under longtime coach Pete Wilk. A number of area players will return to the Hoyas in 2020, including three juniors: infielder Yareb Martinez (Champe), catcher Ryan Davis (Oakton) and right-hander Owen Lamon (Oakton); and two sophomores: left-hander Jack Weeks (Paul VI Catholic) and right-hander Carter Bosch (Potomac School). 

Marshall’s vacancy has not yet been posted on the Fairfax County Public Schools website.
